<p>PCT No. PCT/SE86/00362 Sec. 371 Date Apr. 22, 1987 Sec. 102(e) Date Apr. 22, 1987 PCT Filed Aug. 12, 1986 PCT Pub. No. WO87/01901 PCT Pub. Date Mar. 26, 1987.A device is provided for achieving a seal between the edge portions of two metal plates which are used as screens against electromagnetic fields, the device including a metallic sealing strip which is intended to be compressed along these edge portions. The sealing strip (1) comprises a helically wound metal element with a cornered cross section, and the edge portion of one metal plate (6) is intended, by engaging against a support (4), to be pressed against the sealing strip (1) both in the cross-sectional and in the longitudinal direction of the strip, so that the turns of the helically wound metal element are twisted in the longitudinal direction of the strip in relation to their original positions. Parts of the cornered sides of the metal element will thus be pressed against said edge portions, which gives good metallic contact.</p> |
