摘要:
A spinning machine includes a plurality of work stations arranged side by side between two front-side ends along at least one longitudinal side of the spinning machine. Each work station has a draw-off device, and an individual drive for the draw-off device. Each work station further includes additional driven work elements for production and winding of a yarn, the additional work elements including at least a feed device, a spinning chamber, and a winding device. A suction device generates negative pressure at the work stations and includes at least one negative pressure source and at least two negative pressure channels. Each of the negative pressure channels extends in a longitudinal direction of the spinning machine only over one part of the work stations.

A method is provided for controlling movement and operation of an attending device of a yarn manufacturing textile machine, wherein the attending device moves along a row of workstations arranged next to each other to perform operations at the workstations. The method controls the movement of the attending device along the work stations and operations of the attending device based on success statistics of the operations at the workstations to achieve an overall increased efficiency of the textile machine. An operational stay of the attending device at a particular one of the work stations is terminated without waiting for a result of the operation being performed by the attending device at the particular workstation.

In a flyer-type textile spinning machine, spinning elements, such as the flyers or the bobbins or both, are driven by plural drive motors affixed at spacings to the rail supporting the spinning elements, each drive motor directly driving synchronously at least one spinning element via a timing belt, with the remaining spinning elements being synchronously driven, in turn, from the directly driven spinning elements via a series of like timing belts.

For compensation of changes in rotational speeds, for example, occurring because of varying loads on the motors, the drive mechanisms for at least two kinds of working units have a common synchronizing mechanism and are connected operably by a torque transfer device. The torque transfer device comprises, for example, a drive belt and two drive pulleys, each of which is attached to a different drive mechanism. The common synchronizing mechanism can comprise either a common rotational speed control or an adjustable current supply for the motors of the drive mechanisms.

The invention relates to a method of and a system for controlling the operation of open-end spinning machines comprising a plurality of spinning units, which method is based upon a permanent cyclic communication of a central unit of the system with the individual spinning units. According to the invention, at a given instant, a single spinning unit only is connected to the central unit of the control system, said central unit being supplied with information data about the condition of the spinning unit connected thereto while said central unit simultaneously transmits instructions for said spinning unit, the other spinning units operating automatically on the basis of the stored instruction the validity of which lasts for the time of one control cycle.

In a ring-type spinning or twisting frame in which the ring stator and the rotor are coupled to one another with rolling members inserted therebetween in grooves formed facing each other in the rotor and the stator, braking means being provided between the stator and the rotor, the improvement is disclosed according to which an annular bracket is provided beneath the annular cage, the seats for the rolling members having appropriately sloping edges, so that when the spinning frame starts its rotation, the annular cage is lifted, whereas the contrary occurs when the spindles are stopped, so that the cage is allowed to fall due to its own weight and the rotor is stopped instantaneously.

An open end spinning device or a false twisting device having two mutually parallel pairs of rollers for driving a spinning rotor or a twisting tube and a horseshoe-shaped magnet associated therewith for retaining the twisting tube or rotor in a wedge-shaped nip between the pairs of roller, each pole of the magnet acting on a collar on the rotor or twisting tube and being provided with a recess extending parallel to the axis of rotation of the rotor or tube and having a semi-circular cross-section to receive the collar is provided with a magnet having one pole shaped so that upon axially displacement of the rotor or tube away from its normal position by pull of the thread each of the collars still lies opposite the magnet at least at the base thereof.

Method and apparatus for the rejoinder of a broken thread in an open end spinning unit. The thread is formed from fibers fed to a rotating spinning turbine and withdrawn therefrom to a winding device. The continuity of the withdrawn thread is sensed and a signal provided on interruption thereof. A control mechanism responsive to the signal is provided for establishing a predetermined sequence of operation of said spinning unit for rejoining the thread. The turbine is movably mounted, so that the control unit on receipt of a signal first shifts the turbine from a working position into a position where spinning is arrested and to thereafter initiate the rejoinder operation and maintain the operation for a predetermined time interval to complete said sequence. The control mechanism may be provided for individual or a plurality of units. Other sensing means monitoring the operation of the turbine are included.
