Abstract
A device for eliminating defective flat objects, which are being conveyed individually and at a distance from each other, preferably tubular segments or sack workpieces during the production of sacks, and for forming stacks of flawless objects, said device comprising a twin belt conveyor, which conveys the objects and comprises groups of continuous belts that are spaced apart and cycle parallel to each other; comprising a system for scanning the objects; and comprising a shunt, which eliminates the objects that are recognized to be defective. Behind the discharge end of the twin belt conveyor there is a stack shaft with an intermediate stacker plate, and before the discharge end there is a rake-shaped deflecting element, which forms the shunt and can be moved between the bottom conveying run of the twin belt conveyor and which guides the objects, recognized to be defective, into a place of deposit, arranged above the stack shaft.
