Abstract

This device comprises a pair of parallel arms (1, 2) having clamps (11, 21) for clamping the packages (E) 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 (46, 47);—guide sections (5, 5a . . . ) distributed on the packaging machine, provided with a longitudinal track (51) for guiding the roller means (46, 47) of the scissor mechanism (4) and—actuating means (7) 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).
