摘要： A device for searching for the yarn end on the conical windings of textile yarn cops increases the dependability of the detection of the position of the conical windings by providing a nozzle element in the yarn grasping mechanism for contacting the conical windings and whose position can be changed in relation to a sensor-controlled lifting mechanism. A sensor is arranged on the yarn grasping mechanism to detect a position change of the nozzle element relative to the lifting mechanism caused by contact of the nozzle element with the conical windings. The sensor is electrically connected with the drive of the lifting mechanism. The nozzle element, which advantageously is of a tubular bell-shaped configuration having a conical interior configuration, can be displaced coaxially to the longitudinal axis of the cop in an end of the yarn grasping mechanism which can be moved by the lifting mechanism. A marking, which can be easily recognized by the sensor, is placed on the displaceable nozzle element.
