ABSTRACT:
The apparatus lifts a stack of sheets, turns the stack, and then places the side edges of the sheets on a conveyor. The lifting device is generally Z-shaped and is supported for unidirectional rotation about a horizontal axis adjacent one end of the conveyor. Two stacks of sheets are delivered to the conveyor per revolution of said device. The sheets are fed from said conveyor to a shingling conveyor which delivers a uniform shingle to a converting machine. The shingle density is controlled by a metering gate.
