ABSTRACT:
An improved paper gripper bar is described. The upper and lower portions are made from extruded aluminum and hinge together for their entire length for greater stiffness. Two or three spring clips provide a bias for closing the bar. The paper is held between the bottom ends of the spring clips and the upper bar when the bar is in the closed position. Finally, the clips are assembled into grooves in the upper and lower portions so that no additional parts are required to maintain the gripper bar parts in their proper positions.
