Embodiment Construction

[0027] exist figure 1 and figure 2 A first exemplary embodiment of the device according to the invention for carrying out the method according to the invention is shown schematically in several views. figure 1 The embodiment is shown in front view, figure 2 Shown in side view. The following description applies to both figures unless otherwise specified for the figures.

[0028] according to figure 1 and 2 The exemplary embodiment of the invention has a spinning device 1 with a total of three spinning nozzles 4.1, 4.2 and 4.3 arranged side by side. The number of spinning nozzles in the spinning device 1 is exemplary, but also much more than three filaments per spinning position. The spinning nozzles 4.1 , 4.2 and 4.3 are held on the bottom of the heated spin beam 3 . The spin beam 3 also includes melt-conducting elements, not shown here, in order to feed the melt-sourced thermoplastic melt supplied via the inlet 2 to the spinning nozzles 4.1 to 4.3. At least one or mo...

Abstract

The invention relates to a process for melt-spinning, drawing and winding multiple synthetic threads and also 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 realise for each thread the same conditions during extrusion, cooling and hauling off. To perform the process of the invention, the apparatus includes multiple individual godets arranged side by side which are arranged upstream of the drawing facility and are each assigned to one of the threads. To haul 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...
