ABSTRACT:
An apparatus for applying weft yarns in a cross direction to warp yarns assembled on a beam in parallel aligned relationship and having an adhesive scrim thereon includes a supply roll of the warp yarns on such a beam which are fed downstream of the apparatus by first laying the warp yarns onto a transfer belt to reduce the tension in the yarns and controlling them for application of the weft yarns. A transfer belt and warp yarns are first folded between folding bars into a cylindrical configuration where they are formed around the perimeter of an elongated mandrel having a heated section at its upstream end and a cooling section at its downstream end. Weft yarns are wrapped around the warp yarns and the supporting transfer belt within a rotating tube having a plurality of longitudinally and circumferentially spaced spools of weft yarn disposed on its outer surface.
