  • the yarn 15 taken from the spool 15 first passes through a yarn guide 16 and is thereafter trained about two godets 17 and 18. From the second godet 18 the yarn enters a drawing zone 19 in which it is stretched by heat treatment eiiected by means of a hot plate 20.
  • the yarn is taken from the drawing zone 19 by a godet 21 with a constant speed, then guided through a yarn tension meter 22.

  • the spindles 33, 33' are shown in their lowest position in which no yarn is wound thereon. During operation, however, there is at all times at least one spindle in such a position that the spool inserted thereon extends into the inner space of the bell and thus is in a position to receive the advancing yarn.
  • a spool After a spool is fully wound, as in the case of the left hand spool 34, it is moved downwardly into its shown lowest position by lowering its associated spindle. In this lowest position then an empty spool is substituted for the completed yarn package. Similarly, as soon as the other spool is fully wound, an empty spool will be substituted therefor.
  • the yarn by means of the deflector head 24, is redirected from the then operational yarn outlet channel into the other yarn outlet channel which leads to the winding station then having an empty spool. In this manner, the yarn may be wound alternately on the two spindles of the winding stations 12 and ⁇ 13 without interruption undergoing at the same time a twisting treatment. Such twisting is, as usual, only slight in a stretchtwisting machine as shown.

  • the tension of the yarn to be wound is set preferably to a constant value.
  • the control of the yarn tension is effected by varying the rpm. of the individual spindle drive motors 31, 31' by means of a regulator 44 (FIG. 3).
  • the spindle carrying the empty spool is driven with an r.p.m. which is necessary to obtain approximately the required yarn tension as the yarn is wound on the empty spool.
  • the yarn tension regulating device is switched, so that it affects henceforth the spindle r.p.m.
  • FIG. 3 illustrates a block diagram of a circuit for effecting a yarn tension control.
