Definitions
- the invention relates to a device for the production of synthetic threads, in particular polyamide threads, according to the preamble of claim 1.
- the godet device for removing the threads from a spinning device is formed by a plurality of groups of godets.
- a first group of a plurality of driven godets serves to strip the threads from the spinning device.
- the relaxation of the threads is carried out on a second godet group with several driven godets.
- a subsequent aftertreatment of the threads is carried out by means of a third group of several driven godets, wherein the godet groups are arranged in succession to form a threadline. in this connection the threads are each guided on the circumference of the galette gillets with simple wrapping around each other.
- the contact lengths of the thread on the circumference of the godet coats of the godets are each limited to a partial looping, so that in particular the minimum contact lengths required for heating the thread can only be achieved by increasing the number of godets.
