Abstract: An apparatus is disclosed for lifting and moving large rolls of material, such as sheet material, which define a central core. The apparatus includes a wheeled frame, and a pair of guide ways that extend parallel to one another and across the frame. A lifting arm defines a lifting flange at one end, is rotatable about an axis oriented generally parallel to the guide ways, and is coupled at an end opposite of the lifting flange to one of the guide ways. An actuator couples the lifting arm to the other guide way, and rotates the lifting arm about the axis oriented generally parallel to the guide ways in order to move the lifting arm between raised and lowered positions. The lifting arm is slidable along the guide ways to permit the lifting flange to be positioned in a hollow core of a roll. Sliding movement of the lifting arm along the guide ways is selectively permitted by a brake mechanism including a brake pad in selective engagement with a guide way.

Abstract: A conveyor is mounted on the upper surface of an elongated frame. At one end of the conveyor is provided a retriever assembly for retrieving a stack of material as from the exit bin or tray of a printer or copier. The retriever has elongated fingers sandwiched between runs of the conveyor. These fingers are moved horizontally and vertically so as to move out from the conveyor, pick up a stack of material, bring it back and deposit it on the conveyor. Independent motor operated mechanism effects this vertical and horizontal movement of the fingers. The conveyor is of sufficient length to store several stacks of material and operation of the conveyor and the retriever is controlled to retrieve and store the stacked material.
