[0101] In one or more examples, each one of the grippers 302 follows the orbital path 310 when rotated about the axis 306. In other words, each one of the grippers 302 orbits or revolves around the axis 306. In one or more examples, during rotation, each one of the grippers 302 has a plurality of different radial positions 312 along the orbital path 310. Generally, the radial position 312 of the gripper 302 refers to an orbital location of the gripper 302 along the orbital path 310, a radial location of the gripper 302 relative to the axis 306, and/or a radial distance of the gripper 302 (e.g., outwardly) from the axis 306 along the orbital path 310.
[0102] In one or more examples, during rotation, the radial position 312 of the gripper 302 varies along the orbital path 310. As an example, during rotation, the radial position 312 of gripper 302 progressively increases (e.g., relatively more radially outward) along one or more portions of the orbital path 310 and progressively decreases (e.g., relatively less radially outward) along one or more other portions of the orbital path 310. In one or more examples, the gripper 302 oscillates between relatively more radially outward positions and relatively less radially outward positions along the orbital path 310.
[0103] In one or more examples, the orbital path 310 is non-circular. In one or more examples, the orbital path 310 resembles or approximates a heart-shape, for example, having two curved lobes that intersect at each end at a point. In one or more examples, the orbital path 310 is approximately symmetric. In one or more examples, the orbital path 310 is asymmetric. In one or more examples, the orbital path 310 includes a first portion 318 (e.g., a first half) and a second portion 320 (e.g., a second half). In one or more examples, the first portion 318 and the second portion 320 of the orbital path 310 are approximately mirror images of one another. In one or more examples, each one of the first portion 318 and the second portion 320 of the orbital path 310 has a complex curvature.
[0104] In one or more examples, the first portion 318 of the orbital path 310 moves the gripper 302 toward the first radial position 314 and away from a second radial position 316. In one or more examples, the second portion 320 of the orbital path 310 moves the gripper away from the first radial position 314 and toward the second radial position 316. In one or more examples, the first radial position 314 and the second radial position 316 are diametrically opposed to each other.
[0105] In one or more examples, the first portion 318 of the orbital path 310 ends and the second portion 320 of the orbital path 310 begins at the first radial position 314. In one or more examples, the second portion 320 of the orbital path 310 ends and the first portion 318 of the orbital path 310 begins at the second radial position 316.
[0106] In one or more examples, the first radial position 314 is at a first intersection or transition between the first portion 318 and the second portion 320 of the orbital path 310 in which the gripper 302 changes direction from a radially outward direction (e.g., radially outward motion) to a radially inward direction (e.g., radially inward motion). It is this change in direction along the orbital path 310 between the first portion 318 and the second portion 320 that causes or results in a (e.g., first) momentary pause in orbital motion of the gripper 302 at the first radial position 314.
[0107] In one or more examples, the second radial position 316 is at a second intersection or transition between the first portion 318 and the second portion 320 of the orbital path 310 in which the gripper 302 changes direction from a radially inward direction (e.g., radially inward motion) to a radially outward direction (e.g., radially outward motion). It is this change in direction along the orbital path 310 between the second portion 320 and the first portion 318 that causes or results in a (e.g., second) momentary pause in the orbital motion of the gripper 302 at the second radial position 316.
[0108] In one or more examples, the orbital path 310 includes a first loop 322 at the first intersection or transition between the first portion 318 and the second portion 320 of the orbital path 310. The first loop 322 of the orbital path 310 is configured to smoothly redirect the gripper 302 from radially outward motion to radially inward motion. The orbital path 310 includes a second loop 324 at the second intersection or transition between the first portion 318 and the second portion 320 of the orbital path 310. The second loop 324 of the orbital path 310 is configured to smoothly redirect the gripper 302 from radially inward motion to radially outward motion.
[0109] In one or more examples, at the beginning of the first portion 318 of the orbital path 310, the gripper 302 is at the second radial position 316 (e.g., a radially inward position, such as a most radially inward position). As the gripper 302 moves along the first portion 318, such as a second portion of the second loop 324, the gripper 302 moves radially outward along a first section of the first portion 318. As the gripper 302 moves further along the first portion 318, the gripper 302 moves radially inward along a second section of the first portion 318. As the gripper 302 moves further along the first portion 318, such as along a first portion of the first loop 322, the gripper 302 again moves radially outward to the first radial position 314 (e.g., a radially outward position, such as a most radially outward position).
