ABSTRACT:
An apparatus for applying weft yarns in a cross direction to warp yarns having an adhesive scrim thereon includes the warp yarns on 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. The warp yarns are fed upstream from a spool along a rotating tube on which they are mounted and pass through a tensioning apparatus to unify the tension in the various yarns running along the tube. The uniformly tensioned weft yarns pass through individual nozzles around the circumference of the rotating tube where the yarns are deposited onto the adhesive scrim. After the weft yarns are deposited on the warp yarns, the transfer belt moves the fabric having warp and weft yarns across a cooling section of a mandrel where the adhesive is set.
