Device for storage of flat objects

In a device for forming and storing a stack of flat objects each having a plurality of edges, in a box open on one face, closed on the opposite face, and having a plurality of additional faces extending between said opposite and open faces to define sides, said flat objects being stacked substantially perpendicularly to said opposite face and against one of said sides defining a stacking surface, said objects arriving individually from a processing device in a substantially vertical plane substantially perpendicular to said opposite face and an adjacent side, and remote from said stacking surface and at a certain speed, the improvement comprising:

• said box being positioned with respect to said processing device so that objects arrive along a path of travel forming an acute angle with said opposite face;
• a stop situated substantially in the plane of said adjacent side of the box and positioned to receive the impact of part of the leading edge of an arriving object, said stop acting on said object to create a couple of rotation in its plane, so that an edge of said object directed towards said opposite face and defining a lower edge is urged against the opposite face of the box;
• and
• said processing device being situated at a sufficient height with respect to said opposite face so that each flat object, as soon as its lower edge is resting on said opposite face retains its perpendicular orientation thereto and moves against the stack already formed.
