  • a spinning system with such a spinning beam is known, for example, from DE-PS 24 38 364 (Bag. 905) and DE-OS 41 03 990 (Bag. 1811) or the unpublished DE 195 13 941 A1.
  • the arrangement of the spinneret plates in a row results in a large longitudinal extension of the spinning system.
  • a spinning beam according to the preamble of claim 1 and a spinning system with such a spinning beam according to claim 2 are known from EP 0 285 736 B1. This makes it possible to spin an even larger number of threads in a system that is as compact as possible, and in particular to avoid non-uniform heat losses which can lead to non-uniformity of the threads.
  • the solution for the spinning beam results from claim 1.
  • the solution for a spinning system according to claim 2 results from the characteristic of Claim 2.
  • the spinning beam according to claim 1 has the advantage that all spinnerets housed in a single heating box are, the length of the heating box is limited such that there are no temperature differences along its length can and that each row of spinnerets each have a multiple spinning pump assigned. This results in particular also the advantage of greater flexibility, as in the event of a malfunction on one of the pumps not the entire spinning system except Must be put into operation.
  • the spinning system according to claim 2 has the advantage that you blow box can be interpreted so narrow that it is between two There is space for a row of nozzles in a close arrangement.
  • the Blow boxes are independent of each other and by two separate ones Blowers are supplied with blown air (claim 3).
