ABSTRACT:
A device for transferring paper rolls to and from a printing press includes a wheeled frame having a low profile configuration to permit entry into a confined space between adjacent roll stand in a bottom loading, community style web press. A pair of upright support members are attached to the moveable frame and each support member carries a roll shaft holder. A pair of arms are pivotally attached to the support members and are simultaneously moved by a hydraulic drive system. The arms are adapted to lift a paper roll by engaging the paper roll shaft. As the arms are raised, the roll rotatably moves along the arms to place the roll shaft in the holders on the upright support members. The arms are moved to a nearly vertical position in order to clear the structure of the press stand when the roll transfer device is moved into and out of the confined space between the presses. The arms also each include a rear segment for lifting the roll shaft from the holders when the arms are lowered to position the paper roll in a roll stand of a press.
