Abstract

the present invention concerns an oven for plane hardening of glass sheets, said oven comprising a tunnel, metallic structure formed by an external and an internal grill-like envelope, both delimiting a gap filled in with insulating material. Said oven comprises one or more heating rooms and a cooling room fed with air. The oven is crossed by transport rolls that move glass sheets, wherein said rolls are tubular elements filled in with insulating material and supported externally to the structure.
