Abstract: Disclosed apparatus sort unequally dimensioned veneer sections or other objects which are successively conveyed in a transit direction by a conveyor in parallel to their planes. A series of sensors are mounted at equal mutual distances across the conveyor in a row extending transversely to the transit direction and generate sensor signals in response to successively conveyed objects. The sensor signals are analyzed and the extents of the conveyed objects are tested on the basis of the analyzed sensor signals, preferably with the aid of predetermined nominal values. The conveyed objects are sorted in accordance with their tested extents.
