ABSTRACT:
Direct-flame apparatus for drying coatings applied to the outer surface of metal cans. The apparatus includes a conveyor adapted to advance the cans in a continuous train through a tunnel having a series of direct-flame assemblies mounted therein, whereby each can in the course of its advance is progressively heated by the assemblies to cause the cans to emerge from the tunnel in a dried state. Each assembly is constituted by a gas-fed burner element and a hood placed thereover, the element emitting a sheet of flame which impinges on the coated surface and is flanked by curtains of air issuing from the hood at a velocity serving to confine the applied heat within a limited sector of the can and to prevent flashing of the coating despite the high temperature of the flame impinging thereon.
