Abstract
A composite ring member comprises an annular ring member and an annular reinforcing ring member welded to the external peripheral portion of the annular ring member. The annular ring member comprises a tubular stock member, having a substantially rectangular or square-shaped cross-sectional configuration, which is bent into the form of the annular ring member and the free end portions thereof are welded together. In this manner, excessive waste of material in forming conventional ring members, wherein such conventional ring members are cut out from square plates, is eliminated. Segmentally-configured gusset plate members are welded to diametrically opposite internal peripheral portions of the annular ring member so as to respectively support a film roll carriage and dispensing assembly and a counterbalancing mechanism.
