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.

Claims11

Dependent claims

An apparatus for mixing propellant powder rods comprising:

a support frame,
a pair of deflecting drums mounted to said support frame, with said deflecting drums being disposed along parallel axes and being laterally spaced from each other,
a flexible band supportingly draped between said deflecting drums and so that the flexible band is suspended freely and forms a downwardly hanging unsupported loop therebetween,
a plurality of transverse studs mounted on the side of said band facing the interior of said loop,
lateral limiting means mounted to said support frame on each side of the portion of said band extending between said deflecting drums, and
drive means for moving said band back and forth between said deflecting drums,
whereby said band and said limiting means are adapted to support the powder rods so that the powder rods are supported upon the loop of said band and with their longitudinal length being transverse to the direction of movement of said band between said deflecting drums and whereby said transverse studs engage the powder rods and enhance the mixing thereof.
