Delay initiator for blasting |
abstract |
A novel initiator (blasting cap) for explosives is provided. The initiator, which may be electric or non-electric, comprises a tubular metal shell having within a base charge, a delay train, a priming charge and an ignition means. Interposed between the delay train and the priming charge is an annular collar or ring of resilient material in contact with the inner wall of the metal shell. The construction results in a markedly improved resistance against shock initiation. |
