Abstract:
An apparatus for fabricating a nonwoven fabric having the appearance of a woven fabric includes a supply station for parallel warp yarns, a support structure for orienting the parallel warp yarns into a cylindrical orientation, a weft yarn applicator for wrapping weft yarns around the cylindrically oriented warp yarns after an adhesive scrim has been overlaid onto the warp yarns, a heating station for activating the adhesive and a cooling station for setting the adhesive, and a cutter for severing the cylindrically formed fabric laminate so that it can be flattened and wrapped onto a take-up roller. A warp yarn alignment station includes two sets of rollers spaced apart to allow the warp yarns to pass between the two sets of rollers, wherein the of rollers are over-driven to provide a roller surface speed greater than a predetermined speed of the warp yarns.
