In a feed device comprising a chute divided into channels through which the cigarettes descend intermittently in stacks on their way to a wrapping line, the quality of the single cigarettes is controlled by sensors associated with the chute, whereupon any substandard cigarettes are ejected by a device interlocked to the sensors. The loose cigarettes are retained and aligned inside the channels by an alternating mechanism stationed above the ejection device, which is able to adjust the axial position of the cigarettes in relation to the sensors and to generate an axial supporting action, applied cyclically to the part of the descending stack immediately above the ejection station, of which the timing is fixed in relation to the operating cycle of the ejection device.
