Abstract
An improved drive unit for accumulation live roller conveyors utilizing frictional engagement of a radial surface provided on drive wheels against the rollers is described. The drive unit includes multiple drive wheels each functioning to rotate two rollers simultaneously and each provided with a radial frictional drive surface which engages the rollers. The drive wheels are rotatably mounted in spaced and aligned relation on a support bar and the support bar is arcuately pivotable on a frame supporting the rollers towards the roller surfaces in order to selectively bring the radial drive wheel surfaces into contact with the roller surfaces.
