<p>A compacting device for transversely bringing together fragile cylindrical products, particularly cigarettes, or similar, and in cigarette packing machines, comprises a horizontal supporting surface (4) for at least one group (1, 1', 1'') of cigarettes (S), in which the cigarettes are placed side by side and substantially parallel to each other and with their ends aligned, and two members (6, 6') to press the cigarettes against each other, between which the group of cigarettes is interposed, and which are made to oscillate, in phase and in opposite directions to each other, transversely with respect to the longitudinal axis of the cigarettes (S), between a position of approach to each other and a position of withdrawal from each other. According to the invention, the two pressing members (6, 6') are driven in a constrained mode (12, 17, 17'), known as a positive mode, with only one degree of freedom, a single common cam (12) being provided to generate the approach and withdrawal of both the pressing members (6, 6'), by interacting with a pair of rollers (17, 17'), spaced apart, for each pressing member (6, 6'). <IMAGE></p> |
