Abstract:
1. An apparatus for winding a roving onto a roving bobbin, comprising: a twist-generating device, and a pair of take-off rollers downstream of said twist-generating device; a bobbin mounting configured for rotation of a roving bobbin; a roving laying device configured for laying the roving onto said roving bobbin; said take-off rollers disposed upstream of said roving laying device; said roving laying device further comprising a pair of winding delivery rollers with at least one of said winding delivery rollers being a driven roller, said winding delivery rollers disposed directly adjacent to said roving bobbin and defining a nip line through which the roving travels as it traverses along an axial direction of said roving bobbin as the roving is wound onto said roving bobbin, said winding delivery rollers; and wherein rotational speed of said winding delivery rollers is regulated to achieve a controlled specific tension in the roving laid on said roving bobbin.
