Abstract
A parallel spinning process, in particular for filaments, e.g. for textile or industrial applications, made from polymers such as, for example, PET or PA, in each case having a thread interlacing device between two godets for each individual thread, the godets being moved in relation to one another during the piercing or feeding operation in such a way that each individual thread is automatically threaded into its interlacing device associated therewith, and the angle of wrap in the operating mode is at least from 85° to at most 200°, preferably from 175° to 185°.
