Abstract
Method and machine for reducing the height of a box without removing a section of the material of the box and without the use of any cutting tool whatsoever, but by folding high sections of side walls towards the centre of the box. The method includes: breaking the connections between the side walls along the upper section of the vertical ridges of the box, from the height of the vertical walls of the box to the level of the top of the stack of objects previously positioned in the box, by exerting a force, directed towards the exterior of the box, on the high section of at least two of the side walls; simultaneously folding towards the exterior the high sections on which force is exerted; then folding all the high sections towards the interior of the box, in order to bring the side walls into a substantially horizontal plane.