[0110] In one or more examples, at the beginning of the second portion 320 of the orbital path 310, the gripper 302 is at the first radial position 314 (e.g., a radially outward position, such as a most radially outward position). As the gripper 302 moves along the second portion 320, such as along a second portion of the first loop 322, the gripper 302 moves radially inward along a first section of the second portion 320. As the gripper 302 moves further along the second portion 320, the gripper 302 moves radially outward along a second section of the second portion 320. As the gripper 302 moves further along the second portion 318, such as along a first portion of the second loop 324, the gripper 302 again moves radially inward to the second radial position 316 (e.g., a radially inward position, such as a most radially inward position).
[0111] In one or more examples, during rotation of the grippers 302, each one of the grippers 302 is configured to disengage and release the blank 100 at a third radial position 326 along the orbital path 310 to deposit the blank 100 on the group 106 of the articles 104. Accordingly, the third radial position 326 may also be referred to as a release or deposition position of the gripper 302. In one or more examples, the third radial position 326 is a radially outward position along the second portion 320 of the orbital path 310 in which the gripper 302 and, thus, the blank 100 are positioned over the group 106 of the articles 104.
[0112] As such, in one or more examples, the gripper 302 follows the first portion 318 of the orbital path 310 for proper positioning to engage and retrieve the blank 100 at the first radial position 314. The gripper 302 follows the second portion 320 of the orbital path 310 for proper positioning to transfer the blank 100 and deposit the blank 100 onto the group 106 of the articles 104 at the third radial position 326.
[0113] Accordingly, the shape of the orbital path 310 and/or the curvatures of the different portions of the orbital path 310 are configured to selectively control the radial position 312 of the gripper 302 while the gripper 302 is continuously rotated about the axis 306. More particularly, the shape of the orbital path 310 and/or the curvatures of the different portions of the orbital path 310 are configured selectively move the gripper 302 between radially inward positions (e.g., in a radially inward direction) and radially outward positions (e.g., in a radially outward direction) while the gripper 302 is continuously rotated about the axis 306. Even more particularly, the shape of the orbital path 310 and/or the curvatures of the different portions of the orbital path 310 are configured to momentarily pause orbital motion of the gripper 302 at one or more positions along the orbital path 310 while the gripper 302 is continuously rotated about the axis 306.
[0114] While a particular configuration and/or example of curvature of the orbital path 310 and, more particularly, examples of the first portion 318 and the second portion 320 of the orbital path 310, have been described above and illustrated in
[0115] In various examples, the feeder apparatus 300 and, more particularly, the guide 308 includes any suitable mechanism configured to controllably move the grippers 302 along the orbital path 310 while continuously rotating the grippers 302 about the axis 306.
[0116] In one or more examples, the grippers 302 pick the blank 100, for example, from the supply 204 of the blanks 100 in the hopper 232 (
[0117] In one or more examples, each one of the grippers 302 includes or takes the form of any suitable mechanism configured to selectively grip, hold, and release the blank 100. In one or more examples, the gripper 302 includes or takes the form of a vacuum gripper. As an example, the gripper 302 includes a vacuum cup or a suction cup that is coupled to and that is in fluid communication with a vacuum source, such as a vacuum pump. In other examples, one or more of the grippers 302 includes or takes the form of another type of gripping mechanism, such as a mechanical grasper or manipulator, an adhesive gripper, an electrostatic gripper, and the like.
[0118] In one or more examples, the grippers 302 are equally angularly spaced away from each other. As an example, the feeder apparatus 300 includes six grippers 302 and each one of the grippers 302 is equally angularly displaced from a directly adjacent one of the grippers 302 by approximately 60 degrees. In other examples, the feeder apparatus 300 includes any suitable number of grippers 302, which are equally angularly displaced from one another.

