The direct use of the pipe previously known by the German from the soft material, for example asbestos fabric, utility model I 927 873, must be kept away. The metallic reinforcement consists of a flange seal for sealing cylinder heads, a profile with an approximately U-shaped profile in internal combustion engines was not possible, because the sheet metal strips, the two mutually parallel externally inwardly drawn welding noses due to the 20 outer snub ends 7, 8, relatively large the edge of the soft material The accumulation of material to form hot ignition encompasses the seal 4 and tends to seal the flange area as well as natural vibrations of the inner enveloping body 9, 1Φ of the cylinder block 2 or head 1 ano area. In addition, the use lies. The / wipe the leg ends 7, 8 have a completely different task, so stretching the soft material sealing edge 5 acts that the use of a similar seal to the 25 as an elastic support body. Between the two external avoidance of continuous oscillation fractures in the case of outer, parallel leg ends 7, 8 and internal combustion engines, for the person skilled in the art there is no conductive, curved connection point 11 of the enveloping basket. Finally, only one of the legs 12, which now run closer to one another, represents a task-solving seal, which is not supported and not on the fen, in that the connection point of the two flange surfaces 9, 10 are in contact. In the case of a swinging angle, a curved section is formed, ie, with a constantly changing distance, which leads to a uniform thermal and mechanical resistance between the two leg ends 7, 8, as well as a niche load-bearing capacity of the enveloping body. the oscillating deformations in particular the
