A cable spooling apparatus for use with a storage drum for spooling and storing cable. The cable spooling apparatus comprises a tensioning unit for adjusting the tension of a cable as it is being spooled onto the storage drum. The tensioning unit traverses a path between the opposite ends of the storage drum. Methods of spooling and unspooling cable using the apparatus are also disclosed.

A yarn accumulator unit for a workstation with a yarn guide arm pivotally mounted about a pivot axis, and a controllable drive unit for reversing pivoting of the yarn guide arm. The yarn guide arm is to be freely rotatably mounted and to have a magnetically acting first coupling element arranged at a distance from the pivot axis, and for the drive unit to have a second magnetic coupling element arranged so as to be adjustable transversely to the first coupling element or about the pivot axis, magnetically repulsively acting on the first coupling element, which second magnetic coupling element is arranged so that it can be brought into active connection with the first coupling element on the drive unit, in which case an adjustment of the second coupling element in the direction of the first coupling element causes a displacement of the first coupling element in the same direction.

A yarn tension control method includes a bobbin ascending or descending on sliding rails on a yarn carrier module. When the pattern is designed, the ascending or descending speed, time and distance of the fixing frame is calculated directly according to a yarn carrier stop, the quantity of redundant yarn and the speed of the carriage. When the carriage contacts a yarn carrier, a contact sensor feeds a signal back to the carriage, a signal emitter emits an instruction, and when a signal receiver receives the instruction, the fixing frame is controlled to ascend along the sliding rails. When the carriage drives the yarn carrier to enter a knitting area, needles are elected by a needle selection electromagnetic valve, knitting motion information is fed back to the carriage, the signal emitter emits an instruction, and when the signal receiver receives the instruction, the fixing frame is controlled to descend.

A ribbon self-orienting device that is to be interposed between the source and the target of a traveling ribbon, either during winding of a ribbon into a traversed roll or during pay-off of a ribbon from a traversed roll. A pivoting frame is pivotally coupled to a frame support, at a pivot axis. First and second direction changing means coupled to the pivoting frame serve to change the direction of the traveling ribbon. A force transfer means transfers a transversely directed force, imparted by the traveling ribbon due to the ribbon traversing its traversed roll while under tension, to the pivoting frame causing the pivoting frame to move about the pivot axis. Other embodiments are also described.

The present invention is an apparatus, system, and method for a low tension application spooler and or coiler system that positively drives the material into the coil and or reel so that the tension is minimum during the winding process.

A method of controlling a yarn compensating arm at a workstation of a spinning machine, wherein the yarn is initially withdrawn from an intermediate vacuum storage device. Before emptying the yarn from the storage device, the compensating arm is deflected past its working and into an out-of-the-working-range position, wherein the yarn is captured by the compensating arm and also deflected to the out-of-the-working-range position to form a non-working yarn reserve. The compensating arm is retained by a force at the out-of-the-working-range position while the yarn is emptied from the storage device. Upon being emptied from the intermediate vacuum storage device, the yarn exerts a tensile force on the compensating arm that overcomes the retaining force causing the compensating arm to return to its working range position.

Yarn delivery device for a twisting or cabling machine having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection.

An electromagnetic device for eliminating a yarn loop during winding of a yarn on a cross-wound bobbin on a spinning machine at a constant speed of the yarn production includes a cylindrical two pole magnet rotatably mounted about a longitudinal axis thereof. A compensatory arm is connected to the two pole magnet. A magnetic core includes two poles situated opposite of each other, with the cylindrical two pole magnet rotatable between the poles. A side of the magnetic core opposite from the two poles passes through a cavity of an electrical coil, wherein the magnetic core is interrupted in the cavity. A two pole permanent magnet is located at the point of the interruption of the magnetic core in the cavity of the electrical coil.
