Patent ID: 6912784

Claim:
A process for producing a catalyst, comprising the steps of: providing a monolith with a polygonal cross section; tightly enclosing the monolith with a single part jacket made of metal sheet or plate; placing a layer of expanded matting between the jacket and the monolith; bending the jacket with a clamping device into a proper final shape so that edges of the jacket which extend at least essentially in a longitudinal direction of the monolith at least contact each other, the clamping device having at least two profiled pieces that are shaped to conform to a final shape of the jacket and are connected together by a flexible tension element that acts at its circumference on a pressure pad which in turn presses on the jacket, sections of the flexible tension element acting on relatively sharply curved sections of the jacket and the pressure pad acting on and being configured to conform to relatively shallow curved sections of the jacket; and undetachably joining the edges to each other.