[0120] In one or more examples, the feeder drive 304 is configured to rotate the gripper arms 328 about the axis 306. In one or more examples, the guide 308 is configured to position each one of the gripper arms 328 along the orbital path 310 during rotation about the axis 306. During rotation, each one of the gripper arms 328 has at least two radial positions 312 along the orbital path 310. Orbital motion of each one of the gripper arms 328 along the orbital path 310 is momentary paused at the first radial position 314. When the gripper arm 328 is at the first radial position 314 along the orbital path 310 and orbital motion is momentarily paused, the grippers 302 engages and retrieves the blank 100.
[0121] In one or more examples, each one of the gripper arms 328 follows the orbital path 310 when rotated about the axis 306. In other words, each one of the gripper arms 328 orbits or revolves around the axis 306. In one or more examples, during rotation, each one of the gripper arms 328 has a plurality of different radial positions 312 along the orbital path 310. Generally, the radial position 312 of the gripper arms 328 refers to an orbital location of the gripper arm 328 along the orbital path 310, a radial location of the gripper arm 328 relative to the axis 306, and/or a radial distance of the gripper arm 328 (e.g., outwardly) from the axis 306 along the orbital path 310.
[0122] In one or more examples, the gripper arms 328 are equally angularly spaced away from each other. As an example, the feeder apparatus 300 includes six gripper arms 328 and each one of the gripper arms 328 is equally angularly displaced from a directly adjacent one of the gripper arms 328 by approximately 60 degrees.

[0126] In one or more examples, the feeder drive 304 includes a drive shaft 334. The drive shaft 334 is coupled to the rotary drive 330. The rotary drive 330 rotates the drive shaft 334 about the axis 306. The gripper hub 332 is coupled to the drive shaft 334. The gripper hub 332 is rotationally fixed relative to the drive shaft 334 such that the gripper hub 332 rotates with the drive shaft 334 and is, thereby, rotationally driven by the rotary drive 330.
[0127] In one or more examples, the feeder drive 304 includes a second gripper hub 336. The second gripper hub 336 is spaced away from the gripper hub 332 and is coupled to the drive shaft 334. The second gripper hub 336 is rotationally fixed relative to the drive shaft 334 such that the second gripper hub 336 rotates with the drive shaft 334 and the gripper hub 332 and is, thereby, rotationally driven by the rotary drive 330.

Each one of the support rods 358 is coupled to the drive shaft 334 at a second end, opposite the first end. In one or more examples, the support rod 358 is coupled to a coupling 360. The coupling 360 is coupled to the drive shaft 334. The coupling 360 is rotational fixed relative to the drive shaft 334 such that the coupling 360 and, thus, the support rod 358 rotate about the axis 306 with the drive shaft 334. The support rod 358 is linearly movable relative to the coupling 360. As an example, the support rod 358 is linearly movable relative to the coupling 360 to accommodate changes in the radial position 312 of the gripper arm 328 along the orbital path 310 as the gripper arm 328 rotates about the axis 306.

[0138] In one or more examples, in order to control the rotational or pivotable motion of the output lever 352 about the axis 356 and, thus, the radial position 312 of the gripper 302 or the gripper arm 328 along the orbital path 310, the cam follower 346, the first end of the input lever 348, and/or the axis 354 are configured to be located behind, stay located behind, and/or to trail behind the second end of the input lever 348, the gear box 350, and/or the axis 356 in the direction of rotation (e.g., indicated by directional arrow 362).
[0139] In one or more examples, the gear box 350 includes an overdrive gear ratio such that the output angular motion of the output lever 352 is greater than the input angular motion of the input lever 348. As an example, the angular range of motion 364 of the input lever 348 is 90 degrees and the corresponding angular range of motion 366 of the output lever 352 is 360 degrees. As such, as the input lever 348 rotates or pivots about the axis 356 within its angular range of motion 364, the output lever 352 rotates or pivots about the axis 356 within its angular range of motion 366, which is some multiple (e.g., 4 times) higher than the angular range of motion 364 of the input lever 348. In other examples, other overdrive gear ratios may be used.
[0140] In one or more examples, the gear box 350 includes or takes the form of a planetary gearbox. In one or more examples, the gear box 350 includes or takes the form of a spur gear.
