VERFAHREN ZUR HERSTELLUNG EINES BANDES MIT HAFTVERSCHLUSSELEMENTEN AUF DER OBERFLAECHE.

摘要

A tape having a series of surface-type fastener pieces is manufactured by intermittently feeding a surface-type fastener tape blank composed of a release sheet of paper and a surface-type fastener of synthetic resin attached by an adhesive layer to the release sheet and comprising a base strip and a plurality of fastening elements, and fusing the surface-type fastener in a predetermined pattern by ultrasonic or high-frequency welding to produce gaps which define a series of surface-type fastener pieces on the release sheet. The release sheet with the series of surface-type fastener pieces attached thereto by the adhesive layer is then separated from a scrap composed of a surface-type fastener web from which the surface-type fastener pieces have been blanked out. Each of the surface-type fastener pieces is fused along its peripheral edge to prevent the fastening elements thereon from unraveling.
