Abstract (en)
[origin: EP2765102A2] The invention relates to a method and a device for distributing yarn wound on a cross-wound bobbin (2) at an operating unit of a textile machine, in which a yarn guide (3) actuated by a synchronous motor (43) reciprocates along the axis of the rotation of the wound bobbin (2), whereby on the synchronous motor (43) a time interval for the reciprocating travel of the yarn guide (3) from one dead centre (U1) to the other dead centre (U2) is set and the position of the yarn guide (3) is synchronized with the the reference position which is between these dead centres (U1, U2). During each reciprocating travel, the time point of the actual passing of the yarn guide (3) through the reference position is detected and the time difference between the time point of the actual passing of the yarn guide (3) through the reference position and the predetermined theoretical time point of the passing of the yarn guide (3) through the reference position is evaluated and, on the basis of the detected time difference, the duration of the rotation of the synchronous motor (43) changes until the respective reciprocating travel is finished, which also leads to the change of the length of the path of the yarn guide (3) from the reference position to the dead centre (U1, U2), to which the yarn guide (3) is currently approaching.
