This device comprises a pair of parallel arms (1, 2) having clamps (11, 21) for clamping the packages to be transported and means for regulating separation which comprise: - a scissor mechanism (4) having two rods (41, 42) articulated to the rear end of the arms (1, 2) and carrying roller means ; - guide sections (5, 5a ...) distributed on the packaging machine, provided with a longitudinal track (51) for guiding the roller means of the scissor mechanism (4) and - actuating means suited to moving each guide section (5, 5a) and arranging the latter in a position suited to determining the separation of each pair of parallel arms (1, 2) in each area of the route of the transport device by means of a variation in longitude of the scissor mechanism (4). |
