A sheet material advancer includes a base frame with a pair of spaced-apart end plates projecting from the frame. A first cylinder is mounted between the end plates and will redirect a sheet of material from a generally vertical position to a horizontal orientation. A reciprocating cylinder is operably mounted on the base frame parallel to the first cylinder and is operable between a home position adjacent the first cylinder and an extended position spaced a predetermined distance from the first cylinder. The sheet material extends from the first cylinder around the second cylinder and then to an uptake. Pneumatic cylinders are mounted on the base frame and connected to the reciprocating cylinder so as to selectively move the reciprocating cylinder between the home and extended positions.
