摘要
For the attachment of a flare composition sleeve in a bore at the tail of a projectile body it was heretofore necessary to maintain very exact fabrication tolerances in order to provide a reliable sealing action against the propellant gases. To avoid this drawback the invention contemplates, in a first method step, pressing the flare composition sleeve, with the aid of a pressing plug or pin, into the bore at the tail or rear portion of the projectile body and, during a second method step, a ring-shaped edge of the flare composition sleeve is enlarged by means of an elastically deformable, such as a plastic or rubber plug until the ring-shaped edge bears against a ring-shaped groove of the bore wall of the projectile body. The flare composition sleeve possesses at the aforementioned end confronting the projectile body a smaller or at most the same wall thickness as at the remaining region.
