  • the ends of the cross wire moved outwards and thus the Cross wire tensioned.
  • the tension force acting on the cross wire depends on the mechanical properties of the cross wire from and is set via the working pressure in the clamping cylinders 21, whereby this may only be chosen so large that the Cross wire stretched sufficiently taut without plastic deformation becomes.
  • the working cylinder 15 of the left and clamping device 4 and the working cylinder 15 'of right turning and tensioning device 5 activated accordingly, so that the twisting plate 10 of the left twisting and tensioning device 4 and the twisting plate 10 'of the right twisting and Clamping device 5 perform opposite rotary movements, whereby the left cross wire end corresponds to a direction of the Double arrow P5 is rotated about its longitudinal axis while the opposite right transverse wire end in a direction of rotation P5 opposite rotation according to the double arrow P6 is twisted.
