Method of laminating a performance-enhancing layer to a seamless three dimensional glove
11141966 · 2021-10-12 · ·

A method of manufacturing an enhanced, 3D, hand-shaped glove includes placing a seamless textile glove shell onto a laminating form, placing a solid laminate preform onto the glove shell, and applying pressure at an elevated temperature to laminate the preform to the glove shell. A platen or roller press can apply pressure to a glove shell on a flat surface of a laminating form, or a bladder or vacuum bag press can apply pressure to a glove shell on a curved surface of a laminating form. Edge peel resistance can be enhanced by extending the perimeter of a low modulus upper preform layer beyond underlying layers and bonding it directly to the glove shell. Fingers of the laminating form can be made wide and thin to cause warping of the preform about the glove fingers, or narrow and thick to minimize distortion of the finger shapes due to the preform.

METHOD AND APPARATUS FOR ASSEMBLING ABSORBENT ARTICLES
20210307970 · 2021-10-07 ·

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

Multi-stage debulk and compaction of thick composite repair laminates

A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.

Label stacking machine and method

A method of making a pad of labels comprises: printing display information on a top surface of a substrate; affixing a first layer of lamination material to a bottom surface of the substrate; affixing a second layer of lamination material to the top surface of the substrate, the second layer of lamination material having a release coating applied to a top surface thereof; applying an adhesive strip to a bottom surface of the first layer of lamination material, the adhesive strip being covered by a liner material; cutting the substrate having first and second layers of lamination material affixed into at least one label; removing the liner material to expose the adhesive strip after cutting the substrate into at least one label; and arranging the labels into a pad of labels.
