Method of joining a thread of a take-up coil in a spinning rotor of a spinning station of a rotor spinning machine having a normal travel course therethrough from the spinning rotor to the take-up coil for a thread that has spun therein and having a thread draw-off device and a thread guide disposed in the normal travel course, the joining being effected by means of a traveling joining device having a thread draw-off device for drawing off a thread end from the take-up coil and having a thread delivery device for transfering the drawn-off thread end to the spinning rotor of the spinning station, the method includes the steps of guiding a thread back from the take-up coil to the spinning rotor through the thread draw-off device of the joining device, that has been switched to reverse operation, and through the thread draw-off device of the spinning station that has been switched to idling operation, switching the thread draw-off device of the joining device to forward operation at an instant at which the thread is joined, switching on the thread draw-off device of the spinning station at an instant at which the thread draw-off devices of both the spinning station and the joining device are operating in synchronism, removing the thread from the thread draw-off device of the joining device by means of the thread delivering device and transfering the thread thereby, at a winding speed of the take-up coil that is increased over the normal winding speed thereof, to the normal travel course of the thread and to the thread guide in the spinning station against the action of a restoring force and device for performing the method.
摘要:
Method for controlling a thread joining process having several thread joining steps and occuring by starting a rotor of an open end rotor spinning machine, which includes choosing a narrow limited rotor speed range for the beginning of a starting process of a specific thread joining step, which occurs after a first thread joining step, and selectively starting and finishing thread joining steps in substantially constant given intervals before and after the beginning of the starting process, and an apparatus for carrying out the method.

A spool transporting assembly for the sequential transfer of textile spools wound on tubes, includes a spool preparation station having a support surface for textile spools, a spool receiving device, and a spool transporting device for transporting textile spools from the spool preparation station to the spool receiving device, the spool transporting device including a gripper head being movable in at least one plane into and out of a centered spool receiving position being fixed relative to the spool preparation station, the gripper head including gripper elements for gripping textile spools of different diameters in the centered spool receiving position.
摘要:
A joining device for joining a thread returned from a take-up coil to a spinning rotor of a rotor spinning machine by a thread regulator, the thread regulator having a thread clamp includes a roller pair, at least one of the rollers of the roller pair being drivable in direction in which the thread is returned.
摘要:
Device for controlling the contact pressure of a textile coil on a support or drive cylinder includes articulatingly suspended coil holder means for rotatably supporting the coil over the cylinder, a spring-loaded toggle-joint assembly being movable in a given plane into positions thereof wherein it is partly and fully extended, the toggle-joint assembly including a lever articulatingly connected to the coil holder means, and means for adjusting in the given plane the direction in which the toggle-joint assembly extends in the fully extended position thereof.
摘要:
An improved method for operating a textile machine having plural workstations comprising exchangeable components, each having a readable and writable transponder arranged on or integrated in the exchangeable components. During the lifecycle of the exchangeable components at least the operating data which influence the wearing of the exchangeable components are automatically stored on the respective transponder. Textile machines for carrying out the method are characterised by arranging in the region of each workstation at least one transceiver for writing and reading the transponders attached to or integrated in the exchangeable components.
摘要:
A fiber guide channel for pneumatic transport of individual fibers combed from a sliver by an opening cylinder of an open end spinning device for delivery to a spinning rotor. The fiber guide channel is arranged in a cover element for the rotor housing and the input side of the fiber guide channel is matched in its width to the mountings of the opening cylinder. The inlet and the outlet openings of the fiber guide channel have a slot-like shape and the maximum extension (B) of the inlet opening extends parallel to the axis of the opening cylinder. The maximum extension (L) of the outlet opening of the fiber guide channel is rotated about an imaginary center line of the fiber guide channel by 90°±15° relative to the maximum extension (B) of the inlet opening. The fiber guide channel has a substantially cylindrical zone Z, between the inlet and outlet openings, with the cross-section of the fiber guide channel constantly decreasing from the inlet opening to the zone Z.
摘要:
A tube transport assembly is provided for individually transporting tubes of the type onto which yarn is wound on a textile machine. The tube transport assembly includes magnetic components for guiding and transporting the tube support members along a transport path by magnetic interaction with ferromagnetic portions of the tube support members. The magnetic components can be configured as electromagnets or as permanent magnets. The transport path includes a junction at which the tube support members can be individually branched onto a branch path and a magnetic component is positioned adjacent the junction for selectively magnetically engaging the tube support members to guide the tube support members along to selected branch paths. A vertical transport component includes magnetically active carrier members mounted on an endless belt and is operable to magnetically engage and carry the tube support members vertically.

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.
