Abstract: A pin oven is disclosed for curing coated or decorated can bodies travelling in a serpentine path wtih jets of a curing medium. The pin oven chamber is divided by an interior louver wall into a curing medium supply plenum chamber and a curing chamber. The cans move through the oven on a pin conveyor and jet nozzles in the louver wall are arranged in a pattern for instantaneously confronting moving can bodies with substantially the same number of nozzles for immersing the can bases in a substantially uniform air stream in order to minimize can flip-flopping on the pin conveyor in order to achieve oven speeds in excess of 1000-1200 cans per minute. The louver wall is provided with chambers for uniformly distributing the pressure and velocity of air jets to reduce the tendency of cans to pulsate as they pass through the oven. The louver walls are of modular construction for application of the oven to a variety of can sizes and decorating or coating technologies.
