<p>METHOD AND APPARATUS FOR FORMING A BASE FABRIC COMPOSED SOLELY OF LONGITUDINAL YARNS A method and apparatus for forming a base fabric composed solely of warp yarns to be used in making a papermaker's felt. A plurality of yarns are drawn from a supply and wound around a pair of parallel drive rolls in a helical pattern by a travelling winding member. Two sets of parallel guide tines project from each end of the winding member. The corresponding ends of a plurality of loops are attached to the trailing ends of the first set of tines and pass around the rolls and the opposite ends of the loops are attached to the leading ends of the second set of tines. The yarns to be wound are attached to the trailing ends of the second set of tines. As the rolls rotate, the winding member travels in an endless path around the rolls to draw the yarns from the supply and wind the yarns in a helical pattern. A comb is located parallel to the rolls and the tines pass through the teeth of the comb to maintain proper spacing and order of the yarns as they are wound.</p> |
