| 摘要 |
The invention relates to an apparatus for the heat treatment of a web of textile material (3) comprising a housing (6), means for guiding the web of material (3) in the housing (6), means for blowing heated treatment gas (5) onto the web of material (3), at least part of the treatment gas being supplied as fresh air and exhaust gas being carried away, and a heat wheel (7) for preheating the fresh air by means of the exhaust gas. It is intended to improve the apparatus in such a way as to create lines for indirectly preheating fresh air by means of exhaust air without any significant additional expenditure and without the height of the apparatus being any greater, or significantly greater, than in the case of apparatuses without preheating. This is achieved by the heat wheel (7) being connected directly to warm sides of the ducts (9, 10) for the fresh air and for the exhaust air, the warm sides of the ducts (9, 10) being routed exclusively inside the housing (6). |
