ABSTRACT:
A tobacco stream which is built at the underside of the lower reach of an endless foraminous belt conveyor is monitored by a detector which generates a signal in response to detection of excessive accumulations of tobacco in the stream. Such signals are used to interrupt the delivery of a tobacco flow to the belt conveyor, to arrest the device which supplies tobacco that forms the flow, to remove tobacco from the belt conveyor, and to restart the delivery of tobacco to the belt conveyor, to restart the tobacco supplying device, and to deactivate the tobacco removing device when the stream is removed from the belt conveyor. The interruption of delivery involves diversion of tobacco into a path which leads to a magazine. The tobacco removing device can include a valve which deactivates a suction chamber serving to attract tobacco to the belt conveyor, a mechanical tobacco remover and/or one or more nozzles which serve to blow compressed air against tobacco on the belt conveyor.
