摘要: Methods of forming mold cavities (1) suitable for hook and loop fastening (100), along with effective hook construction and hook and loop fastener products that have an ultrathin cross section (118). Photochemical techniques are employed to form plates (250) that define hook-form mold cavities (1), and, alternatively, chemical etching is employed following preforming of the cavities and machining. Included are hooks having three-dimensional tapers with enhanced loop engaging characteristics. By utilization of special surface finishes and tolerances, hook fasteners, having ultrathin cross sections (118) are realized, that pave the way for practical use of touch fasteners in a wide range of new areas.

摘要: A hook-type fastener product (10) for engaging loop elements is disclosed, having parallel rows of hooks (14, 40, 42) having differently constructed first and second sides (18, 16). The hooks are arranged such that, when engaged with loops, they resist disengagement from the loops more strongly when pulled in one sideways direction than when pulled in the opposite sideways direction. The product has a common base (12) from which the hooks, which are not limited to J-type hooks, extend. The first sides (18) of the hooks may be flat and the second sides (16) convex. Methods and an apparatus for producing the product are also disclosed.
