Abstract
A method for mixing propellant charge powder rods utilizes 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.
Claims10
A method of mixing propellant charge powder rods comprising the steps of placing a plurality of propellant charge powder rods in an upwardly open, freely suspended loop of a flexible band, with the powder rods disposed parallel to the plane of the band and transverse to the lengthwise direction of the band, and periodically moving the band such that the band in the loop is moved back and forth in its lengthwise direction and so as to cause the powder rods to be intensely mixed.
