Abstract: In a bar puller, pins mount serrated rollers to pivoting arms, which are mounted by additional pins to a bar puller body. The body houses movable cups positioned to compress springs in response to pivoting motion of the pivoting arms. A cover retains the springs and cups in the body. In a manufacturing process where elongated stock material needs to be positioned automatically, such as in a CNC turning center, the bar puller manipulates the elongated material in the machine by holding it rigidly so that the bar puller can move the elongated material on the axis of elongation. This is accomplished by forcing the end effectors over the material, which separates the end effectors by pivoting the arms. The geometry of the pivoting arms causes interaction with the cups and springs to generate an opposing spring force to separate the end effectors.
