摘要： An open-end rotor spinning machine which operates at rotor speeds higher than 100,000 rpm is constructed so that the critical system rotational speed is higher than the 100,000 rpm operating rotational speed. The rotatable rotor has a shaft bearingly supported in the nip between at least two pairs of supporting disks. Each disk has a plastic outer covering around the circumferential surface thereof and preferably is provided with at least one recess along its circumference. An elastic support surface preferably covers the circumference of each disk and is disposed between the disk and its outer plastic covering. The interior distance between the disks is from 20 to 69 mm. A circumferential recess preferably is disposed in at least on of the lateral surfaces of the plastic covering of each supporting disk. An electric motor drives a drive pulley, and the two are mounted in a stationary mounting while a swivellable pillow block moves the shaft to press against the drive pulley for driving the shaft and rotating the rotor. The center of gravity of the spinning rotor is at a distance of from 15 to 28 mm in front of the closest of the two pairs of supporting disks to the rotor. The free end of the rotor bears against an axial bearing and extends from 5 to 30 mm beyond the pair of supporting disks farthest away from the rotor and in the direction of the axial bearing.

摘要： In an open-end spinning device with a spinning rotor a compressed air conduit is provided for directing an air current upon the inner surface of the spinning rotor. This compressed air conduit is connected through a stop valve to a source of compressed air. The compressed air conduit is provided with a pressure control device which can be pre-set to at least two pressure levels. The pressure control device has parallel conduits of which one conduit is provided with a pressure reduction device for the low pressure.During the preparation of the piecing operation, compressed air, at high pressure, is fed into the spinning rotor to clean said spinning rotor. Subsequently, but before the start of fiber feeding into the spinning rotor, the compressed air is reduced to a lower pressure value and is finally switched off before the yarn is fed back into the spinning rotor.The invention includes the process for restarting the open-end spinning device. Both the process and the device may be manually or automatically operated.

摘要： An apparatus and method for stopping operation of an open-end spinning machine is disclosed whereby the rotor shaft 1 of the spinning rotor and the shafts 30, 40 of the support rollers 3, 4 are rapidly but gently stopped by applying a braking force to the shafts of the support rollers after the rotor shaft is braked. Preferably a single force is shared and applied in timed sequence for braking the rotor shaft and the support roller shafts. The apparatus for carrying out the method includes a pivotable lever 7 which is pivotable about an axis 70 and carries a support 73 having a brake lining which receives the rotor shaft 1. A belt lifting roller 72 is carried on the pivotable lever which lifts a tangential belt 5 off of the rotor shaft 1 to thus stop the drive of the spinning rotor. The support 73 is elastically carried on the lever 7 by means of a U-shaped spring 74. A pair of brake jaws 80, 81 are carried on a common mounting piece 8 about a fulcrum 80 which can be pressed against the shafts 30, 40 of the support rollers 3, 4 after the shaft 1 has been pressed onto a stop 6 by means of engagement with the support and brake 73. Good guiding of the support 73 and uniform seating of its brake lining on the shaft 1 is achieved by the U-shaped configuration of spring 74. The common mounting 8 of the brake jaws moves in a pendulum fashion on the lever 7 whereby the brake jaws are self-centering and exert a uniform pressure on the shafts of the support rollers.

摘要： A winding apparatus including a winding roll driving a bobbin and a yarn reservoir arranged between a yarn supply point and the winding roll. The state of filling of the reservoir is monitored by a monitoring device which generates a signal for controlling the speed of the winding roll. Interposed between a driven drive shaft and the winding roll are a pair of intermediate wheels which are selectively brought into engagement with the drive shaft and the winding roll responsive to predetermined states of filling of yarn on the reservoir that is sensed by the monitoring device so as to either drive the winding roll at speed higher or lower than the delivery speed at the yarn delivery point. A brake lever is operably connected to a mechanism which supports the intermediate wheels and is brought into contact with the winding roll when both the intermediate wheels are out of engagement with the shaft and winding roll for stopping the winding roll.

摘要： The present invention relates to a bearing for an open-end spinning rotor. The latter is driven at its rotor shaft by means of a tangential belt in a predetermined direction and is supported in a nip which is formed by at least two bearing disks capable of being driven by the rotor shaft. A bearing disk (at least one) leads in relation to the drive direction of the tangential belt rotating into the nip, and another bearing disk (at least one) trails in relation to the drive direction of the tangential belt rotating out of the nip. The axis of the bearing disk (at least one) rotating into the nip is at a specified distance from the plane which goes through the rotor shafts of the spinning rotors of several adjoining open-end spinning devices. This distance is being smaller than the distance between the axis of the bearing disk (at least one) rotating out of the nip and the rotor shaft plane. A plane going through the axes of the bearing disks forms an acute angle between 5° and 15° with the plane going through the axes of the spinning rotors.
