ABSTRACT:
A device for forming separate batches of flat objects, such as folded box blanks, from a flow of blanks received from a delivery station of a processing machines, such as a folder-gluer, includes a belt conveyor, a counting device, and a movable stop which is movable parallel to the belt surface and also movable vertical to the belt surface with a control device to move the stop in response to sensed conditions. The control device controls a drive arrangement for the belt conveyor so that the speed of the belt conveyor can be driven at a greater rate than the speed of discharge from the delivery station during a selected period for separating the batch of blanks from the remaining flow.
