<p>The invention relates to an unfoldable removable closing device for a furnace with open chambers with progressive heating, intended to interrupt the circulation of air between each of the heating partitions of a chamber and the corresponding partitions of the adjacent chamber, this circulation being effected normally through a passage made in the upper part of the transverse separation wall between the partitions of adjacent chambers, each partition comprising, in its upper part, a plurality of openings. This device consists of a flexible closing means (22) which is rectangular, essentially impermeable to air and supported on each of the two opposite long sides by a rigid profile (21, 21'), these two profiles being connected at their end parts by two connecting rods (19, 19'), (25-25') articulated on the one hand on each profile (21, 21') and on the other hand at their junction point (18, 24), the first articulated junction (18) being arranged on a main profile (12) which forms a support, the second articulated junction being arranged on a traction arm (14) which is movable translationally along the main profile (12). <IMAGE></p> |
