WOVEN TAPE WITH LOCALIZED TIGHTENED PARTS WOVEN ON AN AUTOMATIC SICKLE LOOM, PROCESS AND DEVICE FOR CARRYING OUT THIS PROCESS

摘要

The invention concerns woven straps having transverse contractions, as well as a method and apparatus for their manufacture. Contractions are formed along straps having a continuous unchanging weave and continuous selvedge by altering spacing of warp yarns during weaving. The warp yarns are spaced by a V or fan shaped support which is vertically movable to cause corresponding width variations in the straps.
