A flange plate for a manifold of an exhaust-gas system for internal combustion engines, which flange plate can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, and the flange plate can be applied to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, and the flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer. Here, the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, the wall parts having a width b, measured in a direction parallel to the mounting layer, and having a height h, measured in a direction at a right angle to the mounting layer, where h&#x3e;b, wherein the different wall parts delimit a plurality of cavities which are open towards the mounting layer or towards the holding layer or, together with the mounting layer and the holding layer, delimit an open-ended channel.

A method and a device for making catalyst containers preparing, on a single semi-automatic production line, a station ( ), at least a monolith enclosing the monolith with an insulating mat and bonding the insulating mat on the monolith; then slipping and automatically positioning the assembly obtained, in a precut tube, into a mounting and positioning assembly ( ); etching the tube in an etching station ( ); then transferring it into specific elements ( ) for retaining, clamping and driving it in rotation; inserting an insulating cone at stations ( ) dispensing and installing insulation cones; heating simultaneously the ends of the precut tube at a heating installation ( ) maintaining the temperature at the ends to be deformed; deforming the ends, after a predetermined temperature is reached using a device with deforming rollers ( ), while maintaining the forming temperature; extracting and evacuating the resulting container after the floturning and spinning process, towards a continuous cooling device ( ), the box being delivered, at the outlet of the cooling device ( ) into collecting elements ( ) before being stored, conditioned or subsequently assembled.
