ABSTRACT OF THE DISCLOSURE A sliding plunger with rack-shaped opposed sides controls opposite rotations of a pair of rotating sector gears with which integrally rotate two arms extending towards the conveying units. Connecting rods are disposed between the arms and conveying units to transform the rotary motion of the arms into a corresponding translatory motion of the conveying units in opposite senses along fixed rectilinear guides transversally disposed with respect to the carton support base. The sliding of the rack plunger can be controlled by a pneumatic cylinder or by a hand-control lever. There can be provided adjustable means for limiting the sliding plunger stroke in the sense correspond- ing to the mutual removal of the conveying units and resilient thrust means acting on the plunger in the opposite sense.
