Abstract

A storage arrangement for a strip charge includes a spool having a central aperture into which is placed an end of the strip charge, and a channel extending from the central aperture out to a peripheral wall around which the strip charge is wound. The channel includes a slightly curving portion so as not to unduly bend the strip charge. The spool is removably attached to a base plate that maintains the strip charge in place prior to use.

Claims

1. A strip charge storage arrangement comprising:

a generally cylindrical spool having a top surface, a bottom surface and a peripheral wall;

an aperture in said spool extending from said top surface to said bottom surface; and

an open channel extending from said aperture to said peripheral wall, said open channel having a slightly curved portion.

2. The strip charge storage arrangement according to claim 1 wherein said aperture is centrally located in a plane of said top surface extending to said bottom surface.

3. The strip charge storage arrangement according to claim 1 further comprising a base plate removably attached to said spool.

4. The strip charge storage arrangement according to claim 3 further comprising a plurality of pegs extending from a surface thereof of said base plate in a pattern;

and

a plurality of cylindrical openings positioned in an undersurface of said spool to align for placement on said pegs.

5. A strip charge storage arrangement according to claim 1 further comprising a shrink wrap packaging encasing said storage arrangement

6. A strip charge storage arrangement according to claim 1 wherein said spool is made of a rigid foam material.

7. A strip charge system comprising:

a generally cylindrical spool having a top surface, a bottom surface and a peripheral wall;

an aperture in said spool extending from said top surface to said bottom surface;

an open channel extending from said aperture to said peripheral wall, said open channel having a slightly curved portion; and

a strip charge positioned on said spool and extending from said aperture, along said channel, around said curved portion and wrapped around said peripheral wall of said spool.

8. The strip charge system according to claim 7 further comprising an initiator assembly connected to an end of said strip charge within said aperture.

9. The strip charge system according to claim 7 further comprising means to prevent unraveling of said strip charge when wound on said spool.

10. The strip charge system according to claim 9 wherein said means to prevent unraveling is a piece of tape connecting the end of said strip charge to an exposed portion of said strip charge.

11. The strip charge system according to claim 10 further comprising a shrink wrap packaging encasing said strip charge system.

12. The strip charge system according to claim 10 wherein said spool is made of a rigid foam material.
