  • the blank 14a is on a piston rod 16 of the horizontal piston-cylinder unit 11 attached by means of a screw 17.
  • the piston 18 of the horizontal As can be seen, the piston-cylinder unit 11 is double-sided with pressure medium acted upon.
  • the pressure medium for the piston-cylinder unit 11 is fed through channels 19 and 20 to the two piston sides. Channels 19 and 20 run within the stand frame 9.
  • the channels 19 and 20 open in grooves 22 running around the cylinder 21 or around the piston rod 16 23.
  • the circular outer shape of the round blank 14a is visible in FIG.
  • the control of the hydraulic pressure in the piston-cylinder unit 11 to the different pressures Adjustment of play when actuating the vertical roller adjustment drive or Eliminate play for chock 6 or 7 by operating the horizontal Piston-cylinder unit 11 in the guide 8 and the respective stator side 9a or 9b adjusted and controllable accordingly, for what with a vertical adjustment the chocks 6 or 7 with the support rollers 2 or 3 the control is switched to signals of an automatic gage control system.
  • FIG. 5 Another embodiment (Fig. 5) provides a connection to one at a Roll pin 4a or 5a, perpendicular to the roll axis 24 Bending cylinder 25 before.
  • the blank 14a is the support member 14 in the piston-cylinder unit 11 from several smaller piston-cylinder units 27 consisting of a distance 26 (see FIG. 6) to Bending cylinders 25 run, formed.
  • the piston head 11b is with the round blank 14a Mistake.
  • the relatively large piston head 11b and the relatively small piston-cylinder units 27 can expediently by means of Allen screws 33 be connected so that the respective piston head can also be withdrawn.
  • Polygonal corners 28 are symmetrical to the axis 25a of the bending cylinder 25 the smaller piston-cylinder units 27 are arranged for the round blank 14a (FIG. 7).
