Abstract:
A device for conveying flat objects (1), held vertically, at high speed in a movement along one of their long dimensions and one after another, between processing equipment items, and in particular for conveying mail envelopes of varying size in a postal sorting installation, which device essentially comprises:a stationary baseplate (3) extending from one equipment item to the other to allow the conveyed envelopes, resting on their edge, to slide; a broad motorized endless reference belt (4) stretched over a set of vertical pulleys (7) and extending, in particular, above the baseplate, along the edge of which this belt, resting on pulleys (7) of fixed axle, extends along the conveying path between equipment items, so as to provide lateral support for the envelopes in the vertical position; a motorized endless press belt (5) mounted on a set of vertical pulleys (8) in such a way that it can be pressed against the reference belt along the conveying path between equipment items followed by this reference belt, so as to grip the envelopes introduced between the latter belt and itself at one end of the conveying path followed; a series of free and elastically deformable wheels (6), mounted on fixed vertical axles along the conveying path between equipment items, so as to come to bear against the press belt in the zone where the latter presses against the reference belt.
