Device for driving load conveyors or transporters

Device for driving load conveyors or transporters, in the form of a driving and guiding means (4), which is integrated in a line of conveyors or transporters (1 and 2) and extends along the longitudinal axis of said conveyors or transporters (1 and 2), perpendicularly to their plane, and which consists essentially of the combination of a driving belt (5), arranged along at least one longitudinal edge or in the extension of longitudinal edges of at least one conveyor or transporter (1 or 2), or of two successive conveyors and transporters (1 and 2), and of a guide (6) for applying loads (3) against the driving belt (5), arranged along the opposite longitudinal edge(s), where the driving belt (5) and the guide (6) for applying the load (3) are arranged, with respect to chains with palettes forming the conveyors or transporters (1 and 2), in such a way that the distance between their opposite face is slightly smaller than the width of the loads (3) transported by said conveyors or transporters (1 and 2), characterized in that the driving belt (5) is a belt with a cover made of rubber or of another material with a high coefficient of friction, and the guide (6) for applying loads (3) is in the form of a rigid blade with ends that are slightly curved inward in the direction opposite the driving belt (5), and with a low coefficient of friction, where said rigid blade is mounted on supports (7) for fixation to the corresponding side of the conveyors or transporters (1 and/or 2), with interposition of means presenting controlled elastic deformation.
