Improvement in self-regeneration ballistic projectile-arrester suitable to fires with small arms or others, in particulars in indoors firing ground

摘要

A self-regenerating ballistic projectilearrester suit­ed for firing with small arms and the like, in particular for use at indoor firing ranges (1), said projectilearrester comprising a granulated material (2) in the shape of a mass so as to ab­sorb the kinetic energy of the projectile, conveyance and trans­sportation means (6) for conveying said material towards the separation zone, means (8) for separating the material from the exploded projectile, and means (9) for carrying the regenera­ted material onto the top of said mass; said projectilearrester being provided with means for supporting the mass of material and for conveying said material towards said transportation means (6) which consists of two belts (4,5) moving in opposite and con­verging directions, said belt (4,5) being at a slope and/or inclinable with respect to the firing plane and being spaced from one another and opposite to one another, and arranged at the bottom of the mass of material (2), with the longitudinal axis in parallel with the firing axis.
