- a support (9) comprising a cup for abutting against an upper face (7) of a grenade body (2), said cup comprising a bottom wall (12) integral with a cylindrical wall (10) having an upper edge (11) for crimping to a priming system (5);
- and
- fastening means for attaching said support to a grenade body.
An attachment device for attaching a priming system (5) to the body (2) of a grenade (1), comprising:
- a support (9) comprising a cup for abutting against an upper face (7) of a grenade body (2), said cup comprising a bottom wall (12) integral with a cylindrical wall (10) having an upper edge (11) for crimping to a priming system (5) and a lower edge for welding to an external wall (15) of a grenade body (2).
A process for attaching a priming system (5) to a grenade (1) body (2), comprising:
- cutting a portion (9) of a metallic tube,
- rounding an end of tube portion (9),
- flaring (16) the rounded end of the tube (9) before or during positioning the tube end on the grenade body (2),
- positioning the tube portion on the external surface of a grenade body (2),
- welding the tube portion (9) to grenade body (2),
- placing a priming system (5) inside the tube portion (9), and
- crimping the tube portion (9) onto a priming system (5).
A process for attaching a priming system (5) to a grenade body (2), comprising:
- cutting a portion (9) of a metallic tube, said tube portion (9) having two ends,
- rounding an end of tube portion (9),
- flaring (16) the rounded end of the tube (9),
- forming a crimping abutment at an opposite end of the tube portion (9),
- placing priming system (5) inside the tube portion (9),
- positioning the tube portion (9) on part of the external surface of a grenade body (2), and
- welding the tube portion (9) to a grenade body (2).
