ABSTRACT:
Method and device for pivoting plate elements travelling on a flat conveyor, the conveyor being provided with two parallel left and right paths, respective driven at different speeds. The paths define between them a separating line on which the plate elements are rotated around an axis by application of each of the two path speeds on a left portion of the plate element and on a right portion of the plate element defined by the separating line. The method involves maintaining the barycenter of each plate element sufficiently close to the separating line to extend the effect of the rotation applied to these plate elements.
