Latest Patents

Hartwell holds a patent for a "Belt stabilizer for pinch belt conveyor." This invention describes a method and apparatus designed to stabilize a thin, relatively frictionless conveyor belt against lateral movement. The typical belt is constructed from fiberglass and Teflon-coated materials, mounted on rollers, one of which serves as the drive roller. The drive roller features at least one ridge positioned circumferentially adjacent to one end, allowing the belt to form a track that receives the ridge as the roller rotates. The track includes mutually spaced holes along its length, ensuring that at least two holes contact the roller during each revolution. The diameter of the ridge is less than one-half of the diameter of the hole, which effectively maintains the belt's position during operation against lateral movement relative to the rollers.
