METHOD OF MAKING A LAMINATE WITH A STRETCHED THERMOPLASTIC LAYER

The method of making a laminate (100) includes stretching a thermoplastic layer (102) so that it plastically deforms, relaxing the plastically deformed thermoplastic layer (102) to reduce its tensile strain, and subsequently laminating the thermoplastic layer (102) to a substrate (104) to make the laminate (100). The stretching, relaxing, and laminating are completed in-line. The thermoplastic layer has a first surface and a second surface opposite the first surface, with the first surface of the thermoplastic layer bearing a plurality of male fastening elements. The second surface of the thermoplastic layer (100) is laminated to the substrate (104).

The thermoplastic layer is plastically deformed and has a retardance profile having an average retardance along a line from the first edge to a location 500 micrometers from the first edge and a distance from the first edge where 75% of the average retardance is observed of at least 10 micrometers. In some cases, a distance between the first and second side edges is up to 50 millimeters. In some cases, the article is a fastening tab. The method includes providing a thermoplastic film having opposing first and second side edges, with a distance between the opposing side edges of up to 50 millimeters, and stretching the thermoplastic film to form the thermoplastic layer, which is plastically deformed. The first surface of the thermoplastic film bears male fastening elements.

A molding apparatus includes a movable molding surface with molding cavities, a pressure shoe with a stationary outer surface that defines in cooperation with the molding surface a pressure zone, and a resin source configured to introduce molten resin into the pressure zone to be forced into the molding cavities by pressure in the pressure zone. The molding surface is movable with respect to the pressure shoe to introduce molding cavities to the pressure zone to be filled with resin while the outer surface of the pressure shoe and the molding surface define in between an entrance gap of decreasing width upstream of the pressure zone. The outer surface of the pressure shoe is spaced from the molding surface in the pressure zone to define a minimum gap at which the outer surface of the pressure shoe has a slope parallel to the molding surface. The pressure shoe is adapted to be held in a flexed condition against resin in the pressure zone while forcing resin into the cavities, with the outer surface of the pressure shoe curved upstream of the pressure zone.

A material engagement element sheet formed from a sheet material (10) incorporates a pattern of material engagement element slots (14), each slot containing an array of material engagement elements (20) which have a tapered distal section (30), a flange section (34) and a proximal section (32) which is attached to an edge of the slots in the sheet material.. The material engagement element sheet material may be a single layer of shape memory material, or the sheet material may be a composite of different layers some of which may include pre-strained shape memory materials with distinguishable activation parameters. The material engagement element slot configuration allows for the simultaneous processing of the material engagement elements. The material engagement elements may be processed such that they are in a state that is substantially perpendicular to the surface of the material engagement element sheet. The configuration of the flexible base material and the pattern of the material engagement element slots may be used in order to manufacture various material engagement element devices including a material engagement element pad device (166), a cylindrical material engagement element device (104, 105), and a spherical material engagement element device (152).

Mold-in fastener products

Mold-in fastener products are made by forming a longitudinally continuous hook tape having a flexible base and an array of discrete male touch fastener elements extending from an upper surface of the base, forming a layer of flexible barrier material on the upper surface of the base, such that the male touch fastener elements are embedded in the layer of flexible barrier material, severing the flexible barrier material to form a pattern of patches of flexible barrier material spaced apart and surrounded by a continuous lattice of barrier material, stripping the lattice from the upper surface of the base to expose regions of the base between patches, and severing the hook tape along the exposed regions of the base to form individual mold-in fastener products, each having a patch of flexible barrier material surrounded by an exposed base edge region carrying male touch fastener elements.
