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.

Device for locating a free end of yarn wound on a cop

A pallet transport system for a textile cheese winding machine includes a cop delivery and storage track for supplying cops to be rewound, an empty tube return track, and a plurality of transport tracks each extending through one winding head of the bobbin winder transversely between the supply and return tracks. The entrance region of each transverse transport track is closable by selectively operable blocking mechanism disposed in operation to permit empty pallets to enter the transverse transport track while pallets equipped with cops are shunted. In this manner, the transverse transport tracks serve as a storage device for empty pallets which provides the advantage that, at the completion of a batch, the time needed by the bobbin winder to properly end the batch is shortened, and hence the machine's efficiency is increased.

Pallet transport system for a cheese-producing textile machine

A conveyor apparatus has mutually independent pallets carrying bobbins or bobbin tubes and having base plates. A moving surface, such as a surface of a conveyor belt, imparts a slaving force to the base plates standing on the moving surface and slaves the base plates along a conveyor route by friction. A device acts upon unmoving pallets for briefly varying the slaving force of the moving surface.

Conveyor apparatus for mutually independent pallets that carry bobbins

A textile winding machine is provided having an operator accommodating package readying assembly on which individual tube support members are supported at a convenient height to thereby provide an operator with ready access to the tubes or yarn packages supported on the tube support members. The textile winding machine includes a common exit path component along which tube support members are transported after unwinding of the feed packages supported thereon at the winding units of the textile winding machine and an entry conveyor device for raising the tube support members in spaced apart manner from the common exit path component with the tubes or yarn packages out of interference with one another to a feed package re-supply support assembly extending longitudinally along the textile winding machine at a height generally at the waist level of an average operator. During regular re-supply rounds, for example, an operator can conveniently transfer fresh feed packages from a rolling container or other storage device to the empty tube support members supported at waist level and the operator can manually prepare the yarn ends of any partial feed packages as well. A return conveyor allows recirculation of tube support members in a closed loop.

An automatic yarn winding apparatus includes plural aligned winding stations and a delivery conveyor extending along the winding stations for supplying thereto yarn packages comprising yarn tube support members carrying fully wound yarn tubes. The delivery conveyor is driven alternately in opposite directions. Package entrance conveyors supply yarn packages to the delivery conveyor at least two spaced locations therealong. Switchable mechanisms are provided for selectively forming and removing at least one package barrier along the delivery conveyor between the entrance locations for preventing package movement therebeyond. By provision of additional package entrance conveyors and package barrier mechanisms, the delivery conveyor can be effectively divided into multiple transport sections for respectively supplying differing groups of the winding stations with differing respective groups of yarn packages.

Package delivery arrangement for automatic yarn winding apparatus

A reserve winding of yarn on a tube on which a cross-wound package is built. The reserve includes an end projecting from the windings and extending to provide an initial length along the surface of the tube and around which windings are formed without substantial overlapping with the windings progressing from the inward extent of the initial length of yarn toward the tube end. The reserve winding is formed by a method utilizing an apparatus that is part of a traveling service unit and includes a suction conduit centrally located in a tube clamping plate for drawing-in the end of yarn and yarn guiding and advancing elements that guide the yarn inwardly along the surface of the tube and then advance the yarn outwardly during rotation of the tube to form the non-overlapping windings. The drawn-in end of the yarn is then cut at a maximum of approximately one centimeter from the windings or is inserted into the interior of the tube.
