Embodiment Construction

[0029] A first exemplary embodiment of the device according to the invention is shown in several views in FIGS. 1 and 2 . Wherein Figure 1 schematically shows a side view of the device, figure 2 Schematic representation of a cross-sectional view. If it is not specified which figure is referred to, the following description applies to both figures.

[0030] The device has a base 1, which consists of a plurality of branch bases 1.1, 1.2, 1.3 and 1.4 combined with each other. Each branch seat 1.1 to 1.4 supports a plurality of devices involved in winding the yarn into a bobbin. For example, a bobbin carousel 2 is mounted rotatably in the branch seat 1.1. Two cantilevered long bobbin spindles 3.1 and 3.2 are arranged on the bobbin carousel 2 offset from one another. On the free ends of the bobbin spindles 3.1 and 3.2, a plurality of bobbins 4 are sequentially put on and clamped respectively. On the bobbin spindle 3 . 1 held in a working area by the bobbin carousel 2 , the fil...

Abstract

The invention introduces a method and a device for winding multi-ply filament on a rotating bobbin spindle to be a drum. The filament is respectively and reciprocally guided before the filament is paved on the drum and partially moves on the circumference of a rotatable back-up roller in a winding way. In order to keep winding speed which is basically constant, the operation speed of the bobbin spindle is continuously changed. Thereby excitation which is formed produces influence on the component which is fixed through a branch support stand of a frame, wherein each component is respectively provided with a certain fixed frequency. In order to avoid critical vibration status in the component, the fixed frequency is changed according to the operation rotary speed of the bobbin spindle through a rigidity reinforcing device of a branch supporting stand which can be converted on at least a component according to the invention. Therefore the branch supporting stand is provided with a mechanism for controlling the rigidity of the branch supporting stand, thereby changing the fixed frequency of the relative component during the winding period of the filament.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for winding a multifilament yarn into a bobbin, and a method according to the preamble of claim 10 for winding a multifilament filament into a bobbin barrel device. Background technique [0002] A method of this type and a device of this type are known, for example, from DE 42 40 920 A1 for winding a plurality of filaments into a package. [0003] This device is used in the manufacture of synthetic filaments to wind them individually into bobbins after spinning. In order to achieve high filament draw-off speeds in such spinning processes, the bobbin spindles used to support the reel must pass through a very large rotational speed range up to 30,000 rpm depending on the diameter of the reel, so that especially with the reel installed The dynamics of the bobbin spindle of the drum forcefully cause the excitation. This vibration is transmitted through the machine base or through com...
