Abstract: A device (6) for holding and centering yam tubes (3) for processing while in a vertical orientation on transport disks (2), e.g., for removing a yam remnant (4) at a tube cleaning station. During such processing, the tubes are fixed in place by means of a height-displaceable centering arbor (12) coupled with a circuit arrangement which causes the operating height (h) of the centering arbor (12) to be automatically matched to the length of the respectively provided tube (3). An arresting arrangement (20) assure that the centering arbor (12) is securely fixed in place at each of its operating heights (h).

Abstract: An apparatus for pneumatically aspirating a yarn end from a spinning cop (15) with a suction nozzle (33) whose working position is adjustable has a housing (16) defining a vertical aspirating slit (19) over which a sealing belt (31) is disposed. An air passage (32) is formed in the belt (31) with the suction nozzle (33) fastened on the belt (31) about the passage (32). The belt (31) is selectively displaceable between a sealing position completely closing the aspirating slit (19) in the housing (16) and various aspirating positions wherein the air passage (32) of the belt (31) is in communication with the aspirating slit (19) of the housing (16) to apply suction through the nozzle (33) to initiate an effective, yet gentle loosening of a yarn end (46) from the conical windings (43) or the surface area of a spinning cop (41).

Abstract: 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.

Abstract: An apparatus for prepositioning a yarn end on a spinning cop for subsequent unwinding in a bobbin winding machine accomplishes improved functional capabilities by providing a positionally changeable yarn guiding device as well as a yarn retaining device. A part of the yarn guiding device which comes into contact with the yarn can be moved from an active position below the upper edge of the cop into an inactive position above the cop nose. The yarn retaining device has an opening for yarn entry. By way of a control device, the yarn guiding device is controlled to take up the inactive position following the placement of nose windings about the cop nose, and a device for inserting the remaining yarn end portion into the tubular interior of the cop is then activated and the yarn retaining device is taken out of contact with the upper edge of the cop. Preferably, the yarn inserting device comprises a tubular arbor which can be positioned centrally above the cop to function as a yarn end blower nozzle.

Abstract: A textile machine apparatus for handling tubes having remaining yarn thereon includes a branch path for supporting tube support members, which individually support tubes thereon, for travel to and from the discharge assembly of a textile winding machine.

A guide member is operatively connected to the discriminating sensor for guiding the tube support members supporting tubes having remaining yarn thereon onto the branch path for transport therealong to a tube stripping device, which strips the tubes of the remaining yarn. The stripped tubes are then returned to the discharge transport path at a location upstream of the discriminating sensor.
