METHOD FOR MANUFACTURING HOOK-AND-LOOP FASTENER AND HOOK-AND-LOOP FASTENER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a hook-and-loop fastener which uses as few materials as possible other than a molding material.SOLUTION: A method for manufacturing a hook-and-loop fastener includes: an injection molding process for forming a molded article (1x) in which a column group (3x) that is an aggregation of a plurality of columns (31x) and a base plate (2) including a surface where the column group protrudes are integrated by injection molding; a cutting process for cutting a tip part of the column group to form a cut article (1y) in which a small column group (3y) shorter than the column group and the base plate are integrated; a melting process for melting a tip part of the small column group to form a column body part (31a) that is a non-melted part and an engaging part (31b) that is a melted part and is thicker than the column body part (31a) from each small column (31y) constituting the small column group; and a cooling process for cooling to define a shape of an engaging element (31) including the column body part and the engaging part and to form a hook-and-loop fastener (1) in which an engaging element group (3) that is an aggregation of a plurality of the engaging elements and the base plate are integrated.SELECTED DRAWING: Figure 1
