Title: Method of making a woven zipper

Abstract: A method of making a woven zipper is disclosed, and an apparatus for carrying out the method. A zipper tape is woven from warp threads and weft threads. A coil-forming filament is advanced longitudinally of the weft threads and additionally is made to perform a movement about the surface of an imaginary cone whose base extends transverse to the longitudinal advancement of the filament. Cover threads, extending lengthwise of the weft threads are stepwise moved to the vicinity of the imaginary surface and held until the filament has passed them; thereupon, they are moved through the surface to the interior of the cone and a binding thread is passed behind them in longitudinal direction of the weft threads.
