ABSTRACT:
A device for feeding cigarettes to the wrapping line of a packeting machine comprises a hopper for feeding cigarettes to the machine. The hopper is divided at its lower end into outlet channels having a width substantially equal to the diameter of a cigarette, and through which the cigarettes disposed in piles descend. Along each channel there is provided, in order from the top downwards, sensor device for checking the cigarettes in succession, and at an expulsion position a device for expelling the defective cigarettes from the hopper. Along each channel there is provided cyclically operated retention mechanism for the cigarettes. This mechanism extends upstream and downstream of the expulsion position, and has two halt positions for the cigarettes. The mechanism includes two arcuate recesses in the channel which are connected via bores to a source of suction and a source of compressed air. The suction and compressed air sources are selectively connected to the recesses to either retain or expel a cigarette in the recesses.
