Embodiment Construction

[0037] figure 1 A schematic diagram of a first exemplary embodiment of a device according to the invention for carrying out the method according to the invention is shown. In this example, only two spinning stations are shown for the sake of clarity to produce two groups of filaments, each containing five filaments. Usually, several such spinning stations are arranged side by side to produce many synthetic threads. Accordingly, the number of filaments per spinning station is also exemplary. Typically, at least 8 up to a maximum of 32 filaments are extruded and cooled in parallel in one spinning station.

[0038] exist figure 1 In the illustrated embodiment, the spinning stations 1.1 and 1.2 are arranged side by side. The spinning stations 1.1 and 1.2 are constructed identically. Accordingly, each spinning station 1.1 and 1.2 has a spinning beam 2 and a cooling device 6 arranged below the spinning beam 2 . On its upper side, the spin beam 2 has a spinning pump 3 which is ...

Abstract

The invention relates to a method and device for melt spinning and cooling a plurality of synthetic threads extruded and cooled in groups in a plurality of adjacently operated spinning stations. A cooling air flow for cooling the respective threads is fed to the spinning stations, said flow being fed by a common cooling air flow source. In order to be able to introduce a change to the cooling air flow, in particular in the case of operational faults, according to the invention, a flow rate of at least one of the cooling air flows of the respective spinning stations is changed independently of the cooling air flow source. To this end, a supply line associated with the spinning station comprises an adjuster for setting the flow rate of the cooling air flow.

Description

technical field [0001] The invention relates to a method for melt spinning and cooling a plurality of synthetic threads and to a device for carrying out the method. Background technique [0002] A similar method and a similar device are known, for example, from WO 2005 / 052224 A1. [0003] In the manufacture of synthetic threads, it is usually necessary to manufacture a large number of synthetic threads. For handling, especially during process start and process interruption, the threads are extruded and cooled in groups by a plurality of spinning stations arranged side by side in the spinning plant. The threads produced by the spinning station are collectively wound into bobbins by a winding device assigned to the spinning station. Depending on the characteristics of the winding unit, 8 to 32 yarns can be produced simultaneously in one spinning station. The spinning stations run side by side and are built together in one hall. In order to be able to cool the freshly extru...
