MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR LAMINATE
In a manufacturing method, resin in a molten state which becomes a film raw material is caused to hang down from a discharge port of a discharger and the film-like film raw material is continuously discharged, a sheet is conveyed along a sheet pass line, a tip part of the film raw material is formed by cutting and removing an initially formed part of the initially formed film raw material, the tip part is overlapped on the sheet on the sheet pass line, the sheet and the film raw material in a mutually overlapping state are conveyed along the sheet pass line, and the sheet and the film raw material are introduced to a joining part from the sheet pass line.
BEAMED ELASTOMERIC LAMINATE STRUCTURE, FIT, AND TEXTURE
The present disclosure relates to stranded elastomeric laminates (including bi-laminates and tri-laminates) comprising beamed elastics and may have inventive Dtex-to-Nonwoven-Basis-Weight-Ratios, Dtex-to-Spacing-Ratios, and/or Void-Area-to-Strand-Area-Ratios. The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.
Method and system for forming packages
A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.
Curved elastic with entrapment
An apparatus for manufacturing an elastic composite structure includes a first roller configured to transport a web layer in a machine direction and a laydown guide configured to guide a laydown pattern of a plurality of elastic threads. A rotary anvil comprises a first weld line having a first notch formed in a contact surface of the first weld line, the first notch having a first interior configured to receive a portion of a first elastic thread of the plurality of elastic threads and a portion of the web layer therein. The first notch comprises a facing surface defining at least a portion of the first interior. A smallest orientation angle of a first face axis normal to the facing surface with respect to a contact surface axis normal to the contact surface is a first angle that is less than 90 degrees.
Method and apparatus for assembling apertured elastic laminates
The present disclosure relates to methods for making apertured elastic laminates that may be used as components of absorbent articles. The methods and apparatuses may be close coupled such that materials may advance directly between aperturing and bonding operations. Such close coupling of devices may help to more precisely control the positions of the apertures in substrates relative to positions of apertures opposing substrates and/or bonds in the assembled laminate. The methods and apparatuses herein may also provide the ability to orient protrusions or protuberances in the substrates created by the aperturing process so as to extend inward and away from both outer surfaces of the assembled laminate. In turn, the assembly processes may be conducted so as to help mitigate reductions in softness that might otherwise result from the aperturing process in the assembled laminate.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.
Method and apparatus for manufacturing absorbent sanitary products and an absorbent sanitary product
A method for manufacturing absorbent sanitary products, comprising the steps of: forming a first and a second continuous elastic band, which are movable parallel to each other in a machine direction, fixing a plurality of absorbent panels between said first and second continuous elastic bands, arranged in a direction transverse to the machine direction, and spaced apart in said machine direction, wherein each of said elastic bands is formed by means of a method comprising the steps of: continuously feeding a plurality of tensioned elastic threads (30) in said machine direction, continuously feeding a pair of non-elastic webs arranged on opposite sides of said plurality of elastic threads, welding said pair of non-elastic webs to each other by means of a welding pattern comprising anchoring welds and/or containing and guiding welds.
Mesh fence material and method for making thereof
A method for producing a fencing material including the steps of: providing a border material having an interior surface; providing a mesh material having a front and a back; treating the interior surface of the border material to produce a tacky border material surface; placing a portion of the front and/or the back of the mesh material against the tacky border material surface; pressing the tacky border material surface and the mesh material together; and thermally bonding at least some portion of the front and the back of the mesh material with the interior surface of the border material. The border material being a polyvinyl chloride, the mesh being a polyvinyl chloride material and/or a vinyl coated material.
DEVICE AND METHOD FOR MANUFACTURING LAYERED SHEET
A layered body containing continuous sheets is thermally fused when passing through a space between an anvil roll and an energy applying device to form a layered sheet. A nip stage for sandwiching the layered body is provided upstream of the space between the anvil roll and the energy applying device. The nip stage includes at least one displacement member which is displaced in accordance with the thickness of the layered body sandwiched by the nip stage. Whether the thickness of the layered body sandwiched by the nip stage has deviated from a reference range is detected on the basis of the displacement of the displacement member, and when it is detected that the thickness has deviated from the reference range, the energy applying device is caused to retreat in a direction going away from the anvil roll.
Laminate(s) comprising beamed elastics and absorbent article(s) comprising said laminate(s)
The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
