Abstract:
1. A guidance surface designed to carry a transporting endless belt, this guidance surface being characterized in that the curvature of the guidance surface is determined by: a horizontal roller; and two lateral surfaces fixed in relation to movement of the endless belt and located on either side of the aforementioned roller, where each lateral surface is curved, forms a continuous wall surface along a longitudinal axis of the endless belt throughout the entire length of the belt, and, along with the roller, forms a portion of a bearing surface adapted to support and extend beyond the belt and, at least locally, at least one of the lateral surfaces is fixed to a chassis by rapid securing devices so as to provide an access door to the belt, and where at least one of the lateral surfaces is rotatably or slidably supported by guidance devices adapted to constrain movement of the lateral surface between two positions, which have been determined beforehand, to provide the access door.
