Abstract
Apparatus for unloading decorated cans from wire brush-type container carriers or holders mounted on a closed-loop conveyor chain moving along a path extending through a curing oven includes a plurality of retriever rods mounted on a continuous rotating wheel. Radial movement of the retriever rods is programmed so that the free end of each rod engages the closed end of a can on the outside thereof, axially moving the can from a rear pocket of the wheel to an aligned front pocket. This movement strips the can from the holder, and when the stripped can reaches a predetermined angular position of the wheel such can is directed by gravity into an output conveyor chute.
