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 platform which supports a pair of cantilevered contact rollers journaled at opposing ends of the platform. When the platform is vertically reciprocated by the force-producing device, the contact rollers in driving engagement with a drive belt are forced upward, placing the drive belt into driving contact with the conveying rollers.
