Definitions

  • the invention relates to a machine for the continuous forming of a tubular profile consisting of several strips glued together, these strips being made of fibrous, cellulosic, metallic, plastic and other materials allowing the carrying out of a forming process according to which the assembly of the strips, offset laterally with respect to each other and previously coated with glue on at least one of their faces, is produced initially over a small width and then extended to the entire perimeter of the tubular section being formed by helical progression of this assembly width, helical progression constituted by the combination, on the one hand, of the lateral extension of the assembly width and, on the other hand, of the continuous advance of all of the bands, this machine comprising a gluing station, a press, a forming device, a train of pressure diabolos, a cutting device and a discharge device.
  • the belt By giving the drums a certain angular position, the belt describes a helical movement causing, on the one hand, a helical winding of the various strips of metal and other paper previously provided with a layer of glue and, on the other hand, the continuous advance of the tubular element on the spindle.
  • This machine comprises a multiple cutting device subjected to a displacement in the axis of advance of the tubular element, therefore the variable advance and cutting speeds are synchronized with the speed of advance of the tubular element by l 'Intermediate drive and control means requested by the forming means of said tubular member.
  • Document FR-A-2 370 581 discloses a practically identical machine provided with a cutting device for tubular elements made of cardboard and similar materials comprising control means urged by pins arranged on the tubular element provided labels respectively by the front edge of said tubular element actuating a device for translating the carriage provided with at least one cutting element, the speed of advance of which is regulated by a synchronization assembly.
  • control means are a guide gun provided with a locating means such as a photoelectric cell moving along a groove produced in said gun by manual adjustment and / or by servo-control by the through a micromotor.
  • the process described in this patent consists in continuously bringing in several superimposed strips of paper whose edges are offset laterally and gradually.
  • Liquid adhesive is applied to the surfaces of the strips with the intention of making them adhere to each other.
  • the bands are compressed together to form a continuous multi-ply band having pinnate or offset edges in opposite directions while continuing the continuous movement of the multi-ply band.
  • the multi-ply tape is gradually shaped into a tube when the adhesive between the plies is wet. We butt the edges offset in opposite directions to form a continuous tube of uniform thickness over the length. Heat is applied to the tube while moving it longitudinally and maintaining its tubular shape to force the adhesive to harden and maintain said tubular shape, then the continuous tube is cut into lengths of tubular bodies.
  • the machine further comprises a press to which the different bands are then directed.
  • the press has a lower roller and an upper roller.
  • the assembly of the different strips is provided over their entire width to form a compact strip or with multiple pleats, the plies of which adhere to one another in a superimposed state.

  • the tube passes through a cutting device comprising a circular saw driven by a motor mounted on a carriage moving longitudinally at the same speed as that of the tube, which makes it possible to cut the tube into unitary elements which are evacuated from the machine by an evacuation device with an endless belt conveyor.
  • the circular saw cutting the tube must have a radius greater than the diameter of the tube. Therefore, the diameter of the tube is limited because it is not possible to give the circular saw too large a diameter.

Likewise, the clamps 211 to 213 have an internal face 217 having a shape allowing the clamps 211 to 213 to match the different external faces of the profile.
