ABSTRACT:
The quality control device disclosed is designed to detect the correct shape of packets, especially crush type packs of cigarettes, and comprises transducers, excited by proximity of a sheet of tin foil, and photoelectric cells which check that the side folds of the wrapping are properly stuck down; both types of component are structured such as to transmit an error signal to circuits triggering operation of a knockout power source used to eject any defective packets.
