A method of processing cases of bombshells consists in removal of a capsule, paraffin seals and other foreign matters, separation of the bottom part and a mouth (if any), annealing the cylindrical part of case-pipe, longitudinal cutting the pipe into strip blanks, straightening the blanks and rolling. Rolling is performed in rolls on a rigid profiled plate. In the case the blank is set on the plate so that the thinner blank corresponds to the thinner plate. |
