Title:
MOLDED SURFACE FASTENER, MOLDED SURFACE FASTENER MANUFACTURING METHOD AND MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150493
Kind Code:
A1
Abstract:
Molded surface fasteners (1, 1a, 2, 3) according to the present invention comprise: a long base material part (10) in a first direction; and a plurality of engaging elements (20, 20a, 20b, 20c, 20d, 70) provided upright on the top surface of the base material part (10). The engaging elements (20, 20a, 20b, 20c, 20d, 70) each have a stem part (21, 21c, 21d, 71), and a hook part (31, 31b, 81) projecting from an upper end part of the stem part (21, 21c, 21d, 71) in a second direction. Each hook part (31, 31b, 81) has a shape which is tapered towards a hook tip end. The bottom surface of each hook part (31, 31b, 81) has a compression surface (32, 82) which is formed more smoothly than an upper end surface of the hook part (31, 31b, 81) through pressing compression by a cavity surface of a forming mold. Such a molded surface fastener (1, 1a, 2, 3) is novel and capable of providing high detachment strength with respect to loops of a female surface fastener, and capable of obtaining a good texture.
