ABSTRACT:
A method for grouping boxes, after stopping the head box of a train line, includes transversally displacing a last box of the train line with respect to the first box of the upstream line waiting for grouping and introducing a stop motion unit for holding the upstream line into the space cleared by the last box. The conveyor device includes an endless lateral rail which is used for guiding boxes and is laterally shifted at a length corresponding to at least the box longitudinal dimension and forms something like a funnel at the location of the last box of the train and a device, which is used for transversally displacing the last box by pushing it into the funnel and includes the stop motion unit holding the first box of the upstream line.
