VERFAHREN UND VORRICHTUNG, UM EINEN HINUEBERGREIFENDEN STREIFEN AN DAS UNTERE ENDE EINES REISSVERSCHLUSSES ANZUBRINGEN.

摘要

In a method and apparatus for applying a protective strip by sewing to an end of a slide fastener, a continuous protective strip (9) is fed downwardly toward a tape supply position on the base (7) of a sewing machine (SM) with its one surface facing opposite to a direction of feed of a slide fastener until a leading end portion of the protective tape (9) overlays the base (7) by a predetermined length, then the leading end portion is bent in a direction opposite to the fastener feed direction by a stream of pressurised air issued from an air nozzle (48), thereafter, a slide fastener is advanced along the base (7) until its leading end reaches to a sewing position (X) located downstream of the tape supply position, thereby causing the leading end portion of the protective tape (9) to bend into a U-shape extending from the back to the face of the slide fastener around the leading end thereof, then the U-shaped leading end portion is cut from the continuous protective tape (9), thereby forming a U-shaped protective strip which in turn is sewn to the leading end of the slide fastener.
