  • Patent number: 4790428
    Abstract: A conveyor belt guide apparatus is provided in which a guide roller is attached on either side of a conveyor belt and contacts the same. The guide roller is designed to rotate by the force of the conveyor belt when the conveyor belt moves off center. Spiral rings are positioned on the guide rollers in such a manner that the rings have a vertical pitch in the direction in which the conveyor belt causes the guide roller to rotate. When the conveyor belt attempts to climb up the guide roller, it engages the spiral rings and is forced back down. In this manner, the conveyor belt is prevented from climbing above the guide rollers and is adjusted back to its normal position.
