A device for a retreading plant is suggested, wherein tyres prepared for retreading and comprising a carcass or a casing and a tread band applied thereupon will be vulcanized by the aid of heat and pressure. The retreading plant comprises a number of individual vulcanization chambers (13) of the press mold type. The process heat and pressure which is let out at the end of the vulcanization process is led via a conduit (16) into a preheating compartment (12) wherein not yet vulcanized tyres (10) are stored, and thereby a preheating of said tyres (10) is achieved so that the vulcanization process time and hence the energy consumption thereby can be decreased. The conduit (16) comprises fan means (17), distribution nozzles for internal air circulation for the heated process air, and a pressure reducing valve. |
