Embodiment Construction

[0028] An apparatus according to the invention for melt spinning, drawing, processing and winding a plurality of synthetic filaments is schematically shown in FIG. 1 . For the production of threads, the device has a spinning device 1 , a cooling device 2 arranged downstream of the spinning device 1 and a winding device 3 for winding up the threads.

[0029] The spinning device 1 has a plurality of spinning nozzles 8.1 to 8.6 arranged parallel to one another. The spinning nozzles 8.1 to 8.6 are held on the underside of the heatable spinning beam 7. The spin beam 7 contains a plurality of spinning pumps (not shown here) and melt distributors, which are connected via a melt inlet 12 to a melt source, for example an extruder. The spinning nozzles 8.1 to 8.6 have on their bottom an annular structure formed by a plurality of nozzle openings, through which a plurality of filaments can be extruded.

[0030] Below the spinning device 1 is arranged a cooling device 2 which is formed b...

Abstract

The invention relates to a device and a method for melt-spinning, drawing off, processing, and winding up several synthetic threads. For this purpose, several filament bundles are extruded from several spinning nozzles that are located next to each other, are cooled, and are combined into one thread, respectively. The threads are wound to bobbins in parallel next to each other after being drawn off and processed. In order to allow the threads to be combined into a thread bundle at the smallest possible deflection angles from a plurality of spinning nozzles, several drawing-off elements are provided which are assigned to a group of spinning nozzles and thus draw off a group of threads. Said drawing-off elements cooperate with at least one processing element that is mounted downstream thereof in such a way that the threads can be directed through the processing element as a thread bundle (36) with a parallel movement. The processing element is arranged beside the drawing-off element side or above the side. A collecting thread guide is arranged in front of each drawing-off element, and the threads configured for the drawing-off elements can be guided from a distributing space of the spinning nozzles to a guiding space through the collecting thread guide.

Description

technical field [0001] The present invention relates to an apparatus for melt spinning, drawing, treating and winding a plurality of synthetic threads and a method for melt spinning, drawing, treating and winding a plurality of synthetic threads. Background technique [0002] A similar device and a similar method are known, for example, from DE 44 16 136 A1. [0003] In the known device and the known method, a plurality of spinning nozzles are held in a row arrangement in a spinning device. A plurality of filaments are extruded through each spinning nozzle as a bundle of filaments and cooled with a coolant by a cooling device arranged below the spinning nozzles. Combination of the filament bundles produced by each spinning nozzle by means of an oiling device takes place after the filaments have cooled. In this case, the bond between the individual filaments to form a thread is achieved by means of an oiling agent. The individual threads are drawn together as a thread bund...
