Abstract
A metering drum assembly for the rotation of can-shaped objects over a surface from a first to second location. The drum device employs an inner, hollow, non-rotating, cylindrical member and an outer, hollow, rotating, cylindrical member, each cylindrical member being oriented about the same longitudinal axis. A vacuum is drawn within the inner, hollow, non-rotating, cylindrical member pulling air through the perforated surface of the outer, hollow, rotating, cylindrical member only across a defined segment of orientation.
