Abstract
Sheet separating apparatus for separating the bottom sheet from a sheet stack while at the same time adapted to adjust to any non-uniformity in thickness of portions of the sheet as each sheet enters a nip between a friction member and a sheet conveyor of substantial breadth. The sheet separating apparatus includes a broad friction member which is biased toward engagement with a broad, load distributing conveyor which transports the sheet material. The friction member is supported in such a manner that it can tilt about an axis which is parallel to the sheet path, and thus adjust itself in accordance with any variations in thickness of that portion of the sheet which the conveyor encounters as it enters the nip between the friction member and the conveyor. This arrangement causes a uniform pressure to be generated by the various portions of the friction member upon the various portions of the conveyor, and thereby to have a more uniform effect upon the portions of the sheets as they enter the nip.