[0141] In one or more examples, the disclosed feeder apparatus 300 provides various benefits over traditional rotary vacuum feeders. The present disclosure recognizes that traditional rotary vacuum feeders suffer from guiding loss and non-optimal motion law due to utilization of a double cam follower. These two factors, among others, can prevent traditional feeders from being able to move fast enough to enable a high throughput. Examples of the disclosed feeder apparatus 300 utilizes a single cam follower, which overcomes both of the above-identified disadvantages by eliminating guiding loss and optimizing motion such that the blank-feeding operation and motion is smoother and faster to enable high throughput.

The first tool hub 414 and the second tool hub 416 are coupled to the rotary drive 418. The rotary drive 418 rotates the first tool hub 414 about the first axis 408 and rotates the second tool hub 416 about the second axis 410. In one or more examples, the first tool hub 414 and the second tool hub 416 share and are rotated by the same rotary drive 418. In one or more examples, each one of the first tool hub 414 and the second tool hub 416 has and is rotated by a dedicated rotary drive 418.

The drive shaft or other power transmission component is coupled to the rotary drive 418. The first tool hub 414 and the second tool hub 416 are coupled to the drive shaft or other power transmission component such that the first tool hub 414 and the second tool hub 416 rotate with drive shaft or are rotated by the power transmission component and, thereby, rotationally driven by the rotary drive 418.

[0157] Similarly, in one or more examples, the second applicator tools 404 are equally angularly spaced away from each other. As an example, the applicator apparatus 400 includes three second applicator tools 404 (e.g., as shown in
[0158] In one or more examples, the first applicator tools 402 and the second applicator tools 404 are equally angularly displaced from and/or equally angularly oriented relative to each other such that each one of the first applicator tools 402 and the second applicator tools 404 sequentially and alternatingly move through a blank application motion, referred to herein as a stroke 412, as the alternating first ones and second ones of the groups 106 and the corresponding blanks 100 move along the travel path 202 and through the applicator apparatus 400.
[0159] Referring still to
[0160] In one or more examples, the first applicator tools 402 and the second applicator tools 404 are appropriately angularly oriented relative to each other such that each one of the first applicator tools 402 and the second applicator tools 404 alternatingly moves through its respective stroke 412. In one or more examples, the first applicator tool 402 reaches a downward most position of the stroke 412 before the second applicator tool begins the stroke 412. In one or more examples, the second applicator tool 404 reaches a downward most position of the stroke 412 before the first applicator tool begins the stroke 412.
[0161] Generally, the rotational speed of the first applicator tools 402 about the first axis 408 and the rotational speed of the second applicator tools 404 about the second axis 410 are suitably synchronized such that the first applicator tools 402 and the second applicator tools 404 performing alternating strokes 412.
[0162] In one or more examples, the stroke 412 is sufficient to press the blank 100 downward a distance sufficient to ensure that the upper ends of the articles 104 are received through the retention apertures 128 of the blank 100 (
[0163] Accordingly, use of the angularly displaced first applicator tools 402, rotated about the first axis 408 by the first tool hub 414, and use of the angularly displaced second applicator tools 404, with synchronized rotation about the second axis 410 by the second tool hub 416, enables a deeper stroke as compared to traditional blank application machines and enables suitably high processing speeds or throughput. The deeper stroke produced by the disclosed applicator apparatus 400 is particularly beneficial during packaging of plastic bottles.

[0189] In one or more examples, the blank 100 is formed from a sheet of suitable substrate. As used herein, the term suitable substrate includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognized that any number of (e.g., one or more) blanks 100 may be employed where suitable, for example, to provide and/or form one or other numbers of cartons 102 (e.g., carrier structures) described in more detail below.
[0190] In one or more examples, the blank 100 and, thus, the carton 102 are formed from a sheet material, such as a paperboard substrate. The paperboard substrate may be, for example, a solid bleached sulfate (SBS) substrate, an uncoated natural kraft (UNC) substrate, or a coated natural kraft (CNK) substrate. The paperboard substrate may be formed from virgin fibers, recycled fibers, or combinations thereof.
