<p>When a full bobbin signal from a counter CCM counting the number of rotations of the front roller 3 is output, the control means 28 outputs a signal directed to the control motor M2 of a unit 29 for reciprocating a bobbin rail 10. As a result, the rotation of the control motor M2 is combined with the rotation of a differential gear 14 connected to the main motor M1, so that a reciprocating movement of the bobbin rail 10 after the full bobbin state is obtained which is faster than that obtained during a usual taking up operation of the roving, which causes the roving to be wouNd on the bobbin in a much coarser state than usual. A limit switch LSP detects a predetermined desired position of the bobbin rail 10, and the control means 28 outputs a signal directed to the unit 29, whereby the main motor M1 and the control motor M2 are stopped. <IMAGE></p> |
