Problems solved by technology

[0009] This yarn shifting device with finger guides has proven to be extremely flexible in practice, however, like the yarn guide cylinder, it has the disadvantage that there is always such a danger in controlled yarn clearer cutting , that is, the upper yarn connected to the cross-winding bobbin does not run normally onto the cross-winding bobbin, but falls as a so-called Fallfaden next to one of the end faces away from the cross-winding bobbin and is no longer Can be picked up by the yarn suction nozzle of the station

Embodiment Construction

[0031] figure 1 A station 2 of a textile machine 1 for producing cross-winding bobbins, which in the present example is a so-called automatic cross-winder, is shown schematically in side view.

[0032] As is known, such an automatic crosswinder 1 each has a plurality of identically constructed stations 2 between its (not shown) end frames. As is also known and therefore not described in detail, at these winding stations 2 the spinning cop bobbins 3 produced on the ring spinning machine are rewound into bulky cross-wound bobbins 5, cross-wound After the bobbin 5 has been completed, it is transferred to a cross-wound bobbin conveyor 7 arranged along the longitudinal length of the machine by means of a service unit (not shown) such as a cross-wound bobbin changer and conveyed to the side bobbin loading station or similar.

[0033] Furthermore, such an automatic crosswinder 1 usually also has a supply device in the form of a bobbin and sleeve transport system 6 .

Abstract

The method involves providing a bobbin frame (8) for rotatably holding a cross-wound bobbin (5), where the cross-wound bobbin includes two bobbin edges. A single-motor drive (14) of a thread laying device (10) is controlled in adjustment with a position of a free thread end of a thread (16) connected to the cross-wound bobbin in an event of interruption in winding, such that a finger thread guide (13) of the thread laying device displaces the free thread end in a direction of one of the bobbin edges and positions the free thread end with defined length outside of the bobbin edge. An independent claim is also included for a workstation comprising an angular sensor.

Description

technical field [0001] The invention relates to a method of operating a station of a textile machine for manufacturing cross-wound bobbins and a station for carrying out the method. Background technique [0002] As is known, in order to produce a cross-wound bobbin, not only must the relevant textile bobbin rotate about its bobbin axis, but the yarn running onto this textile bobbin must also traverse at a relatively high speed along the bobbin axis. The bobbins formed here must not only have a relatively stable structure but also have good unwinding properties. [0003] Since modern textile machines producing cross-wound bobbins, such as automatic cross-winders, operate at high winding speeds of up to 2000 m / min, the traversing speed of the yarn displacement system must also be correspondingly high. Various yarn displacement systems associated with such automatic cross-winders have been disclosed with which the required high traverse speeds can be achieved. [0004] For ex...
