METHOD FOR ELIMINATING A LOOP OF YARN WHEN WINDING YARN ON A CROSS-WOUND BOBBIN ON A SPINNING MACHINE AT A CONSTANT SPEED OF THE YARN BEING PRODUCED AND A DEVICE FOR PERFORMING IT

摘要

The invention relates to a method and a device for eliminating a yarn (0) loop when winding yarn (0) on a cross-wound bobbin (A2) on a spinning machine at a constant speed of the yarn (0) being produced, in which the length of the working path of the yarn (0) varies in the space between a draw-off mechanism (1) of yarn (0) and a winding device (A) of yarn (0) by deflecting the yarn (0) by a capturing and guiding means (7) of a movable compensatory arm (6). The yarn (0) is acted upon in a controlled manner by the capturing and guiding means (7), which is deflected by a reversible two-way controlled means (4), whereby the position and/or direction and/or speed and/or force applied by the reversible two-way controlled means(4) according to the operation which is being carried out at the operating unit.
