Definitions

  • the present invention relates to strip slitting installations and it relates more particularly to a device making it possible to ensure a counter-traction uniformly distributed over a set of strips which is present at the winding, on the same drum.
  • Slitting wide strips of a generally metallic material, consists in cutting a strip appearing in a reel, lengthwise, that is to say that one starts from a long sheet, in large width , to form leaves of the same length but in small width.
  • a conventional slitting installation generally comprises, as indicated in FIG. 1 of the attached drawing: - an unwinder 1, - a deflector 2, - a shear, for example with multiple knurls 3, - a reel 4.
  • each of the coils formed must be separated from its neighbor by mechanical means to avoid overlapping of the bands. If this separation occurs while the bands are under tension, the edges of the split strips are generally damaged.
  • the present invention proposes to provide a device making it possible first of all to solve the difficulties mentioned above and to allow the production of coils for winding, without telescoping and also compact.
  • the device of the invention is necessarily used on a line called "with loop", the kinematics of which has been known for a long time, that is to say that the shears cut the strips into a pit, before they are present to the winding.
  • This technique has the effect of facilitating the separation of the strips while they are tension free at the outlet of the pit.
  • This separation is effected by a straight or rotating separator, which is a known assembly, designated by the reference 5 in FIG. 1.
  • Band slitting systems which include a tensioning device making it possible to brake simultaneously and without friction a set of bands which is wound on the same drum, in which the necessary braking force is transmitted to two layers endless belts between which the strips of so that the belts can have different speeds, respectively equal to the speeds of the split strips to be braked.
  • the invention proposes to remedy these drawbacks by providing a strip slitting installation comprising a tensioning device making it possible to brake simultaneously and without friction a set of strips presenting themselves for winding on the same drum, in which the force necessary braking is transmitted to two plies of endless belts between which pass the slit belts so that the belts can have different speeds, respectively equal to the speeds of the slit belts to be braked,
  • this installation being characterized in that the effort of braking is on the one hand applied directly to the belts of the upper ply via an upper clamping plate and, on the other hand on the lower ply via a lower clamping plate constituted by a plurality of tubes including the number and the surface upper are identical to those of the belts, these tubes being covered with a wear sheet of great hardness, transmitting the braking force to the belts of the lower ply.
  • the wear sheet forming part of the lower clamping plate is a sheet of stainless steel and it is stretched longitudinally over the tubes forming part of this lower plate, the assembly being carried out so as to be able to easily change this wear sheet.
  • the upper braking plate is produced in the form of a hollow box in which circulates a cooling fluid, in particular water and the tubes constituting the lower clamping plate have a section straight square or rectangular and they are traversed by a coolant, such as water.
  • the clamping force is transmitted to the two braking plates, upper and lower, by means of an inflatable chamber interposed under said lower plate and the frame of the installation, this chamber preferably being of tonic form, made of a deformable polymer and supplied by a compressed air generator, the pressure of which is adjusted to vary the amount of braking at will.
  • the device object of this invention there is designated by reference 6 the device object of this invention.
  • the slit strips 8 are pinched by sets of belts 11, 11 ′ then deflected by a deflection roller 7 before being presented on the reel 4
  • the belts of each of the plies of belts 11 and 11 ′ are constituted by a plurality of elements of small width, for example of the order of 15 to 50 mm as required.
  • These belts are wound on pulleys 9, 10 and 9 ′, 10 ′ respectively.
  • the belts are guided laterally by any suitable known device so as to obtain correct winding.
  • the invention provides means for transmitting a braking force to the two plies of belts 11 and 11 ′ making it possible to brake simultaneously and without friction all of the slit bands 8 which are present at the winding on the drum 4. This braking or friction force is applied to the belts themselves, in line with the tightening of the latter on the bands 8.
  • This braking device is shown in detail in Figures 2 and 3. It essentially comprises an upper clamping plate 12 and a lower clamping plate 13, 16.
  • the upper clamping plate 12 is produced in the form of a box hollow in which a cooling fluid such as water can circulate, the lower flat surface of this box 12, located opposite the ply of belts 11 coming to apply directly on the upper face of these belts 11 to transmit the braking force by these belts with the split bands 8.
  • the lower clamping plate comprises a plurality of tubes such as 13, the number and the upper surface of which (active braking surface) are identical to those of the belts of the ply 11 ′ (as can be seen in Figure 3), the tubes 13 being covered with a wear sheet 16, of great hardness, intended to transmit the braking force to the belts of the ply 11 ′.
  • This braking force is applied to the tubes 13 by means of an inflatable membrane or chamber 14 interposed between the tubes 13 and the frame 17 'of the device.
  • the tubes 13 have a square cross section, the upper surface of which corresponds to that of the belts of the ply 11 ′ to be braked and they are traversed by a cooling fluid, in particular water.
  • the wear sheet 16 can be produced in the form of a stainless steel sheet, of small thickness, having a good coefficient of friction and a high hardness, for example of 62 HRC. This wear sheet is stretched longitudinally on the tubes 16, as can be seen in Figures 2 and 3, this assembly being carried out so as to be able to easily change this wear sheet.
  • the inflatable chamber 14 which transmits the braking force to the upper and lower braking plates is preferably toroidal in shape and is made in particular from deformable polymer.
  • This chamber can be inflated using compressed air supplied by a generator, the pressure of which is adjusted so as to vary the value of the braking at will.
  • the particular configuration of the lower braking plate allows easy adaptation to the different thicknesses of bands 8 to be braked individually and then wound on the drum 4.
  • the disadvantage mentioned above of very uneven wear of the parts making up the braking plates of the installations currently carried out, do not exist in the device according to the invention described above, thanks to the original design of the lower braking plate, and thus excellent resistance of the belts 11 and 11 ′ is obtained, making it possible to double and even triple the operating time before rectification of these belts.
