摘要： A spinning machine and method separate a sliver delivered out of a sliver can at a spinning station of the spinning machine. The sliver is delivered out of the sliver can with a supply device at the spinning station in a delivery direction to a spinning device, and is guided by a sliver guide between the sliver can and the supply device. The sliver is clamped in the supply device at the spinning station. In order to separate the sliver, the supply device is driven counter to the delivery direction, wherein the sliver is returned by the supply device and, as a result, the clamping of the sliver in the supply device is released.

摘要： A spinning machine includes a plurality of adjacently arranged spinning stations, wherein carrier devices for a fiber bundle are assigned to the spinning stations. Each spinning station operating with a fiber bundle feed device and a fiber bundle piecing device. The fiber bundle piecing device includes a sliver pickup configured to grasp and pick up a leading end of the fiber bundle from the carrier device and a supply device configured to move the leading end of the fiber bundle to the feed device. The piecing device with the sliver pickup and the supply device is at a fixed stationary position relative to the spinning stations and is assigned to a single spinning station or a group of spinning stations.

摘要： A sliver piecing unit 80 includes three sets of separable rollers 804 and 844, 806 and 846, and 808 and 848 for nipping a sliver S1 fed from a consumed can to a spinning machine. A throttling nozzle 870 is arranged between the second and third sets of rollers 806 and 846, and 808 and 848. The draft ratio between the first and second sets of rollers 804 and 844, and 806 and 846 can be varied between 1.0 and 2.0. A sliver feed unit 70 includes a separable first and second roller 702a and 702b for feeding a sliver S2 from a full can to the piecing unit 80 so that the slivers S1 and S2 are combined. The draft ratio between the first and second sets of rollers 804 and 844, and 806 and 846 is controlled to obtain combined slivers of a thickness corresponding to that of a single sliver. A nipping belt 884 and nipping roller 886 are provided at the outlet from the third set of the rollers 808 and 804 for obtaining a rubbing movement in the combined slivers. A breaking element 802 is provided at the inlet to the first set of the rollers 804 and 844 to break the first sliver S1 after the completion of the piecing operation.

摘要： An open end spinning machine and an associated traveling sliver can replacement carriage are provided with cooperating components for automatically replacing empty sliver cans at the spinning positions of the machine with full sliver cans and threading up the sliver for spinning resumption. An openable and closable sliver guide is provided at each spinning position in association with a sliver monitor which recognizes the presence and absence of sliver in the guide. A signal transmitter at each spinning position produces a can replacement signal when the monitor recognizes the absence of sliver in the guide. A program controller is associated with a signal receiver on the carriage to actuate exchange of the empty sliver can at the signaling spinning position with a full sliver can from the carriage. The program controller also actuates opening of the sliver guide, insertion of the sliver from the replacement can thereinto, and splicing of the leading end of sliver from the replacement can with the trailing end of sliver from the can previously in service.

摘要： A process is provided for connecting the end of a new fiber band to the end of a fiber band running into an open-end spinning arrangement wherein the threading on is conducted in such a manner that the joining point between the new fiber band and the fiber band already running into the spinning arrangement does not result into a change in the yarn number. In one embodiment it is provided that the fiber bands are prepared in such a manner and connected to each other, especially by means of twisting them together, such that a joining point exhibits at least approximately the same number as the other areas of the fiber band. In a second embodiment, it is provided that following a joining of the two fiber bands the feeding device of the spinning arrangement is switched on until the joining point is running into the spinning arrangement whereby the fibers fed during this time period are transported off within the spinning arrangement.

摘要： Two rows of cans, the number of which corresponds to half of the number of spinning units in a spinning frame, are arranged along each side of the spinning frame, with the inside cans half full of slivers and the outside cans full of slivers before starting the operation. Slightly before the slivers in the inside cans are used up, their ends are pieced with the slivers in full cans previously supplied in their standing-by positions backwardly of the outside row of cans. The empty cans in the inside row are moved inwardly onto a conveyer between the inside can rows and then the cans in the outside row, which are now half full of the slivers, are moved in the inside row and the cans in the standing-by positions are also moved in the outside row. The empty cans on the conveyer can be removed out of the spinning machine by driving the conveyer.
