Abstract: A longitudinal continuous kiln (1) for drying and vulcanizing rubber profiles includes a lower chamber (3), provided with a conveying belt (11), and an upper chamber (2), carrying hot air. A plurality of convectors (8) heated by the hot air of the upper chamber (2) are arranged aligned inside the upper chamber (2), each of the plurality of convectors furnished with a diffusing nozzle (9). A conduit with a plurality of unitary derivations (7) branched from the conduit (6) are connected to each of the plurality of convectors (8). Pressurized hot air, heated in the plurality of convectors, is delivered through the conduit (6) and is directed toward the lower chamber (3) for purposes of drying and vulcanizing rubber profiles (10).
