    摘要: A process of automatic yarn spinning-in in the spinning unit of an open-end rotor spinning machine of an automatic service device provided with a control unit having a programmable microprocessor control system for controlling the spinning-in cycle and the automatic adjustment of spinning-in parameters modified according to successive verifying tests which are performed by the automatic service device which is either arranged in the individual spinning units, or as a unit traveling along the machine. By successive tests, spinning-in parameters are adjusted for an interval for yarn return to the spinning rotor as well as for determining the start of fiber feeding. The spinning-in parameters can be corrected by further verifying tests in spinning units with various dynamic characteristics.

    摘要: A device is provided which solves the problem of feeding cop tubes in a textile machine from a supply container to a withdrawing station by means of a conveyor disposed in a conveying channel extending along the machine above the spinning units. The conveying channel has a side wall and a lower horizontal support wall on the upper slide surface of which there is disposed an endless belt of the conveyor. Above the belt there is provided, on the one hand, at the beginning of the conveying channel, an outlet for the supply container for cop tubes to be deposited onto the endless belt, and, on the other hand, in a cop withdrawing station, a retaining unit for arresting the movement of the tube being supplied. The retaining unit comprises a catch which has a blocking arm with an abutting front end provided at the tube supply side and oriented across the endless belt of the conveyor, and a lifting arm with a contacting surface for engaging a tube traveling along the belt.

    摘要: The invention relates to an apparatus for the spinning-in of yarns in an open-end rotor spinning unit. The apparatus includes a spinning-in device for returning yarn end through a take-off duct into the spinning rotor, a severing device for shortening the yarn end to a predetermined length, and a withdrawing duct which communicates with the take-off duct and which is designed, on the one hand, for holding the yarn end by the action of a vacuum which, in the contact region of the two ducts, exceeds the working vacuum in the take-off duct, and, on the other hand, for withdrawing the severed yarn end. In accordance with an essential feature of the invention, at least one air nozzle opens into the withdrawing duct which during both spinning and spinning-in processes is connected to a subatmospheric pressure source, which nozzle is designed for introducing a fresh yarn end into the take-off duct by a controlled air outflow in a particular phase of the spinning-in process. The invention expediently utilizes the subatmospheric pressure air for both the spinning-in process and the withdrawal of impurities from the yarn in the take-off duct of the spinning rotor during the spinning process.

    摘要: An improved technique for stopping the advance of spun yarn through the draw-off rollers and distributing cylinder of an open-end spinning machine in response to a detected yarn breakage condition is described. A reversible clutch is selectively interposed between first and second oppositely rotating drive shafts and the cylinder, which in turn is coupled to the draw-off rollers. The clutch is operated from a normal forward advance condition to an operated reverse condition for a duration corresponding to a variable-duration control pulse generated in response to a yarn breakage condition upstream of the discharge end of the machine withdrawal tube. The duration of the control pulse is adjusted to dynamically brake the forward motion of the advancing yarn to a stop. The control pulse is removed soon enough to prevent reverse movement of the yarn.

    摘要: A method of and an apparatus for piecing yarn in open end rotor spinning units. The returning of the yarn end into the spinning rotor for piecing is performed in two stages, in the first of which the yarn is stopped immediately upon breakage within the sucking range of the spinning rotor, and is brought immediately thereafter into a withdrawal chamber in which the yarn end is retained. In the second stage the yarn end is separated and deposited in said withdrawal chamber, and the new yarn end is introduced by further reverse motion into the spinning rotor. The apparatus has a withdrawal chamber interposed between the inlet of the withdrawing channel and a cutting mechanism. In one embodiment said chamber is connected to the withdrawing channel, opposite which there is mounted a nozzle connected to a controlled pressure air source. In another embodiment there is provided a nozzle communicating with the withdrawal chamber, said nozzle being connected to a controlled source of underpressure.

    摘要: An open-end spinning machine, is operated by continuously advancing a yarn towards a take-up station at which it is wound onto a bobbin rotating at a predetermined speed, so that a yarn package forms on the bobbin and the latter eventually becomes full. As the bobbin approaches a condition of fullness, an empty bobbin is rotated adjacent to it and is accelerated until it reaches the speed at which the full bobbin rotates. The yarn which advances onto the full bobbin is then severed from the yarn package on the latter, to provide a free yarn end which is inserted into one axial end of the rotating empty bobbin, to be engaged and entrained by the latter whereby winding of the free yarn end onto the empty bobbin commences. The full bobbin is now removed from the station and is replaced with the rotating empty bobbin.
