APPARATUS OF STALK KEEPING FOR HELICALLY COILED COUPLING ELEMENTS OF SLIDE FASTENER

摘要

A helical filament for teeth of sliding fastener is formed from straight filament rotated about its axis it is fed from supply. A sliding fastener continuous helical coil element is made by advancing and simultaneously rotating a plastic filament at the same rate and in the same direction as the filament is coiled. The apparatus preface comprises a filament store with a rotor rotatable in a bracket and a nonrotatable guide with an axial passageway and mounted coxially on the rotor.
