    摘要： Molding apparatus and method for molding of features integral with a base, such as in the production of fastener elements for hook-and-loop type touch fasteners, e.g. by the Fischer process, employs a mold roll (1) formed of rings (9) that have coolant passages (22) formed within the ring components (9) themselves for substantially direct contact with cooling liquid. Axial tie rods (16) compress the mold rings (9) together, contributing to the sealing of the coolant passages and the stiffness of the mold roll. Mold cavities (2), including cavities (2) used for injection molding, and cooling passages (22) formed in either mold rings (9) or injection mold plates by photo-chemical etching, laser machining and other techniques are disclosed. Various machines and methods taking unique advantage of these features are disclosed, including ring alignment methods for improved base thickness control and for forming products with very thin bases.

    摘要： A fastener strap sheet is provided that includes (a) a sheet material having a first surface and a second surface substantially opposite the first surface, the first surface being constructed for face-to-face cooperating engagement with the second surface; and (b) a pattern of cuts extending through the sheet material, the cuts defining an array of fastener straps, each fastener strap including an elongated body having a predetermined width, and a head portion at one end of the body having a width greater than the predetermined width and defining an opening through which the strap body can be pulled. The array of straps define a first set of straps and a second set of straps, the heads of the first set, being located on a first side of the array and the heads of the second set being located on a second, opposite side of the array, and the bodies of the first set being directly bordered by and parallel with the bodies of the second set, in an interdigitated arrangement.
