<p>The invention is directed to apparatus for producing parallel cross filaments or threads consisting of two simultaneously rotatable wheels disposed at an angle to each other. The peripheries of the wheels are adjacent to each other at an single point while the peripheries diametrically opposite that point are spaced apart. Threads are fed from bobbins mounted on the wheels to thread outlets spaced around the wheel peripheries. Thread gripping means are positioned on the peripheries between the outlets, and the rotational phasing of the wheels is arranged so that, at the point where the wheel peripheries are adjacent, an outlet on the periphery of one wheel is directly opposite gripping means on the other wheel periphery. Actuating means are provided at the adjacent point and the gripping means are thereby actuated to grip a thread extending from an opposite outlet. As the wheels rotate, the thread gripped by the gripping means is drawn from the outlet to extend between the wheel peripheries. As each outlet moves in turn through the adjacent point with simultaneous rotation of the wheels, the threads are picked up and are drawn from the outlets to produce a series of parallel cross threads. Cutting blades are provided to sever the drawn out threads from the wheels.</p> |