[0191] In one or more examples, the blank 100 and, thus, the carton 102 are formed from a sheet material such as paperboard, which may be made of materials or coated with materials to increase its strength. An example of such a sheet material is tear resistant NATRALOCK paperboard made by WestRock Company. In one or more examples, the tear resistant materials are provided by more than one layer to help improve the tear-resistance of the carton 102.
[0192] In one or more examples, the blank 100 includes at least a paperboard substrate. The material of the paperboard substrate may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10 pt., preferably from about 16 pt. to about 28 pt. (0.028/0.7mm). An example of such a substrate is a 27-point (pt.) SBS board (solid bleached sulfate paperboard coated on one side, trade name PrintKote) or CNK board (Coated Natural Kraftan unbleached kraft paperboard having a clay coating on one side, trade name CarrierKote) manufactured by WestRock Company. The paperboard substrate may be a bleached or unbleached board. The board may be coated on at least one side, optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and board composition.
[0193] In one or more examples, one surface of the sheet material has different characteristics to the other surface. For example, the surface of the sheet material that faces outwardly from a finished carton 102 may be particularly smooth and may have a coating, such as a clay coating or other surface treatment, to provide good printability. The surface of the sheet material that faces inwardly may, on the other hand, be provided with a coating, a layer, and/or a treatment or be otherwise prepared to provide properties such as one or more of tear-resistance, good glue-ability, heat sealability, or other desired functional properties.
[0194] In one or more examples, the blank 100 may include a tear resistant layer laminated to the paperboard layer. It optionally includes an adhesive layer between the paperboard substrate and the tear resistant layer. The tear resistant layer may be disposed over the uncoated side of the paperboard substrate and may be formed of polymeric material and secured to the substrate. The tear resistant layer imparts toughness to the laminate structure. Suitable tear resistant materials may include, but not be limited to, tear resistant laminated sheet material, e.g., NATRALOCK, which may include a layer of an n-axially oriented film, e.g., MYLAR, which is a bi-axially oriented polyester, oriented nylon, cross-laminated polyolefin, or high-density polyolefin. The orientation and cross-laminated structure of these materials contribute to the tear resistant characteristic. Also, tear resistance may be attributed to the chemical nature of the tear resistant material such as extruded metallocene-catalyzed polyethylene (mPE).
[0195] Alternatively, in one or more examples, the tear resistant layer may be a layer of linear low-density polyethylene (LLDPE). In examples where linear low-density polyethylene (LLDPE) or mPE is used, it is not necessary to incorporate an adhesive layer. Other suitable materials having a high level of tear resistance may also be used. The adhesive layer may be formed of polyolefin material such as a low-density polyethylene (LDPE). The adhesive layer may be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.
[0196] The preceding detailed description refers to the accompanying drawings, which illustrate specific examples of the disclosed system, feeder apparatus, applicator apparatus, method for packaging, method for transferring, and method for applying as described by the present disclosure. It will be understood that the disclosed examples are merely exemplary embodiments of the way in which certain aspects of the of the disclosed system, feeder apparatus, applicator apparatus, and methods can be implemented and do not represent an exhaustive list of all of the ways the of the disclosed system, feeder apparatus, applicator apparatus, and methods may be embodied. Other examples having different structures and operations do not depart from the scope of the present disclosure. Like reference numerals may refer to the same feature, element, or component in the different drawings. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. Throughout the present disclosure, any one of a plurality of items may be referred to individually as the item and a plurality of items may be referred to collectively as the items. Moreover, as used herein, a feature, element, component, or step preceded with the word a or an should be understood as not excluding a plurality of features, elements, components, or steps, unless such exclusion is explicitly recited.
[0197] Illustrative, non-exhaustive examples, which may be, but are not necessarily, claimed, of the subject matter according to the present disclosure are provided above. Reference herein to example means that one or more feature, structure, element, component, characteristic, and/or operational step described in connection with the example is included in at least one aspect, embodiment, and/or implementation of the subject matter according to the present disclosure. Thus, the phrases an example, another example, one or more examples, and similar language throughout the present disclosure may, but do not necessarily, refer to the same example. Further, the subject matter characterizing any one example may, but does not necessarily, include the subject matter characterizing any other example. Moreover, the subject matter characterizing any one example may be, but is not necessarily, combined with the subject matter characterizing any other example.
