Abstract

A detonating cord transport package comprising a plurality of sections, with each section comprising:
- a. a detonating cord separator-support member having front and back face surfaces and edge surfaces;
- b. a continuous length of detonating cord disposed for support on said separator-support member and traversing portions of said surfaces such that there are a plurality of crossover locations on said front face surface where a second detonating cord portion crosses over a first detonating cord portion;
- c. severing means interposed between said first and second detonating cord portions at each of said crossover locations;
- and,
- d. retainer means maintaining said severing means in abutting relation with respect to said detonating cord first and second portions and restraining said detonating cord first and second portions against movement away from said front face surface.
