Abstract
Two cigarette making machines are interconnected to a single cigarette packing machine via a transfer system which uses individual conveyors to convey the cigarettes from each making machine to a single chute leading to the packing machine. The flow of cigarettes into the chute from the two conveyors is controlled by a series of switches which are activated in response to the amount of stored cigarettes in the storage of the transfer system as well as a photocell arranged above the mouth of the chute. These switches actuate a control to slow down or speed up the packer in response to the amount of stored cigarettes while the photocell controls the operation of the conveyors of the transfer system in response to the absence or presence of cigarettes at the position of the photocell.
