<p>Arrangement when winding yarn (3) from a supply roll (2) by means of a flyer (4) onto a bunch of wires fed through the centre hole of the supply roll for automatically transferring to unwinding a new supply roll (2') when the yarn on the first supply roll (2) is used up or broken. According to the invention the new supply roll (2') is disposed downstream of the first supply roll (2) seen in the direction of feeding (a) of the bunch of wires and a second flyer (4') is associated with it. Downstream of the new supply roll (2') and the second flyer (4') there is according to the invention a holding device (13) to loosely hold the free end of the yarn (3') on the new supply roll (2') as long as the yarn (3) on the old supply roll (2) is not used up or broken. At its free end the yarn (3') on the new supply roll (2') is formed into a sliding knot (15) carried by the holding device (13), through which sliding knot the bunch of wires (1) is freely fed. To bring the second flyer (4) to rotate when the yarn (3) on the first supply roll (2) is either used up or broken there are means (6', 7', 8', 9', 10). According to the invention the holding device (13) is furtherore adapted to release the sliding knot (15) and to have it tightened around the bunch of wires (1) when the second flyer (4') starts to rotate and after that to release the free end (18) of the new yarn (3') as a consequence of the continued feeding of the bunch of wires (1).</p> |
