ABSTRACT:
A sliding plunger with rack-shaped opposite sides controls opposite rotations of a pair of rotating sector gears, with which integrally rotate two arms extending up to the proximity of the conveying units. Connecting rods are finally interposed between said arms and said conveying units to transform the rotary motion of the arms into a corresponding translatory motion of said conveying units in opposite senses along fixed rectilinear guides transversally disposed with respect to the carton support base. The control of the sliding of the rack plunger can be given 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 corresponding to the mutual removal of the conveying units and elastical thrust means acting on the same plunger in the opposite sense. The connecting rods moreover can be provided with a succession of holes, which can be alternatively chosen to change the distance among their points of pivotment with the rotating arms and the conveying units.
