  • Patent number: 4941244
    Abstract: A method of producing a discarding propelling cage sabot projectile, and to a discarding propelling cage sabot projectile produced according to this method, in which, in a vulcanizing tool including an injection mold, a uniformly thin layer of rubber is applied to the rear gas pressure receiving surface of the sabot so as to secure and seal the individual sabot segments against one another. In such a method, when the liquid sealing material is injected into the injection mold, there exists the danger that, due to the high pressure existing at that time, sealing material may enter, in an uncontrolling manner, into the cylindrical inner annular gap or annulus between the sabot and the projectile body. This may considerably adversely influence the release behavior of the discarding sabot segments and lead to a reduction of hit accuracy.
