Abstract
A contact assembly for an accumulation conveyor includes a support member having a cavity dimensioned to receive a force producing device. A contact member is positioned between the force producing device and the conveying rollers and reciprocates with respect to the conveying rollers. The contact member includes a wheel assembly which, when vertically reciprocated by the force-producing device, places the drive belt into driving contact with the conveying rollers. The wheel assembly is configured to move in a substantially transverse direction to the direction of movement of the drive belt to maintain alignment between the drive belt and the contact assembly.
