Flächenhaftverschluss sowie Verfahren und Vorrichtung zu dessen Herstellung

摘要

A molded surface fastener is manufactured by supplying molten resin (4) to the circumferential surface of a die wheel (2) rotating in one way to mold a substrate sheet blank (4a) and a multiplicity of substantially straight and inclined engaging element blanks (4b) in an integral form, and then pressing distal ends of the engaging element blanks (4b) by a heat-molding roller (9) in rotation at the same speed to incline the engaging element blanks (4b) further toward the substrate sheet blank 4a and also to melt the distal ends to shape each said distal end into an engaging head (12b) projecting in a direction opposite to the direction of inclination of the respective engaging element blank (4b). Each of the resulting engaging elements (12) is composed of a stem (12a) rising from the substrate sheet surface with inclination by a predetermined angle (θ1), and an engaging head (12b) projecting from an upper end of the stem (12a) in a direction opposite to the direction of inclination of the stem (12a), an extension line of the engaging head (12b) crossing the substrate sheet surface at a predetermined acute angle (θ2).
