Definitions

  • the invention refers to a seam-folding system to compensate the bending of metallic containers the aim of which is to prevent the usual bending that normally appears in the metallic containers during the expansion operations carried out to obtaining or manufacturing such containers.
  • the seam-folding system to compensate the bending can be applied to all kind of metallic containers of a shape that can be either trunco-pyramidal, parallelopipedic, elliptical, etc.
  • the object of the invention is to absorb or compensate the differences in the length between the hooks at the corners and those intermediate ones produced during the seam-folding of the container and its bottom.
  • the preconized seam-folding system to compensate the bending achieves that during the seam-folding operation the defect mentioned-above is corrected which, in turn, will save the operations 1 and 3 referred to above and which are prior to the seam-folding operation.
  • operation 2 As far as operation 2 is concerned, it enables a more uniform and straight configuration of the container wall which, in turn, enables to better store such containers.
  • Figure 1 shows a schematic view of the side of a container with one part seam-folded and the opposite one non-seam-folded. In this latter case the relevant bending can be noticed.
  • Figure 2 shows a plan view of a rectangular container with the seam-folding flange presenting different widths in the intermediate areas and in the corners.
  • Figure 3 shows in detail a section of a conventional seam-folding with no possibility of compensating the seam-folding since the hook and the loop where it is housed have the same length.
  • Figures 4 and 5 show section views of a compensating seam-folding made in accordance with the object of this invention.
  • a metallic container (1) presents a bottom (2) and a perimetric flange (3) for seam-folding (4) purposes represented in another area of the same figure which also shows the bending (5) before the seam-folding.
  • Figures 4 and 5 show the sections of the compensating seam-folding according to the invention, while figure 3 shows the conventional seam-folding with no differences of length between its hooks, i.e. those which intervene in the seam-folding between such conventional container (1') and the relevant bottom (2').
  • the configuration of the new seam-folding, according to figures 4 and 5, enables to reduce the height of the hook (6') by means of corrugations that shorten its length and, on the other hand, the hook (7') should be kept completely straight, compressed and compact to avoid that the bottom (2) is detached from the body (1) while keeping the referred water-tightness level.
