A device for heat treatment, especially vaporizer has folds suspended

摘要

Its design and mode of operation is described as follows: The web (10) travels, via a feed roll (11), into the treatment chamber (20) from below. Downstream of the feed roll (11) the web (10) is guided between in each case two support bars (16) which are fastened on circulating chains (15) which are tensioned here. Web festoons are formed which are carried along by the support bars (16) and are transported by means of the chains (15), which are now hanging down, to a festoon guide (17). By means of this device, any slipping of the web (10) during its feed to the support bars (16) of the chains (15) circulating in the treatment chamber (20) is avoided and reliable festoon formation is made possible.
