Abstract (en)
[origin: US4630340A] An apparatus and method for processing a warp sheet of synthetic multifilament yarns is disclosed, and wherein the yarns may be withdrawn from supply packages and advanced along a path of travel in warp sheet form, heated and drawn while in advancing warp sheet form to orient the filaments, and then wound, for example, on a warp beam. Upon detection of a yarn break, the advance of the warp sheet is terminated, and means are provided for interrupting the application of heat to the sheet while the advance is terminated so as to avoid damage to the remaining yarns from a continued application of heat.
