Abstract
A method of separation from a stack of sheets a block of predetermined number of sheets, the method including retaining the stack so that a portion of one edge of each consecutive foremost sheet is free to bend away from the stack, directing a plane of air flow sequentially on to the foremost surfaces of a predetermined number of foremost sheets to bend at least a portion of the free edge of each of the predetermined number of foremost sheets away from the stack, separating the bent predetermined number of foremost sheets into a block and removing the block from the remaining sheets in the stack. Preferably, the plane of the air flow intersects the plane of the sheets in the stack in the range of 5.degree.-10.degree.. The plane of the air flow can be directed to bend the free edge or just the corners of sheets in the block to be separated. In one example, the stack foremost end is inclined downward and the air flow is directed upward.
