  • Patent number: 5228634
    Abstract: A novel roll loading mechanism is described which mechanically lifts a roll of web material into an operative position at the roll mounting of the printing press. This is accomplished by use of a dual chain conveyor having supports cantilevered from the chain, and synchronized to lift both ends of the core simultaneously to the printing press mount. This chain drive and the supports are selectively driven in a forward direction to lift the roll, and reversed to lower the roll to the initial pick-up position. A common drive shaft with sprockets to engage the chains is used to provide simultaneous and synchronized drive to the dual chain conveyors. A triangular configuration of the conveyor chain is used which presents an acute angle having its vertex above the press mount to assure secure position of the roll.
