Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.

A method and a machine for forming a box from a blank, in which the blank is removed from a storage magazine by suction, the blank is fed horizontally above a support having an upper edge with a V-shaped cross section and faces that correspond to the main walls and are inclined with respect to the horizontal by a given angle a, such that the central folding line, known as the reference folding line, is next to the edge, the blank is placed on the support, the blank is then pressed against a polygonal mandrel, the upper edge of which coincides with and/or is in line with the upper edge of the support, said mandrel having a shape complementary to that of the box, so as to form a tubular box body at an angle to the horizontal, the bottom of the box is formed by folding and pressing together flaps after application of glue, and the inclined box thus formed is ejected, is positioned upright and then is transferred to a filling station.

A machine for forming packing templates includes a infeed system that can feed multiple feeds of sheet material into the machine without repositioning the infeed system or forming creases or bends in the sheet material. The machine also includes a separation and cutting systems with one or more cutting tables and biased knives that cut the sheet material packaging templates. The machine also includes creasing roller(s) that forms creases in the sheet material. The machine also includes a system for reducing or eliminating the impact of irregularities in the sheet material.

A box gluing device for attaching a glue tab of a box blank to an opposing panel when the box blank is folded so the glue tab is position at an edge of the box blank. The gluing device includes a support structure upon which a gluing apparatus and a support plate are mounted. The gluing apparatus a glue dispensing nozzle for applying glue on one or more surfaces of the box blank. The box blank can be moved through the gluing device to attach the glue tab to the opposing panel. As the box blank moves through the gluing device, a guide rail orients the glue tab in a desired manner while glue is applied to the box blank, and a roller assembly presses the glue tab and the opposing panel together with the glue therebetween. Alternatively, the gluing device can include a clamp arm that holds the box blank in place while glue is applied, and a folding bar that folds the glue tab onto the opposing panel after glue is applied.

A machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.

A cardboard casket includes a top piece and a bottom piece. The top piece is formed by making a single press die cut in a reinforced core cardboard panel, including cutting the reinforced core cardboard panel to form the top piece and forming seams in the top piece. The bottom piece is formed by making another single press die cut in another reinforced core cardboard panel, including cutting the other reinforced core cardboard panel to form the bottom piece and forming seams in the bottom piece. Cutting the top and bottom pieces includes cutting through a first layer, a reinforced core, and a second layer of the reinforced core cardboard panels. Forming seams in the top and bottom pieces includes deforming the first layer in the seams, deforming a majority of the reinforced core in the seams, and leaving the second layer in the seam uncut.

A package generation system creates a package definition file for creation of a package flat. The file includes dimensions for cut lines along which the package will be separated from a two dimensional substrate. The flat includes facets and functional elements that connect the facets. The system will identify a pair of the functional elements that have a connecting relationship. The first facet of the pair is a tab structure having a symmetric design, and the second facet of the pair is a receiving structure. If the tab structure and receiving structure are connected to cut lines that intersect at a pivot point, the system will convert the definition of the tab structure from the symmetric design to a non-symmetric design. It will save dimensions for the edges and functional elements in the package design file with the non-symmetric design.

In a folder-gluer, push-out forces by an air cylinder and a push-out spring mechanism are set such that: (1) when downstream portions of first and fourth panels are passing through a second bending plate, the second bending plate is pushed outwardly in a width direction by the push-out forces to extend the downstream portions of the first and fourth panels in the width direction; and (2) when upstream portions of the first and fourth panels are passing through the second bending plate, the second bending plate is pushed back inwardly in the width direction by the resistance force applied to the second bending plate by the first and fourth panels so as not to extend the upstream portions in the width direction, and wherein the push-out forces are not varied by a control while the first and fourth panels are passing through the second bending plate.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A multivariable perforated adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.
