Abstract (en)

[origin: EP0419827A2] For eliminating yarn faults on a winding station (12), as regards yarn faults formed by a thickening, a distinction is made, with reference to their length, between shorter yarn faults caused by the spinning operation and longer yarn faults caused as a result of a piecing operation by means of an auxiliary thread. The electronic control unit (18) of the slub catcher (10) used is so designed that, in the event of yarn faults caused by a piecing operation, the severing operation is delayed in each case in such a way that there is no severance of the auxiliary thread. <IMAGE>
