Embodiment Construction

[0019] figure 1 and figure 2 Respectively shown are a side view and a front view of the workstation 2 of the semi-automatic open-end spinning machine 1 . Spinning machines of this type are known to have a plurality of workstations 2 of the same type arranged one after the other in a row, each having a spinning device 3 and a winding mechanism 33 as important functional elements.

[0020] In the spinning device 3 , the fiber sliver 34 fed into the spinning can 28 is spun into a yarn 30 , which is then wound into a cross-wound package 22 on a winding device 33 . As known per se, the winding mechanism 33 has for this purpose respectively: the creel 21 for rotatably holding the bobbin of the cross-wound bobbin 22, the bobbin drive roller 23, the yarn traversing mechanism 26, and the The mechanism 7 for cross-winding the bobbin 22 is lifted from the bobbin drive roller 23 . The mechanism 7 is configured, for example, as a thrust piston drive, which is connected via a pneumatic ...

Abstract

The present invention relates to a method of operating a spinning station of a semiautomatic open end spinning frame and spinning station to implement the method. The spinning station includes a spinning device for producing a thread, a thread stripping mechanism driven by a single motor, and a winding device for forming a cross-wound bobbin. A length of a faulty thread, which overriding on the cross-wound bobbin, is determined during occurrence of thread fault. A spinning process at a functional area (2) is interrupted. The cross-wound bobbin is rotated unwinding of the faulty thread manually against a winding direction (R). The unwinding length of the faulty thread is monitored. A signal is indicated, when the faulty thread is unwounded again by the cross-wound bobbin.

Description

technical field [0001] The invention relates to a method for operating a workstation of a semi-automatic open-end spinning machine and the workstation. Background technique [0002] A known semi-automatic open-end spinning machine is described in detail, for example, in DE 10 2005 036 485 A1. This textile machine also differs from the fully automatic open-end spinning machines widely used in the textile industry in that this semi-automatic free-end spinning machine does not have movable service components that automatically supply the workstations of these textile machines when required. This means that in semi-automatic open-end spinning machines, the kind of service work that is carried out in fully automatic open-end spinning machines by service components that can be moved along the workstation, is performed manually by the operator. For example, after a yarn break or a controlled spinning interruption due to a yarn defect, the operator has to find, for example, the end...
