ABSTRACT:
Inspection and conveyor apparatus have a pair of laterally spaced, substantially parallel endless belt conveyors engaging the top and bottom ends of cigarette packs and moving the packs through an inspection station and past a rejection station to a delivery station, electro-optical means programmed to inspect selected portions of the packs passing through the inspection station to detect faults and provide signals synchronized with incremental movement of the packs, the optics and light source of each electro-optical means being off-set within a range of 20.degree. to 70.degree. from a position normal to the surface being inspected, means for receiving signals from the electro-optical means and for providing a reject signal when a fault is detected and release means for laterally moving at least one of the endless belts away from the other when a reject signal is received to release a defective cigarette pack at the reject station.
