The material or fragment discharge is controlled by means of a device (4) in connection to the triggering, such as by means of an initiation charge (5), of the main charge (3) in the ammunition unit (1). The liner is devised as being exposable for effect from the explosive charge or charges (6) that are devised as being able to be initiated upon or shortly prior to the triggering of the main charge. The explosive charge achieves, upon initiation a pre-deformation of the liner (4) prior to the liner being affected by the triggering of the main charge for the material or fragment discharge The fragment forms can be rendered more effective in relation to design solution known by prior art by means of the choice explosive charge form and placement.

The invention claimed is: 1. A device in combination with a liner having a shape with a rear convex surface and a front concave surface to control material or fragment discharge in an ammunition unit's direction of flight from a primary or secondary liner in connection with triggering, by initiation of a main charge of the ammunition unit wherein an explosive pre-charge or pre-charges are arranged at the front side of the liner at a periphery of the liner and that the liner is devised as being exposable for effect from the explosive pre-charge or pre-charges that are devised as being able to be initiated upon or shortly prior to the triggering of the main charge and wherein the explosive pre-charge or pre-charges obtain, upon initiation, a pre-deformation of the liner prior to the liner being affected by the triggering of the main charge for material or fragment discharge. 2. A device in accordance with claim 1, wherein the explosive pre-charge or pre-charges are arranged at the periphery of the liner with an intermediary barrier. 3. A device in accordance with claim 2, wherein the barrier is made of lead, approximately 1 mm thick, and neoprene, approximately 4 mm thick. 4. A device in accordance with claim 3, wherein each explosive pre-charge or pre-charges begin from the exterior circumference of the barrier with parallel interior and exterior surfaces and are arranged with an end surface extending perpendicular to the interior and exterior surfaces and the interior and exterior surfaces allow a central aperture that extends cylindrically from the concave surface of liner in the ammunition unit's direction of flight. 5. A device in accordance with claim 3, wherein the divergent material or fragment discharge, resulting from the initiation of the main charge, obtains angles of dispersion between 5.0-34° and velocities within the range of 380-50 m/s. 6. A device in accordance with claim 3, wherein the liner is deformed upon the initiation of the explosive pre-charge or pre-charges in a random manner over given cross sections. 7. A device in accordance with claim 2, wherein each explosive pre-charge or pre-charges begin from the exterior circumference of the barrier with parallel interior and exterior surfaces and are arranged with an end surface extending perpendicular to the interior and exterior surfaces and the interior and exterior surfaces allow a central aperture that extends cylindrically from the concave surface of liner in the ammunition unit's direction of flight. 8. A device in accordance with claim 7, wherein the divergent material or fragment discharge, resulting from the initiation of the main charge, obtains angles of dispersion between 5.0-34° and velocities within the range of 380-650 m/s. 9. A device in accordance with claim 2, wherein divergent material or fragment discharge, resulting from the initiation of the main charge, obtains angles of dispersion between 5.0-34° and velocities within the range of 380-650 m/s. 10. A device in accordance with claim 2, the divergent fragment or material discharge, resulting from main charge initiation, is given small angles of dispersion within the range of 0.4-9.0° and low velocities of about 540-925 m/s. 11. A device in accordance with claim 2, wherein the liner is deformed upon the initiation of the explosive pre-charge or pre-charges in a random manner over given cross sections. 12. A device in accordance with claim 2, wherein concave and convex surfaces of the liner obtain wave forms in given cross sections. 13. A device in accordance with claim 1, wherein each explosive pre-charge is formed with an exterior surface extending lengthwise to the main charge, and an angled surface, at outer parts of the exterior surface facing a concave surface of the liner, that dilates itself outwards from the concave surface, leaving a central aperture in the ammunition unit's direction of flight that dilates outwards like a truncated cone. 14. A device in accordance with claim 1, wherein the divergent fragment or material discharge, resulting from main charge initiation, is given small angles of dispersion within the range of 0.4-9.0° and low velocities of about 540-925 m/s. 15. A device in accordance with claim 1, wherein the liner is deformed upon the initiation of the explosive pre-charge or pre-charges in a random manner over given cross sections. 16. A device in accordance with claim 1, wherein concave and convex surfaces of the liner obtain wave form in given cross sections. 17. A device in accordance with claim 1, wherein the ammunition unit is a missile or a projectile.
