ABSTRACT:
An endless belt is supported in apparatus adjacent a wheel, and at least a portion of the belt wraps around and is in driving communication with the wheel. A head supplied with a source of negative pressure pivots in timed relation with the belt, which is movable on the perimeter of the wheel, and operates to deflect the lowermost product of a stack of flat, flexible sheet-like products to a point adjacent the wheel. When the sheet is in its deflected position adjacent the wheel, the belt is actuated to move and engage the sheet to cause the sheet to be extracted from the stack between the belt and the wheel and to be fed away from the stack. The apparatus automatically adjusts to a wide variation in the thickness of the product being fed.
