Embodiment Construction

[0025] exist figure 1 A first embodiment of the apparatus according to the invention for carrying out the method according to the invention is shown in and 2 . in figure 1 A front view of this embodiment is shown, and FIG. 2 shows a schematic rear view thereof.

[0026] first by means of figure 1 The structure of this embodiment will be described.

[0027] This exemplary embodiment of the device according to the invention has two winding locations 29.1 and 29.2 which are arranged side by side in a machine frame 12. In this case, the winding locations 29.1 and 29.2 are formed mirror-symmetrically with respect to a central symmetry plane. For example, the winding position 29.1 consists of a spindle frame 10.1 rotatably supported on the frame 12, a cantilevered first bobbin spindle 7.1 is supported on the spindle frame 10.1, and a cantilevered first bobbin spindle 7.1 is supported at an offset of 180°. Two bobbin spindles 11.1. Here the first bobbin spindle 7.1 is in the wo...

Abstract

The invention relates to a method for winding several threads to form bobbins. The bobbins (9.1; 9.2) are held on two adjacent parallel bobbin spindles (7.1; 7.2) and are driven in opposite directions during the winding of the threads with predetermined surface speeds. During said process two respective pressure rolls (6.1; 6.2), which are rotatably mounted and lie against the periphery of the bobbins (9.1; 9.2), co-operate with the bobbin spindles (7.1; 7.2). To maintain both bobbins (9.1; 9.2) at a speed that is as similar as possible during the winding of the threads on both bobbin spindles (7.1; 7.2), the rotational speed of one of the pressure rolls is detected (6.1; 6.2) in order to control the surface speed of the bobbins (9.1; 9.2) and to collectively modify the drive speed of both bobbin spindles (9.1; 9.2) in accordance with the detected rotational speed, in such a way that the detected rotational speed of the pressure roll (6.1;6.2) remains essentially constant.

Description

technical field [0001] The invention relates to a method for winding a plurality of filaments into a package, and to a device for carrying out the method. Background technique [0002] In the production of synthetic filaments, the tendency is increasingly observed that a large number of filaments are simultaneously spun parallel side by side from a polymer melt in one spinning station and then wound up into a package. It is known, for example, to spin ten, twelve, sixteen or more filaments in parallel and simultaneously wind them into a bobbin. The winding of the filament here can take place by means of a winder, in which the bobbin is supported and wound on the bobbin spindle. Such winders require relatively long bobbin spindles for large package widths and high numbers of filaments. A new concept was therefore developed in which the yarn is wound simultaneously into a package on two bobbin spindles arranged parallel to one another. Such a method and device are known fro...
