  • Barre 19.3 In Barre 19.3 several reversing rail support 19.4 are stored.
  • Each carries a turning rail pair 4, 4.1, which belongs to a folding drafting double. By this design, the straps 3 can be easily mounted.
  • the adjustment in height is done for example via a screw 19.6 which runs against a compression spring 19.8.
  • the adjustment in the angle takes place by pivoting about the axis 19.7, which is rigidly connected to the bar 19.3.
  • the pivoting is initiated outside the side walls 1.1 by a calibratable mechanism 19.9. With this preferred embodiment, all turning rails 4, 4.1 can be brought precisely into a desired position.
