ABSTRACT:
A method and apparatus for monitoring the supply of cap members from a magazine or supply bin, via a channel, to the capping mechanism of a capping machine. At least one signal emitter, which is provided at the channel, generates an emitted signal that changes as the cap members move past, with a disruption signal being derived from the emitted signal if this emitted signal does not change during a specified time interval. A cycle signal is derived from the working or machine cycle of the capping machine. If no change of the emitted signal is determined in two successive cycles, the sum of which correspond to a full period of the cycle signal, the disruption signal is generated.
