Abstract
The invention relates to a method of packaging a detonating cord comprising explosive material contained in a sheath, intended to meet safety regulations of air transportation. The detonating cord is wound on a support in such a manner that every portion of the detonating cord in the winding is spaced apart from the nearest portions which are substantially parallel thereto by a distance (a) lying in a range between the distance below which detonation is transmissible from one portion to the nearest portion, and the distance beyond which said containing sheath is no longer destroyed by the detonation of (a) nearest portion.
