ABSTRACT:
Apparatus for transferring and positioning paper reams onto the feed conveyor of paper ream wrapping machines, comprising a lever member hinged at one end and connected with its opposite end to a gripper assembly, a connecting rod member having its ends respectively mounted pivotally to the lever member and to one arm of a crank lever member actuated to impart to the lever member an oscillating movement. A control means is provided for shifting the pivot between the lever member and the crank lever member and the rotation axis of the crank lever member parallel to itself, such as to vary the amplitude of the oscillation angle of the lever member according to the size of the paper reams to be transferred to the conveyor and selectively cause the angle to lead and lag so that the stroke limits of the lever member happen to coincide with the fixed positions respectively of ream pick up and ream release along a predetermined conveyor axis.
