ABSTRACT:
A cigarette hopper, especially for a packing machine, has a number of flow channels (6) incorporating restraining devices to arrest cigarettes which are faulty, e.g. in size, shape or orientation, thereby preventing the formation of defective cigarette bundles. The lower ends of the channels (22) may be curved to catch non-horizontal cigarettes (C3), and may include photo-cell devices (FIG. 3) which detect and arrest inadequately filled cigarettes and which additionally serve to monitor the flow of cigarettes so that the machine operator can receive a fault warning.
