Abstract: The invention relates to a width-adjusting device for conveyor corridor(s), comprising a wide gear-reduction mechanism connected to the frame (5) of said conveyor, wherein said mechanism is arranged between the control shaft (12) and the wall(s) of said corridor. The device includes: a final drive capable of reverse operation and consisting of said control shaft (12) in the form of an endless screw and of a toothed wheel (11); and a system for controlling at least one of the walls of said corridor, consisting of an endless screw (13) and a nut, the endless screw being mobile or fixed relative to said toothed wheel (11). The shaft (12) of the final drive is a flexible shaft having a long length and engaging with the tension-retaining system (20) for absorbing the pulling and pushing forces in the rotation direction thereof.

Abstract: The invention is an improvement to a conveying equipment that includes at least one curved corridor in which runs a queue of products moved by an endless mobile belt, said corridor being defined by: a first wall connected to the frame and having a first fixed curvature radius and a second wall mobile relative to said frame and having a second curvature radius that varies based on the products, said second mobile wall including: a guiding profile that may comprise several members, used as a friction surface and extending from an inlet up to an outlet of said curved corridor opposite said first fixed wall; a structure bearing said guiding profile, the structure including several segments connected to moving means, said segments being in abutment and distributed between the inlet and the outlet of the curved corridor and being movably housed in said guiding profile.
