ABSTRACT:
The characteristic feature of the herein disclosed method resides in that it involves a zone control over temperature and humidity of articles being treated within the space of a tunnel chamber, the articles being blown with an air agent having a temperature of 40.degree.-100.degree. C. prior to the step of temperature increase whereas in the zone of said temperature increase the articles are treated with a steam-air mixture for a period of 1-6 hours, the temperatures and humidity of the mixture being gradually increased to their permissible values corresponding to the given type of articles being treated; in so doing the articles in the isothermal curing zone are affected for a period of 2-6 hours with a heat-carrying agent having a temperature of 60.degree.-95.degree. C. and a relative humidity close to 100% while in the cooling zone the articles are blown with a cooling agent having a relative humidity of 35-90% for a period of 0.3-1.5 hours. The characteristic feature of the apparatus for realizing the method of this invention consists in that the apparatus includes a chamber for pre-drying of articles, said chamber being provided with air ducts and communicated by means of one of the latter air ducts with an air screen manifold located at the inlet to the tunnel chamber.
