ABSTRACT:
Core plugs, which are intended for insertion in the ends of cores on which large rolls of paper are wound, are lifted and maneuvered into position by an apparatus having an elongated horizontal spreader beam that rides on an overhead track. The beam has support arms mounted on each end, the arms being movable horizontally on the beam by a worm gear apparatus. The support arms each carry a hook that reaches downward for grasping of axially extending stubs at the outer ends of core plugs. Each arm has a pneumatically actuated rod with a clamping block on its lower end. The blocks are projectable downward to engage the stubs and secure the core plugs in position on the hooks. Vertical movement of the plugs is provided by a hoist which raises and lowers the beam. With the plugs in place at each end, the paper roll is lifted onto a supporting cradle in position for insertion of spindles of a mill stand. This supports the roll as the paper is being unwound.
