Apparatus for connecting sheet-like textile articles or webs of material. The processing of different materials in apparatuses with heating plates of constant curvature has hitherto, whenever the material to be processed has been changed, required a corresponding exchange of the heating plates in order to ensure the best possible processing of the material as a result of a more or less pronounced curvature of these. The new apparatus of the invention makes this exchange of the heating plates unnecessary by providing a heating plate which is composed of individual hollow-section heating bodies and which is connected to a supporting trestle on which lifting members act in order to adjust the curvature. As a result of this arrangement, the curvature of the heating plate can be adjusted in a reproducible way and thus adapted to the particular requirements, even during operation. |
