摘要： A method and apparatus are described for stabilizing a thin, relatively frictionless conveyor belt against lateral movement. The typical belt is made of fiberglass and Teflon-coated and is mounted on rollers, one of which is a drive roller. The drive roller is equipped with at least one ridge disposed circumferentially adjacent an end thereof and the belt forms a track which receives the ridge as the roller rotates. The track, in turn, has mutually spaced holes along its length. The holes are disposed at least so that two contact the roller during each revolution, and the diameter of the ridge is less than one-half of the diameter of the hole. This tracking device then will maintain the belt during operation against lateral movement relative to the rollers.
