Definitions

  • FIG. 6 shows a close-up view of the detail indicated by VI in FIG. 5 ;
  • Each stand 22 comprises, in a manner known per se, a plurality of actuators 21 , a plurality of motor-reducer-spindle units 23 , and a roll-holder cartridge 24 .
  • FIG. 3 the diameter of the roll 3 has been reduced by the successive turning reconditioning operations which were necessary during the first half of the working life of the roll 304 .
  • the reduction in the diameter of the roll 304 is compensated for by means of displacement of the pin 300 in the tangential direction parallel to the groove plane.
  • the reduction in the diameter of the roll 304 is schematically indicated in FIG. 3 by the arrow b, while the displacement of the pin 300 is schematically indicated by the arrow d.
  • the cartridge 24 comprises an adjusting actuator 32 suitable for imparting to the adjusting rings 28 a rotation about the axis X.
  • This adjusting actuator 32 may assume different forms, such as that of a mechanical screw jack, a mechanical worm screw and rack jack, a hydraulic jack, etc.
