Abstract
An accumulation conveyor includes an endless drive belt that is juxtaposed with a multiplicity of rollers and at least one control device for selectively moving the drive belt into driving engagement with the rollers. The drive belt has a high-friction face engaging the rollers and a low-friction backing engaging the control device. The control device includes a support member having a cavity formed therein and a force-producing device in the cavity. A contact member is positioned between the force-producing device and rollers and reciprocates with respect to the rollers. A signal manifold is mounted to the support member and interconnects with the force-producing device and with signal manifolds of adjacent control devices.