[0198] It is to be understood that not necessarily all objects or advantages may be achieved in accordance with any particular example described herein. Thus, for example, those skilled in the art will recognize that certain examples may be configured to operate in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein.
[0199] It should be appreciated that, when used to modify a structure, an element, an item, a component or a feature described herein, the terms front, back, rear, bottom, top, left, right, side, end, upper, lower, inner, outer, as well as similar terms or other forms of such terms, are relative and refer to an example of a spatial relationship between structures, elements, items, components or features. As such, examples of the blank 100 and the carton 102, described herein and illustrated in the figures, are not intended to be limited by the specific relative terms used to describe any structure, element, item, component or feature thereof.
[0200] As used herein, the terms hinged connection and fold line refer to all manner of lines that define hinge features of the blank, facilitate folding portions of the blank with respect to one another, or otherwise indicate optimal panel folding locations for the blank. Any reference to hinged connection should not be construed as necessarily referring to a single fold line only; indeed, a hinged connection can be formed from two or more fold lines wherein each of the two or more fold lines may be either straight/linear or curved/curvilinear in shape. When linear fold lines form a hinged connection, they may be disposed parallel with each other or be slightly angled with respect to each other. When curvilinear fold lines form a hinged connection, they may intersect each other to define a shaped panel within the area surrounded by the curvilinear fold lines. A typical example of such a hinged connection may include a pair of arched or arcuate fold lines intersecting at two points such that they define an elliptical panel therebetween. A hinged connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinged connection may comprise a combination of a linear fold line and an arched or arcuate fold line which intersect at two points such that they define a half moon-shaped panel therebetween.
[0201] As used herein, the term fold line may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cutline, a line of aligned slits, a line of scores and any combination of the aforesaid options.
[0202] It should be understood that hinged connections and fold lines can each include elements that are formed in the substrate of the blank including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cutline, an interrupted cutline, slits, scores, embossed lines, debossed lines, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking, to facilitate folding and facilitate breaking with more effort, or to facilitate breaking with little effort.
[0203] As used herein, the terms rotate, rotating, rotation, and similar terms refer to movement of a body around an axis and includes a condition in which the axis extends through a center of mass of the body (e.g., rotate), a condition in which the axis extends through the body, but not through the center of mass of the body (e.g., gyrate or pivot), and a condition in which the axis does not extend through the body (e.g., revolve).
[0204] Conditional language such as, among others, can or may, unless specifically stated otherwise, are otherwise understood within the context as used in general to convey that certain examples include, while other examples do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more examples or that one or more examples necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular example.
[0205] Unless otherwise indicated, the terms first, second, third, etc. are used herein merely as labels, and are not intended to impose ordinal, positional, or hierarchical requirements on the items to which these terms refer. Moreover, reference to, e.g., a second item does not require or preclude the existence of, e.g., a first or lower-numbered item, and/or, e.g., a third or higher-numbered item.
[0206] Those skilled in the art will appreciate that not all elements, features, components, and/or operational steps described and illustrated in
[0207] Further, references throughout the present specification to features, advantages, or similar language used herein do not imply that all of the features and advantages that may be realized with the examples disclosed herein should be, or are in, any single example. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an example is included in at least one example. Thus, discussion of features, advantages, and similar language used throughout the present disclosure may, but do not necessarily, refer to the same example.
[0208] The described features, advantages, and characteristics of one example may be combined in any suitable manner in one or more other examples. One skilled in the relevant art will recognize that the examples described herein may be practiced without one or more of the specific features or advantages of a particular example. In other instances, additional features and advantages may be recognized in certain examples that may not be present in all examples. Furthermore, although various examples of the blank 100, the system 200, the feeder apparatus 300, the applicator apparatus 400, the method 1000 for packaging, the method 2000 for transforming, and the method 3000 for applying have been shown and described, modifications may occur to those skilled in the art upon reading the specification. The present application includes such modifications and is limited only by the scope of the claims.
