Abstract
An apparatus for cutting stretch film or other wrapping film comprises a fixed blade and having a sharpened edge, and a pivotable anvil having a blunt edge, and a camming edge which has a concave portion and a further portion. The anvil is pivotable between an opened position relative to the blade and a closed position relative thereto. A camming roller engages the camming edge. A pneumatically powered piston-cylinder mechanism is operative for advancing the camming roller from a retracted position, through an intermediate position, to an advanced position and for retracting the camming roller in the opposite direction so as to pivot the anvil to the opened position when the camming roller is retracted to the retracted position, so as to pivot the anvil to the closed position when the camming roller is advanced to the intermediate position, and so as to press the anvil in the closed position when the camming roller is advanced from the intermediate position to the advanced position. An elongate bar having a flanged end is movably mounted upon to the frame so as to be longitudinally movable between an extended position wherein the elongate bar is capable of being wrapped by such film and a withdrawn position near the blade and anvil. A pneumatically powered piston-cylinder mechanism is operative to move the elongate bar longitudinally between the extended and withdrawn positions.
