  • the document EP-A-035.009 describes a machine for bending or straightening sheets with the features of the preamble of claim 1, comprising cylinders, respectively upper and lower, which each lean on a cross member via a series of rollers distributed over the length of the cylinder and whose levels can be adjusted individually by cylinders.
  • Each support roller or group of rollers is carried by a housing mounted at the end of the rod a jack whose body is fixed to the cross member and whose the piston is provided with a feeler coming into contact with a sensor fixed on a rule independent of the crosspiece and defining a straight reference level.
  • each sensor determines a correction of the piston position of the corresponding cylinder to correct the level of the rollers to maintain the straightness of the roller and therefore ensure uniform distribution of the pressure applied over the band width.
  • the defects observed may have other causes and, for example, come from heterogeneity transverse in the strip bearing, for example, on the profile, elastic limit or temperature, and who can cause differences in constraints and, by Consequently, differences in the elastic return of different longitudinal fibers when passing through the leveler.
  • the object of the invention is therefore to resolve this kind of problems and prevent the formation of such defects through to a much more effective correction device than known devices and which allows, in particular, to precisely distribute the compensation effect over the length of each leveling cylinder so as to correct, with great precision, all kinds of faults detected on the tape or predicted by calculation, at using a model for example.
  • the element mobile of each actuator is supported on the housing the corresponding support member by a thrust face determining a substantially punctual support in the axis of the actuator and kept in contact with the housing by the means for returning the housing in the opposite direction.

  • Each support member normally includes two or more three separate support rollers, rotatably mounted on the case around an axis parallel to that of the cylinder leveling, and preferably associated with two rollers intermediaries interposed between the leveling cylinder and said rollers.
  • each case a support member is connected with play and kept applied by the return means against a support frame which is kept applied, in service, on the bearing face of the cross member, said chassis being provided with a series of orifices, respectively to the right of each housing for the passage of the movable element of the actuator associated with said housing.
  • an intermediate piece can be interposed between the movable element of each actuator and the housing of the corresponding support member, said part intermediate being slidably mounted in the orifice support frame, perpendicular to the axis of the cylinder, so as to form a piston actuated by the positioning member.
  • each leveling cylinder is rotatably mounted on two bearings each carried by a support fixed to the chassis, this last thus carrying the entire leveling crew comprising the leveling cylinder, optionally one or several intermediate rollers and the supporting members, and constituting a cassette removably mounted on the crosspiece with possibility of movement parallel to the axis of the cylinder for the removal of the leveling crew and its implementation.
  • the support frame is made up of a plate parallel to an application face of the crosspiece and provided with a series of orifices in which are accommodated pads of substantially the same thickness as the support plate and each forming a piston.
  • the support plate can advantageously be suspended by at least one pair of rollers on two rails arranged along the crosspiece, parallel to the axis of the leveling cylinder, so as to allow removal of the cassette by rolling on said rails.

  • this support plate 4 is maintained centered and applied against the underside 51 of the cross 5 by a removable locking device 74, so as to be integral with the crosspiece 5 to resist applied efforts.
  • the housings 32 of the support members 3 are each connected with play to the plate-shaped chassis 4 by fixing rods 42 which pass through the bottom of the housing 32, this resting on the heads 43 of the rods 42 by through elastic stops 44 which hold thus the case 32 applied against the plate 4, it is say towards cross 5, without opposing slight movements in the opposite direction.
  • each box 32 is associated with a positioning cylinder 6 comprising two elements, respectively a fixed body 61 and one movable piston 62 whose position relative to body 61 is determined by an actuator 63.
  • the cylinders are of the type mechanical with backlash, the actuator 63 being a screw driven in rotation about its axis by a motor-reduction unit with encoder 64, which engages in a threaded bore of the piston 62 so as to adjust the position thereof relative to the body 61.
  • the corresponding screw jacks 6 respectively to the different support members 3 are advantageously arranged inside the cross-member 5 on which is supported by the upper leveling crew D1 and which consists of a strong beam in the form of hollow box with rectangular section, bounded by one face lower 51, one upper face 52, two lateral faces 53 and two end faces 54 the bodies 61 of the cylinders 6 being fixed on the underside 51 of the beam.
  • the support plate 4 for the active cylinder 2 and its intermediate rollers 21 extends below the face lower 51 of the cross 5, over the entire length of this one.
