Abstract: Conveyors feed veneer sheets to a plywood assembly station in sequence for assembly. Sometimes two veneer sheets, one superposed upon another, are fed on one conveyor. Such a condition is automatically remedied by a veneer sheet separator formed by the conveyor and appurtenant equipment. The condition is detected automatically by sensing means which activate control means that are subsequently operated by a veneer sheet reaching a position on the conveyor and when operated actuate a vacuum head. One veneer sheet is gripped by the vacuum head while the other veneer sheet is forced downstream by the conveyor causing separation by shearing action between the veneer sheets.

Abstract: In plywood layup apparatus, veneer sheets are fed from a vertical stack onto a horizontal conveyor by a movable vacuum head that grips the uppermost veneer sheet in the stack and shifts it towards the conveyor. A pair of pinch rollers are positioned between the vacuum head and conveyor to separate a veneer sheet from the vacuum head by gripping and driving the veneer sheet forward onto the conveyor. Sometimes two veneer sheets, one superposed upon another, are fed between the pinch rollers by the vacuum head. This condition is detected automatically by sensing means which activate controls for lifting the upper pinch roller and holding the vacuum head in a sheet-feeding position. Friction force of the lower pinch roller acts on the lower veneer sheet only. The lower veneer sheet is driven forward onto the conveyor but the upper veneer sheet is held stationary by the vacuum head. After the lower veneer sheet has been separated and spaced from the upper veneer sheet, the upper pinch roller is lowered, forcing the upper veneer sheet into driving contact with the lower pinch roller. Thus, the upper veneer sheet is separated from the vacuum head and driven forward onto the conveyor.
