kleidung des Hohlraumes. Die Auskleidung ist gemäß aus Fäden aus Kunststoff- und/oder Naturfasern in

in Frage kommen, hergestellt. Mit einem stoff mittels der Auskleidung 2 abgegrenzt ist. Aus
solchen biegsamen Material wird einerseits genügend den nachfolgenden drei Beispielen gehen mit der
Widerstand der Auskleidung gegenüber dem Preßdruck Erfindung erzielte Erhöhungen der Detonationsgeder
umgebenden Sprengschnur gewährleistet, so daß schwindigkeit hervor,

derersei-£ die Flexibilität der Sprengschnur bewahrt. Beispiel 1clothing of the cavity. According to a further feature of the invention, the lining is spun from threads made of synthetic and / or natural fibers from a plurality of layers that are covered with the waterproof but flexible material, for example from a dense thermoplastic coating 5 to the outside from a thermoplastic synthetic material, in particular being covered . Centrally within the Sprengstoffseelc 3 of their polyolefins, such as high pressure polyethylene and poly 5, the cavity 1 is arranged, which are made against the explosive propylene in question. Is delimited with a substance by means of the lining 2. From such flexible material, the following three examples will on the one hand sufficiently ensure increases in the detonation of the surrounding detonating cord achieved with the resistance of the lining to the pressing pressure, so that speed is evident,
the cavity is not compressed and an- io.
however, the flexibility of the detonating cord is retained. example 1
