Abstract (en)
[origin: EP0402713A2] To increase the strength of a gun barrel (1) in the region of the ignition plane where the orthogonally laid glass-fibre rovings are partially destroyed by the bores (5) for the ignition tubes (10), a corrugated thickening (7) of the gun-barrel reinforcement is provided. In this wall region, the ignition tubes can be fastened (screwed in) sufficiently securely, so that only an elastic gasket (16) has to be provided between the head (17) of the ignition tube (10) and the ignition ring (12), but there is no need for any mechanical fastening. This affords considerable advantages in terms of production. <IMAGE>
