FIELD: mechanical engineering. SUBSTANCE: drying and heat chambers are made in the form of a single furnace. The furnace is connected to a temperature control chamber by an air duct with a forced air feed device. A tube cross feed mechanism is made discrete. A heat exchanger connected to an air duct is mounted in the temperature control chamber. Carriages are made in a coating plant and have sealing caps from a heat-insulating material mounted for engagement through the outer surface of the tube and its ends. EFFECT: improved structure. 3 cl, 4 dwg
