ABSTRACT:
A floating feed device is adapted to be engaged by the top sheet in a rising stack and to feed the sheet downstream. The mount for the feed device is articulated, and the device includes a vacuum chamber and horizontal drive rollers. A narrow slot is formed between a guide roller of the feed device and a gate which is disposed in the plane of a stack back-up plate and which is vertically movable in said plane. A control is provided to maintain the same slot width, no matter what the articulated position of said guide roller, by automatically adjusting the gate vertically with the guide roller. The feed device is caused to articulate about its mount upon engagement by a rising stack, and such articulation causes a resultant change in the speed of the stack lift drive.
