发明名称 Process and an arrangement for picking up a yarn end of a spool package during a piecing operation
摘要 In a process and an arrangement for picking up a yarn end of a spool during piecing at a spinning unit which produces packages with double yarns which are used as feeding packages for a twisting operation, it is provided that, in the case of a yarn breakage, the winding-up and the spinning operation is interrupted in such a manner that the unbroken yarn of the double yarn is held in a yarn pick-up position, from which it is picked up during the piecing by means of a suction gripper which can be applied to the yarn pick-up position. After an unsuccessful piecing attempt, this suction gripper is applied to the circumference of the spool in order to still be able to take up the double yarn even then. In the event of a double yarn breakage, the suction gripper is movable to the circumference of the spool yarn seeking position, without first moving to the yarn pick-up position.
