Definitions

  • the upper roller is carried by a frame which can pivot around a horizontal axis under the action of a jack pneumatic, between a raised position allowing free passage of the band and a lowered position for pinching the band, the level is adjusted by fixed stops.
  • Fig. 3 is a detail view, on an enlarged scale, of FIG. 2.
  • the chassis 6 is applied by the jack 7 to adjustable stops 8 of the frame 3, the level of which can be adapted to the thickness of the strip S so that it is pinched between the two rollers 4, 5.
  • the clamping force is exerted only by the cylinders 10 which are preferably single acting, the weight of the roller 5 being collected by balancing jacks 20 which are supported on the lifting frame 6.
  • the cylinders 20 for balancing the weight of the roller 5 are supplied permanently with a slight overpressure so as to apply the bearings 54 on the ends of the pushers 13 of the jacks 10 while exerting thus an effort of recall upwards.
  • the servo valves 30 supply of the cylinders 10 make it possible to precisely control the pinch pressures applied respectively to the sides of the strip, by means of a regulation system shown schematically in Figure 4.
  • the output signal from camera 21 is sent to the input of a gap shaping circuit 22. Leaving the circuit 22 is connected to an input of a comparator 23 including another input receives, via line 24, a setpoint for the cylinder 5 tilt control. Comparator 23 output is sent to an input of a microcomputer 25. Other inputs of this microcomputer 25 are respectively connected to a line 26 providing a pressure limit value, a line 27 providing a setpoint of the position of the rod 13, a line 28 receiving the sensor 15 information on the position measurement and a line 29 receiving information from the pressure sensor 16.
  • the second part of the damping chamber B includes a volume filled with gas, advantageously constituted by an accumulator gas 17 whose outer shape is substantially cylindrical and centered, preferably, on an axis orthogonal to that of the jack 10.
  • the accumulator 17 is fixed laterally on the cover 12a which comprises a transverse passage duct 18 which opens into the capacity 14 to put it in communication with the accumulator 17.
  • the diameter of the passage duct 18 is large enough to avoid a dynamic variation of the pressure during the passage of the liquid in capacity 14.
  • the separation between the liquid in capacity 14 and the gas from the accumulator 17 is provided by a shutter without inertia, by example formed by a partition 19 applied to the bottom of a counterbore formed around the periphery of conduit 18.
  • the inflation pressure of the accumulator 17 is adjusted to a value slightly higher than a set pressure pressure limit in capacity 14 to exert the necessary effort on strip 2 during from its introduction and during its scrolling. This overpressure, which may vary depending on the product, is therefore collected, in operation normal, by the partition 19 for closing the duct 18.
  • the bottom 112a of the clamping cylinder 110 is widened so as to constitute a piston mounted sliding in the body 32 of the jack tire 31, the rod of which is formed by the body 112 of the actuator tightening 110.
