ABSTRACT:
An apparatus is described for controlling the sequences of operations executed at the various work stations. At each work station there is provided detecting means arranged for detecting the correct completion of an operation, e.g. the correct positioning of a part in a support such as a case for making a cartridge, and generating a fault signal when the operation is not correctly completed. The fault signal is written into shift register means and shifted in response to a timed control signal, the successive states of this shift register means being compared with a reference signal representing the number of steps along the path between that work station and the next. When the state of the shift register means is coincident with the reference signal, an inhibit signal is produced for inhibiting the operation at at least one next work station.
