Abstract
An impingement oven wherein a carrier-type conveyor passes between hot air plenums located above and below the conveyor. Horizontally adjacent plenums have their fans located in an off-set position to overhang the other one of the pair. Each plenum has a nozzle plate to direct heated air toward the conveyor so that the air flow is substantially perpendicular to the conveyor and such workpiece(s) as may be thereon. An oven module having four sets of plenums and four conveyors in the same enclosure is described. A plurality of such modules serially arranged provide a multizone oven. The oven is especially suited to heating flat workpieces of thermoplastic resin which are to be processed elsewhere into hollow objects such as containers.
