Problems solved by technology

However, this alternate meshing on the toothed belt causes vibrations on the toothed belt, known as the polygon effect, which can adversely affect the uniformity of the traverse at the winding station
Polygonal effects are additionally facilitated by unequal manufacturing tolerances on the profile sides

Embodiment Construction

[0024] figure 1 with figure 2 An exemplary embodiment of a winder according to the invention is shown from different perspectives. figure 1 A front view of the exemplary embodiment is schematically shown, figure 2 A top view of the exemplary embodiment is schematically shown. The following description applies to both figures as long as reference is not made to either figure.

[0025] The illustrated exemplary embodiment of the winder according to the invention is typically used in the production of synthetic yarns in a melt spinning plant to wind a set of yarns which are extruded, drawn and Processed into yarn groups and delivered to the winder. In the winder, one of several winding stations is formed for each yarn.

[0026] as available from figure 2 As can be seen from the illustration, the exemplary embodiment has a total of four winding stations 5.1, 5.2, 5.3 and 5.4 for winding the yarn into bobbins 6.1 to 6.4, respectively. For this purpose, the bobbins 6.1 to ...

Abstract

A bobbin winding machine with a plurality of winding stations which are arranged along a bobbin winding spindle for winding a plurality of threads into bobbins is described. The winding stations are assigned a traversing device which has a flyer traversing unit for each winding station. The flyer traversing units are driven jointly and for this purpose have in each case a drive wheel which is coupled to a driven driving wheel via a toothed belt. The toothed belt is coupled to the toothed drive wheels and to the toothed driving wheel via a toothed profile side.

Description

technical field [0001] The invention relates to a winding machine with a plurality of winding stations. Background technique [0002] A universal winder is known from EP0965554A2. [0003] This type of winder is used in the production of synthetic yarns for the purpose of winding the yarn into bobbins. In this case, depending on the yarn process and type, very high yarn travel speeds will result, which may exceed 6000 m / min. Since during melt spinning the yarn is extruded, processed and guided into yarn groups at the spinning position, it is possible to wind the yarn and the bobbin in parallel next to each other. For this purpose, bobbin winders are known which have a protruding bobbin winding shaft on which a plurality of distributedly arranged winding stations are formed. In order to be able to wind the yarn onto the bobbin in a cross-winding manner, a traversing device is provided which has a flyer traversing device for each winding station. Flyer traversing devices o...
