Abstract

The invention relates to a process for melt-spinning, drawing and winding multiple synthetic threads and to an apparatus for performing the process. The synthetic threads are spun concurrently side by side through extrusion of fine filamentous strands, cooled down and hauled off to be then collectively drawn as a sheet of threads and wound up on bobbins. To obtain ideally identical physical properties in the collective treatment of the threads, the threads are hauled off independently of each other by separate individual godets after extrusion and before collective drawing. This makes it possible to realize for each thread the same conditions during extrusion, cooling and hauling off. The apparatus includes multiple individual godets arranged side by side, which are arranged upstream of the drawing facility and are each associated with one of the threads. To pull off the threads, the individual godets are configured to be individually driveable.

Description

technical field

[0001] The invention relates to a method for melt spinning, drawing and winding a plurality of synthetic filaments according to the preamble of claim 1 and to a method for carrying out this process according to the preamble of claim 7 method equipment. Background technique

[0002] When producing synthetic filaments in a melt spinning process, usually multiple filaments are extruded side by side in parallel at the spinning position, cooled, drawn and wound into spools. After extrusion, the filaments are guided as filament tufts and drawn collectively over godet rollers and wound up collectively to form a bobbin by means of a winding device with a plurality of winding locations. In order to be able to simultaneously withdraw a plurality of filaments from the spinning nozzle via the godet, the filaments are generally also converging in the first transition section with relatively small filament spacings relative to each other. During extrusion and cooling, th...
