Abstract
A live roller conveyor is described of the type which can accumulate conveyed articles on a pass line. Article accumulation is usually automatically achieved on the pass line by disconnecting pre-selected rollers from a power source. The power source for a driven roller includes a drive wheel moveably mounted on the frame supporting the rollers and having a radial drive surface which is rotatably mounted on a shaft having its longitudinal axis spaced from the longitudinal axis of the roller such that the drive surface can be moved into frictional engagement with an end surface of a roller to rotate the roller. The drive surface on the drive wheel is preferably in the form of a tensioned belt which extends around a portion of the circumference of the drive wheel and around a spaced apart rotatable drive shaft for rotation of the drive wheel.
