Abstract
A metal finishing barrel having a body section 10 extending between a pair of end caps 12, that includes a sidewall comprising a plurality of wall sections 14, 16 joined edge-to-edge. In one embodiment, the wall sections are formed from a single, continuous sheet member 44, bent along lines of weakness in the form of V-shaped notches 46 that each define a relatively thin, hinge-like bridging section 46a that connects adjacent wall sections. External locking ribs 50 coengage edge portions of adjacent wall sections to maintain the sheet member in its assembled configuration. Alternately, individual wall panels 14', 16' are fabricated with beveled edge surfaces 46' and are secured in edge confronting engagement by the external locking ribs. In an alternate embodiment, an internal locking rib is employed that also serves as a tumbling rib and coengages locking grooves formed on inside surfaces of edge portions of each wall section.
