Abstract: Methods and apparatuses for manufacturing portions of absorbent articles may include or facilitate conveying a substrate through a nip formed between a first device and a second device, transmitting vibrational energy from the second device toward the first device via the nip to alter the substrate, and cooling the second device by transferring thermal energy from the second device.

Abstract: Apparatus and process are described for forming projections on a substrate for use as hook-type fasteners in touch fastening systems, wherein vibration energy may be used to soften a substrate which may be positioned between a mold and a source of vibration. The mold may include a plurality of cavities into which the softened substrate may be forced to form the projections. The substrate may comprise a film, sheet, web, composite, laminate, etc. and be useful as an attachment strip for temporary or permanent fastening. The source of vibration may be an ultrasonic horn. The process to form such projections may be operated in a continuous, semi-continuous or intermittent manner.

Abstract: Embodiments related to a touch fastener and its methods of manufacture and use are disclosed. In one embodiment, the touch fastener may include a substrate with a first portion and a second portion displaceable relative to the first portion. A first fastening element may be formed in the first portion. When the first portion is displaced relative to the second portion, a force and/or moment generated by the displacement may cause the first fastening element to be deployed.

Abstract: An extruded hook fastener strip is created on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll. The second strip is firmly bonded to the fastener strip on that side opposite the formed hooks.

Abstract: A fastener of the hook and loop type intended to be incorporated into plastic articles by plastic molding processes is formed of a known separable fastener member having a base member and a plurality of engaging elements upstanding from one surface thereof. A vinyl plastisol, thermoplastic, or rubber encasement which intimately surrounds the individual engaging elements protects the elements when they are exposed to the harsh environment of a molding process. The fastener is placed in a mold and molded into, as an integral part thereof, a plastic part. The encasement is removable from the engaging elements after the molding process, to expose the engaging elements, without permanently deforming or substantially destroying the fastening performance thereof.

Abstract: A fastener of the hook and loop type intended to incorporated into plastic articles by plastic molding processes is formed of a known separable fastener member having a base member and a plurality of engaging elements upstanding from one surface thereof. A vinyl plastisol, thermoplastic, or rubber encasement which intimately surrounds at least some of the individual engaging elements protects the elements when they are exposed to the harsh environment of a molding process. The fastener is placed in a mold and molded into, as an integral part thereof, a plastic part. The encasement is removable from the engaging elements after the molding process, to expose the engaging elements, without permanently deforming or substantially destroying the fastening performance thereof.

Abstract: A hook or loop component of a hook and loop fastener having a textile ground sheet and filamentary pile, the ground sheet penetrated by a resinous binder of improved properties. Hydrolytically stable cross-linked bonds are formed in a binder under ambient or laundering conditions. Bonds of urea-, ureido-, or urethane-type result from curing of the hook or loop ground-sheet by exposure to water molecules, polyfunctional amines, or polyfunctional alcohols. The resin is applied as a hot-melt, as a neat liquid, or as a solute in a solvent. In a method for applying the resin as a hot-melt, a continuous strip of hook or loop elements is heated to approximately the same temperature as the melted resin and the melted resin is applied, using a coating head and coating knife, to a section of tape suspended between two support points. Other cross-link systems and thermoplastic systems are disclosed.

Abstract: This invention describes a hook design for the hook portion of a hook and loop fastener system, and the hook strip made up of a multiplicity of such hooks projecting from a common base. The hook design encompasses a thickened stem portion projecting from the base and connecting to lobes of a crook portion at a neck. The stem portion is substantially thicker than the crook portion and terminates at the neck. The lobes and the stem are tapered whereby the hook can be easily withdrawn from its mold cavity during the molding operation. The hook is characterized by improved engageability and closure performance.

Abstract: A fastener of the hook and loop type intended to be incorporated into plastic articles by plastic molding processes is formed of a known separable fastener member having a base member and a plurality of engaging elements upstanding from one surface thereof. A covering which intimately surrounds the individual engaging elements protects the elements when exposed to the harsh environment of a molding process. This protecting covering is removable from the fastener after the molding process to expose the engaging elements without substantially destroying the performance thereof.

Abstract: A method for making an extruded hook fastener strip on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll is provided. The second strip is firmly bonded to the fastener strip on the side opposite the formed hooks.

Abstract: A strip of fastener material adapted for securing to the surface of a foam bun during molding, carries on a first surface an area of outwardly extending elements constituting one half of a touch fastening system. The first surface is arranged to be positioned so that it faces into a trough in a mold wall and this first surface is provided with a pair of elongated flexible sealing lips adjacent the edges of the area. Magnetizable means are also carried by the strip and the fastener strip has portions extending laterally beyond the sealing lips and beyond the edges of the trough in the mold wall.

Abstract: An improved hook for hook and loop fasteners having a profile defined by an inner smoothly contoured generally concave face and an outer generally convex face, said hook comprising a sturdy base intimately engaging a substantially planar base member and extending therefrom to join a resilient hook portion, able to engage a loop applying a force to the hook portion substantially normal to the base member, terminating in a free end, wherein the hook tapers smoothly and continuously downwardly in width from the sturdy base member to the free end such that a loop engaging the hook in tension, with the applied force being substantially normal to the base member, will deform the hook portion resiliently under the applied force to release the loop at a desired applied force and such that a loop engaging the hook in shear, with the applied force substantially parallel to the base member, will engage the sturdy base member, the sturdy base member being sufficiently sturdy that it will not deform to release a loop enga
