Device for rotating bands for projectiles

The device is used in connection with rotating bands (2) for projectiles in order to improve their sealing and gliding properties within a gun barrel. To prevent direct contact between the rotating band (2) and the gun barrel, and in order to reduce frictional contact between same, the outer surface...

description	The device is used in connection with rotating bands (2) for projectiles in order to improve their sealing and gliding properties within a gun barrel. To prevent direct contact between the rotating band (2) and the gun barrel, and in order to reduce frictional contact between same, the outer surface (3) of the rotating band (2) is arranged with a layer (4) of a metal or a metal alloy, having a lower melting point than the material used for the rotating band (2). The layer (4), which melts during launch and adheres to the outer surface of the rotating band (2), acting as a lubricating and sealing agent between the rotating band (2) and the internal surface of the gun barrel.
