Abstract
An endless conveyor belt has teeth with drive faces raked away from the direction of travel. The belt can be driven by a drive pulley having sheaves with drive faces raked toward the direction of travel. The drive faces on the sheaves engage the drive faces on the teeth to move the belt and the raked angle tends to pull the belt inwardly. A stationary foot assists removing a driven tooth from its corresponding sheave.
