Abstract
An apparatus for mixing propellant charge powder rods. The apparatus comprises a flexible band (1) which is suspended freely in a loop between two paraxial, radially spaced drums (2,3) and is movable back and forth between the drums (2,3) by drive motors (6,7). The band (1) is finite or endless and movable in reciprocation between two winding drums (4,5) each adapted to be driven in either direction of rotation by the drive motors (6,7). The propellant charge powder rods (30) are placed in the suspended loop of the flexible band (1)--transversely of the longitudinal direction of the band--and are mixed together by moving the band (1) back and forth. The length of the loop is increased and decreased periodically during this process.
