PERFECTIONNEMENTS APPORTES AUX JOINTS METALLIQUES ENROULES EN SPIRALE |
摘要 |
For manufacturing a metallic spirally wound gasket having an outer centring ring it is proposed spirally to coil a corrugated strip of metallic material to form a sealing element of desired diameter and to surround the thus formed sealing element with a centring ring which is or has been formed by spirally coiling a metal strip which is of greater thickness than the sealing element strip and has a corrugated cross-section such that adjacent turns of the spiral fit without clearance one against the other. |
