Embodiment Construction

[0036] figure 1 is a side view of the station 2 of the winding machine 1, in the embodiment shown a so-called automatic cross-winding device during the winding process. Such an automatic cross-winding device 1 has, between its (not shown) end positions, a plurality of stations 2 of the same type, so-called winding stations.

[0037] On the winding station 2, as known, therefore without further elucidation, the feed bobbin (usually the spinning bobbin 9 produced on the ring spinning machine, which has only relatively little yarn material) is wound into Large-volume cross-wound bobbin 11. The finished cross-wound bobbins 11 are then handed over to the cross-wound bobbin transport device 21 along the machine length by means of an automatically operating service device, such as a cross-wound bobbin changer, and transported to the Package loading station or similar.

[0038]Furthermore, such an automatic cross-winding device is either equipped with an endless magazine in which t...

Abstract

The invention relates to a method and a device for cutting a running yarn (30), wherein a clock-pulsed laser beam (41) is spatially focused by means of optical elements (37, 43), and the running yarn (30) is The region (42, 48) where the laser beam (41) is focused is guided through. According to the invention, the laser beam source (36) and the optical elements (37, 43) are arranged and designed such that the laser beam (41) emitted by the laser beam source (36) is bundled by the optical elements (37, 43). The mechanism for guiding the advancing yarn (30) is configured to cause the advancing yarn to be guided through the region (42, 48) where the laser beam (41) converges, the control device (51) being configured for The laser beam source (36) is activated to cut the yarn (30).

Description

technical field [0001] The invention relates to a method for cutting a running yarn and a device with means for guiding and cutting the running yarn. Background technique [0002] Different arrangements are known for cutting the running yarn. In simple constructions, the yarn is guided between the scissors and the anvil. Here, the blades of the scissors extend transversely to the direction of yarn travel. To cut the yarn, the scissors are moved electromagnetically or pneumatically relative to the anvil. The movement of the scissors relative to the anvil causes heavy wear on the blades, which means that the scissors become dull over time. [0003] Patent document DE 100 50 692 A1 discloses an alternative to a cutting device for the running yarn. Here, the yarn is simultaneously pressed against the cutting plate by means of the clamping mechanism, and the scissors slide along the end faces of the cutting plate and cut the advancing yarn. [0004] A known solution for cutt...
