Abstract: A method and apparatus is disclosed for aligning rolls in a feed system. The rolls are spaced at regular intervals so as to enable incorrectly positioned rolls to be turned to the correct feed position, when necessary, while they are moving forward in a feed direction. The correct position of each roll is identified by detecting the longitudinal hole through the center of the roll.
