A pin oven for curing can bodies with jets of a curing medium comprising an oven chamber divided by an interior louver wall into a curing medium supply plenum chamber and a curing chamber, a plurality of spaced oven passes in said curing chamber being defined by adjacent sections of the interior wall, a series of members defining curved conveying paths between adjacent oven passes, carrier means having elements for supporting can bodies with base portion facing the interior louver wall and being arranged over the series of members to define a continuous conveying path of given centerline through each oven pass, a pair of louver members forming part of the interior wall and extending substantially the full length of each spaced oven path, each louver member being oriented at a converging angle with respect to the conveying path, and being defined by front and side walls joined at their edges to define a louver chamber, said angle being selected to direct air jets at the upper side wall of the can bodies, a series of perforations in each front wall providing a fluid path form plenum chamber to louver chamber and being spaced sufficiently close together to issue a curtain of uniformly distributed air toward the can side walls a plurality of nozzles in the interior louver wall located on both sides of the centerline along the adjacent sections of the interior louver wall and alone the curved conveying paths, said interior wall nozzles being arranged in a pattern for instantaneously confronting moving can bases with substantially the same number of nozzles for immersing the can bases in a substantially uniform air stream. |
