ABSTRACT:
An electrooptical packet control method, whereby parallelepiped packets are fed along a given route by two conveyors at least partially offset in relation to each other and cooperating with two opposite faces of the packets. Electrooptical pickup means located along the aforementioned route pick up a given number of faces on each packet as it travels along the first conveyor, and the remaining faces on the packet as it travels along the second conveyor. The resulting images are then compared with a reference image, the outcome of which comparison determines acceptance or rejection of each packet.
