Definitions

  • the present invention relates to a packaging for a convex shape obtained from a pleated thin sheet of the kind described in French patent application No. 86.03956 of March 17, 86, and it relates more particularly to the method of fixing the plies together. .
  • This type of paper is generally used in combination with a layer of plastic material, which coats one of its faces, and which gives it a certain number of additional properties such as the solidity, the water and fat tightness.
  • the layer of plastic material can consist for example of polyethylene which is hot deposited by extrusion through a die, but the plastic material can also be brought in the form of a thin film which is fixed by gluing to the paper.
  • it is a polyethylene and paper complex and that it is pleated, as indicated in said patent application, there is between two successive plies on one side a paper side against a paper side, and the other side a coated side against a coated side.
  • the invention consists in providing solutions to this welding problem in order either to reduce the forces which are supported by the welded part of the fold, or to transfer them partially elsewhere, or to make a combination of the two.
  • Fig. 1 of the folds (2) is to size the packaging, according to said patent, so that during assembly the tensions remain low. This is obtained by the shape of the folds (2) combined with the distance (3) between the welds (1). If the packaging is correctly adjusted according to the terms of the said patent, we note in particular that having deployed the pleating around the convex object to be packaged, we experience difficulties when, having made a complete revolution of the convex object , we proceed to overlapping of the first layer by the second because the volume has changed, it has increased in the thickness of the packaging itself. It is therefore necessary that the part (4) Fig.
  • the attached sheet (12) is a strip projecting sufficiently on each side of the weld (15) so that the forces imparted to the weld (15) are not fully transmitted to the edge of the strip (12) which could cause it to tear .
  • the welds (1) as well as the attached strip (16) then work in shear which is very favorable to good resistance of the assembly.
  • This presoldering can be done at the time of pressing the plies, insofar as the pressing cylinder has heated and temperature controlled zones.
  • This type of fixing of the folds by folding the edges does not make it possible to have, beyond the weld (23) and the edge (25), a zone called “C” in the said patent application premising the recovery of the central surface of the convex body to be covered and delimited by the weld (23) of the folds (24).
  • distance "M" (26) between the welds (23), the value of which is determined, in said patent application, as a function of the main dimensions of the convex object to be packaged, the distance between the edges ( 25).
  • the cutting is made to give the pleated packaging before folding the edges and welding the shape of a trapezoid. Otherwise we would be left with an excess of paper, turned inside out, which could disturb the assembly. In the latter case, there is a crossover of folds at the time of welding, which is favorable to the solidity of the fixing.
