<p>A machine for packaging fragile cylindrical products, particularly cigarettes, comprising a unit (1, 2, 3) for forming and transporting ordered groups of cigarettes, and a station (T) for transferring the groups to a following processing unit (5) by means (8, 9, 10, 11, 12, 13, 16, 17, 18) synchronized with the forming and transporting unit (1, 2, 3). Means (6) of checking the correct formation of the ordered groups of cigarettes are provided before the transfer station (T). Between the checking means and the station (T) there are provided ejection means (8', 9', 10', 11', 12', 13', 16', 17', 18') which are identical to the transfer means and are operated in phase by a single common operating mechanism (15, 20) in the transfer and ejection strokes. The ejection means (8', 9', 10', 11', 12', 13', 16', 17', 18') are always operated in conjunction with the transfer means and they at least are additionally movable, under the control of the checking means (6), transversely with respect to the ejection stroke to a position where they do not interfere with the groups of cigarettes. <IMAGE></p> |
