    摘要： Hook structures (10) for use in hook and loop or hook and engagement material fastening applications. Structures according to embodiments of the invention include hooks (16) which extend from bases (12) which in turn extend from a foundation and also extend laterally across the structures. The bases (12) are separated by valleys (39) which also extend laterally across the structures, whose height can be uniform laterally in the structures or varied. The bases (12) provide suitable strength and support to allow the hooks (16) to be robust and strong for permanent or semi-permanent fastening applications, while the valleys (39) interposed between bases (12) allow the hooks (16) to penetrate sufficiently deeply into the engagement material for effective fastening to occur. Such structures may be formed according to processes which physically or conceptually employ various layers to support hooks (16), retention barrier members such as fingers (32) interposed laterally between hooks (16), and/or for spacing such hooks (16) and barriers as desired. Accordingly, structures can be formed according to the present invention using conventional ring-molding techniques (or any other desired techniques), to provide hook fasteners with excellent fastening strength and other desired properties typically required, for example, in semi-permanent or permanent fastening applications.

    摘要： A method of manufacturing a surface fastener (1) according to the present invention includes a molding step of molding a pre-fastener body (40) and a stretching step of obtaining the surface fastener (1) by stretching the pre-fastener body (40) in a machine direction (MD) by a stretching device (80), the stretching device (80) including at least a first heating roller (83), a second heating roller (84), and a stretching roller (85) that heat the pre-fastener body (40), the stretching roller (85) being configured to rotate at a faster rotational speed than the second heating roller (84). The stretching step includes heating the tentative base portion (10a) of the pre-fastener body (40) with the tentative base portion (10a) being in contact with the first heating roller (83); heating engagement elements (20) of the pre-fastener body (40) with the engagement elements (20) being in contact with the second heating roller (84); and setting a heating temperature of the second heating roller (84) to be lower than a heating temperature of the first heating roller (83). Consequently, the surface fastener (1) can be manufactured while lowering of the engagement elements (20) and thinning of the base portion (10) are suppressed or prevented.
