Abstract
A radiant oven for treating a web of material has oven chambers, electric radiant heaters and buffer plates. The material treated in the oven chamber is isolated from the heaters by the buffer plates. The buffer plates also prevent solvent vapors from reaching the heaters. This invention allows the use of nonclassified electric radiant heaters to treat material in a classified oven chamber.
