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.
