Problems solved by technology

Yarn clusters make it difficult to receive the yarn wound onto the bobbin by the suction nozzle and thus perform the yarn connection
If the already wound yarn cannot be picked up by the suction nozzle, manual intervention by the operator is required
[0007] In addition, yarn coils that have not been "pre-cleaned" can undesirably catch or hold on to vulnerable parts in the winding position along the yarn path, thus causing damage to these parts

Embodiment Construction

[0023] figure 1 The station 2 of the winding machine 1 (in the present exemplary embodiment a so-called automatic cross-winding winding machine) during the winding process is shown schematically in side view. Such an automatic cross-winding winder 1 has a plurality of identical stations 2, so-called winding positions, between its end frames (not shown).

[0024] On these winding positions 2, as is well known and thus not described in detail, the feed bobbins (which are generally produced on ring spinning machines and have only relatively little yarn material bobbins 9) are rewound. A cross-wound bobbin 11 that is rewound into a large package. The wound cross-wound bobbins 11 are then handed over to the cross-wound bobbin conveyor 21 along the machine length by means of an automatically operating maintenance device (for example a cross-wound bobbin changer) and conveyed to the Package loading station, etc.

[0025] Furthermore, such an automatic cross-winder is either equipp...

Abstract

The invention relates to a station (2) of a winding machine (1) for winding a yarn (30) from an unwinding bobbin (9) to a winding bobbin (11), wherein the Yarn loop catchers (23, 23A, 23B) are arranged adjacent to the yarn path between the unwinding bobbin (9) and the winding bobbin (11), and the yarn loops The catching device (23, 23A, 23B) has a plurality of catching elements (43, 44, 51) spaced apart from the yarn path, said catching elements facing the progress of the yarn (30) Direction (F).

Description

technical field [0001] The invention relates to a station of a winding machine for winding yarn from a take-off bobbin to a winding bobbin, wherein the yarn path between the unwinding bobbin and the winding bobbin is adjacent Set the yarn loop catch device properly. Background technique [0002] DE3843553A1, which constitutes the above-mentioned type, discloses a winding station which winds the yarn from the cop to the cross-wound bobbin. The winding position has a yarn coil unwinding mechanism. Its task is, before the yarn coils and crimps reach the yarn tensioning mechanism, where they can cause yarn breaks, or before they reach the yarn clearer, where they always cause the yarn clearer to cut and thus the winding to be interrupted Beforehand, loosen loops and curls that occur especially at low yarn tensions. [0003] The yarn coil unwinding mechanism has two arms that can be brought into contact with each other and separated, and the arms are formed as scissor-like ove...
