摘要： A pot spinning machine holds a yarn rewinding tube in ready position during the spinning operation for immediate movement to an operative rewinding position in the event of a yarn break so that the broken end of yarn is not lost by winding onto the yarn cake already formed in the spinning pot and the yarn cake may then be properly rewound. The yarn break is detected with the aid of a yarn sensor which then emits a signal for immediately moving the rewinding tube into the rewinding position and clamping the yarn end. The rewinding operation can begin, even in the absence of a loose end of the yarn, if the yarn has assumed the form of a chord-like yarn segment extending substantially in the circumferential direction against the inner face of the yarn cake deposited onto the inside wall of the pot, which can be grasped and utilized to initiate the rewinding operation.

摘要： A pot-spinning machine is equipped with a rewinding tube mounted on each yarn guide and with a central, common shogging drive of the yarn guides at one side of the machine. After a yarn break or similar interruption in spinning, in order to be able to initiate the rewinding operation immediately at the affected spinning station while simultaneously continuing the spinning process unchanged at the neighboring spinning stations, the shogging motion of the yarn guide is separated from the motion of the rewinding tube supported on the yarn guide, so that the rewinding tube is then moved only at the forward indexing speed of the yarn guide which is relatively slow compared with the shogging speed and which does not affect the rewinding of yarn onto the rewinding tube.

摘要： A method for rewinding a spinning cake from a spinning pot of a pot spinning apparatus onto a rewinding body, preferably onto a tube as a yarn carrier, includes drawing a sliver to be spun in a drafting configuration, guiding the sliver in a pneumatic piecing aid, and depositing the sliver with a traversing yarn guide onto an inner wall surface of the rotating spinning pot as the spinning cake, while maintaining a requisite rotation for formation of a yarn. A yarn guide is moved toward the middle of the spinning cake in a last stroke being shorter than a next-to-last stroke of the yarn guide toward the middle of the spinning cake, once a predetermined size of the spinning cake is reached, before initiating rewinding of the spinning cake onto the rewinding body. A delivery of the sliver from the drafting configuration is stopped once a reversing point of the stroke is reached. The rewinding body is introduced into the spinning pot and the yarn is transferred onto the rewinding body. The rewinding body is raised into a rewinding position. A piece of yarn extending from a tube tip of the rewinding body to the spinning cake in the last yarn guide stroke is wound onto the rewinding body, and the piece of yarn is covered with subsequently wound-on yarn layers.

摘要： A method and a device for initiating the rewinding process after a yarn break in single stage pot spinning. In the process, a yarn detaching device (14) is introduced into a spinning centrifuge (3) rotating a high rpm, and places a cutting edge (16, 48) against the conically wound portion (32) of a spinning cake (15) deposited on the inner wall (26) of the spinning centrifuge (3). The yarn detaching device (14) has a yarn guide device, whose yarn guide contour (17, 43) covers the cutting edge (16, 48) of the yarn detaching device (14) such that in the course of the initiation of the rewinding process lower winding layers of the conically wound portion (32) are lifted on the rewinding tube (9) and in this way dependably prevents the winding of yarn around the yarn detaching device (14) during the rewinding process.

摘要： A pot spinning method and apparatus wherein a spinning pot rotates during spinning about a vertical axis while an associated yarn guide tube delivers fiber material through an exit mouth of the yarn guide tube onto the rotating inside surface of the spinning pot in the form of a revolving extent of the yarn which also rotates about the axis of the spinning pot. A yarn break or unacceptable changes in quality of the spun yarn can be ascertained extraordinarily quickly if deviations in the duration of the revolution of the yarn extent at the mouth of the yarn guide tube are monitored.

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.
