ABSTRACT OF THE DISCLOSURE A vulcanizing press for vulcanizing flat articles having locking pawls for locking the pressing plates of the press at a certain distance from each other in the closed vulcanizing position of the press. By letting one of the pressing plates be without heating elements and carry an in- flatable member, such as a membrane, inflated by a pressure fluid, which membrane in the closed position of the press is positioned and adapted to supply a uniform pressure substan- tially over the whole flat side of the vulcanizing article positioned between the pressing plates an even surface pres- sure is obtained all over the textile side of the vulcanizing article substantially independent of the thickness of the article and without use of toggle mechanisms or high power hydraulic cylinders. When the inflatable member is placed on the downwardly facing side of the upper pressing plate the articles can be conveyed into the press on a conveyor belt, the path of which is stationary relative to the press frame, but if the inflatable member is placed on the upwardly fac- ing side of a lower pressing plate without heating elements the difference of the temperature between the upwardly turned side of the articles and the downwardly facing side of the upper pressing plate can be increased whereby the last men- tioned article textile side can be made of a less temperature resistant material.
