摘要： Drawing frame for drawing fiber sliver with draw frame rollers comprising a pair of pre-drawing rollers and a main drawing roller pair. Power transmission members in the form of flat belts are used for driving the draw frame rollers. A deflection pulley engages the flat belts between respective pairs of wheels deflecting the belts for increasing the angle that the flat belt extends around the respective wheels to provide a non-slip engagement between the flat belts and the respective wheels.

摘要： To piece with a spinning device having a pneumatic twisting unit, a yarn end is back-fed from an output side, through the twisting unit, to drawing equipment, and then inserted laterally into a pair of drawing unit output rollers, from where it is drawn off through the twisting unit in the form of a continuous yarn with a rove being incorporated into it. During the back-feeding of the yarn end to the twisting unit input side, the yarn end is conveyed to a grasping device located at the side of the drawing equipment. The grasping device pulls the yarn end for subsequent insertion into the pair of output rollers past such rollers until such end is alongside the drawing equipment. A yarn presenting device is provided to convey to the grasping device the yarn end leaving the twisting unit input side. The yarn presenting device includes a compressed air nozzle oriented essentially parallel to the nip of the pair of output rollers, the outlet of which is located on a side of the twisting unit across from the grasping device and which outlet is also oriented towards the grasping device to convey the yarn end thereto.

摘要： Transmission of the thread twist-forming force to the thread end is facilitated by a finger mounted eccentrically in the bore of the thread drawoff tube. The thread, which is rotated about the circumference of the bore, periodically engages the finger, which finger plucks the thread away from the tube wall and momentarily relieves the bearing force between the thread and the drawoff tube at the tube infeed end. The finger is spaced inwardly from the tube infeed end and may be a pin projecting radially inward from the tube wall or an offset wire extending parallel to but eccentrically of the tube axis.

摘要： A supporting-disk bearing, particularly for the shaft of an open-end spinning rotor, the shaft (1) being mounted in a wedge-shaped gap formed by supporting disks (4, 5), and the supporting disks (4, 5) having a running surface (40,50) consisting of an elastic covering against which the shaft (1) is pressed. The running surface (40,50) has at least one interruption formed by a recess and bridged by the line of contact of the shaft (1). The recess can be designed in various ways, but it is preferably groove-shaped. The wear of the running surface is reduced as a result of this design.

摘要： In a device for the piecing of a yarn on an open-end spinning device, a yarn mover by means of which a yarn end is fed to a yarn draw-off pipe is provided. A first stop to determine the cutting position and a second stop to determine the yarn insertion position are assigned to the yarn mover. The first stop can be put out of action. In addition, a yarn length adjusting device is provided to determine the length of yarn to be fed back into the open-end spinning element. The cutting position and the yarn insertion position of the yarn mover are set for the smallest size fiber collection surface of the open-end spinning element that can be used. When larger fiber collection surfaces are used, the additional required length of yarn is readied by rotating the winding device backward.

摘要： A process for replacing a full wound bobbin on a bobbin winding machine with an empty bobbin support, wherein the yarn is wound onto the bobbin support in a bobbin winding zone by a traversing yarn guide. The process includes moving the traversing yarn guide out of the winding zone when the bobbin is completed, and into a cutting and clamping zone for severing the yarn. The yarn continues to be fed by the spinning machine, and will be collected by a suction pipe while the full bobbin is being replaced by an empty support. The suction pipe moves the yarn into a position to be clamped and cut by a cutting and clamping device, which rotates with the support for the bobbin. The yarn is guided to wind a reserve onto the end of the bobbin support before moving the yarn back into the winding zone to be wound by the traversing means onto the empty bobbin support.The invention also includes a device for carrying out the process of the invention. This device comprises a traversing yarn guide which is detachably connected to the yarn traversing means by a permanent magnet. When the full bobbin is completed, means are provided for detaching the yarn traversing guide from the yarn traversing means, and to move it into the cutting and clamping zone.

摘要： A device for the control of an open-end spinning element, including a pivoted control lever (4) is provided which is capable of assuming three different working positions. In a production position the control lever brings a first drive, running at production speed, into driving contact in the operation of the open-end spinning element. In a braking position the control lever brings a brake to act upon the spinning element. The control lever in a piecing position brings a second drive which runs at a lower speed than the first drive into driving contact with the open-end spinning element. At least the positions determining the production and the piecing position of the control lever are provided with a common control element, capable of being moved back and forth in the direction of movement of the free end of the control lever between at least two switching positions. The control element is provided with a stop element which determines at least the production or the piecing position of the control lever, depending upon the switching position (I, II) of the control element. The stop element is an integral part of the control element. The control element, in addition to movement in the direction of movement of the free end of the control lever, can also be moved transversely to the direction of movement of the free end of the control lever.
