<p>Heat treatment machine by means of hot air of a row of objects (3) in longitudinal displacement. In the hot air circuit and through an exchanger (14), preheated air is provided through a supply valve (17) and used air is evacuated through an exhaust valve (13). A proportional regulation is established between the supply air and the exhaust air. According to the invention, both valves (17, 13) have a relative position such that they may be mechanically coupled, particularly by means of a rod (18).</p> |
