<p>This invention refers to a seam-folding system to compensate the bending of metallic containers (1) which can be applied during the manufacturing process applicable to all kind of metallic containers (1) of a shape that can be either trunco-pyramidal, prismatic, elliptical or similar to correct the bending (5) produced when the body of the container (1) is expanded and specifically during the seam-folding (4) operation to fix the bottom (2) to the sides of the container. The hook of the ends or corners of the container is housed in the bottom hook with a slight difference in length between them while the hook of the intermediate areas of the container is considerably narrower than the bottom hook. The compensation of this difference in length is performed during the seam-folding (4) operation.</p> |
