Method for obtaining a linear detonating shaped cutting charge, charge obtained by said method

A method for obtaining a linear detonating shaped cutting charge, said charge comprising a cylindrical metal sheath with chevron-shaped cross section enclosing an explosive energetic material, wherein it comprises:

• the obtaining of a hollow preformed metal container, having two open distal ends, of cylindrical form with a groove in the form of an inverted V in the longitudinal direction, the cross section of which exhibits a symmetry relative to the median axis of said groove, and which comprises two inner walls delimiting said groove and two outer walls on either side of an apex;
• the obtaining of said container with its internal volume filled with a compression-deformable explosive energetic charge and its distal ends blocked;
• and
• the deformation by compression of a portion, close to said apex, of each of said outer walls of said filled container blocked at its two distal ends, over the entire length of said container, to reduce the filled internal volume of said container with the aim of canceling the voids in said filled internal volume;
• said container, of which a portion of each of said outer walls has thus been made concave, forming said sheath.
