  • Training idler assembly for a conveyor system
    Patent number: 5609241
    Abstract: A training idler assembly for use with a conveyor belt which quickly responses to mis-tracking of the belt to thereby return the belt to its centered position. The idler roller is rigged through cables to hinged guide rollers which engage either side of the conveyor belt so that when the belt tracks either to the right or to the left, the respective guide roller actuates the appropriate cable to cause the idler roller to rotate about a vertical axis which, in turn, causes the belt to track back towards its center position on the idler roller.
