Definitions

  • the rollers 11 and 12 are nested one inside the other in a decreasing manner in the running direction of the web: thus the web is deformed by a significant amount by bending between the input rollers 11a, 12a, 11b, but very little in the exit rollers 11 m, 12m, 11 n from the exit area of the planer. In this way, the initial geometrical defects of the strip are transformed by plastification into a system of residual stresses whose amplitude decreases with that of the flexion imposed by the rollers.
  • the adjustment assemblies according to the aforementioned example of screw-nut type are actuated by the motors 19a and 19b by means of the drive shafts 17a and 17b.
  • the couplings 18a and 18b temporarily disconnect the sets of settings they connect, so as to adjust the transverse parallelism (or "skew") between the lower and upper rollers, input and output planer.
  • the adjustment of the roll nests is then carried out by means of the motors which simultaneously drive the adjustment sets at the input or at the output of leveler.
  • the subject of the invention is also a method of calibrating a roller planer using the instrumented bar device defined above, characterized in that two such measuring rods comprising an instrumented thin blade are placed near the bearings in the planeuse, the ramps against against supports being completely lowered, the series of lower and upper rollers are brought closer to one another by action on the clamping control means so as to exert a force on said bars measurement, this reference force corresponding to the planar strips of thickness, limit and modulus of elasticity lowest likely to be processed on the leveler, said blade being in a state of elastic deformation.
  • the strain gauges are measured by means of said extensometers to deduce a reference air gap, the swaying and tilting of said planer, and if necessary, make corrections based on these results.
  • FIG. 6 shows an instrumented bar device according to the invention and its positioning in a roller planer.
  • FIG. 7 illustrates a method of fixing the thin blade on a stud of the instrumented bar.
  • the general dimensioning of the bar is made from the leveling conditions of the range of products that require the least effort (minimal bending of the gliding rollers)
  • a thin blade 82 rests on the pads 81. The presence of this blade simulates that of a thin product in line contact with pads of a hardness comparable to that of glider rolls. The total length of this blade is greater than the distance between the axis of the first and the last roller.
  • the width of the blade, defined so that the support assembly has sufficient rigidity, does not exceed the width of a counter-support.
  • the thin blade is secured to the bar by attachment to a single central stud of the bar, this to allow free deformation of the blade on either side of the fixing point during tightening.
  • extensometers 83a and 83b for example strain gauges, deformation optical fiber gauges measuring the variation in length of a Fabry-Perot cavity, or any other means for measuring the local deflection of the thin blade
  • extensometers 83a and 83b for example strain gauges, deformation optical fiber gauges measuring the variation in length of a Fabry-Perot cavity, or any other means for measuring the local deflection of the thin blade
  • the extensometers are preferentially localized on the extension face of the thin strip at the fourth roller (thus on the entry side of the leveler) and N-3 the roller (exit side of the planer).
  • the extensometers are placed in the center of the blade, in line with the two rollers mentioned above, to measure the local extremum of bending deformation.
  • This step is repeated by laterally moving the bars to the right of two other counter-supports 21, as many times as necessary, until calibration of the entirety of the counter-supports 21.
  • the first step remains identical to that described above, whereas the next step consists in arranging a bar 8 under each ramp 21.
  • FIG. 8 illustrates the transverse variation of the clamping measured at the input (E) and the output (S) of this planer by means of bars with an instrumented blade, the bending ramps being completely lowered.
  • This first step makes it possible to identify a bending of the rollers under load, as well as a kinking of the cassette of the planer.
