    Abstract: Method of and apparatus for fabricating spiral wrapped cartridge cases or the like, in which an expandable bladder positioned within the interior of the cartridge case is initially expanded by application of hydraulic fluid at relatively low hydraulic pressure levels and at relatively high flow rates until the bladder substantially fills the cartridge case and then is pressurized at relatively high hydraulic pressure levels to form the cartridge case within a die cavity. Hydraulic pressure is applied to the bladder by a hydraulic pressure generator which is powered solely by the closure of the platens of a conventional industrial press between which the die and the pressure generator are mounted. The pressure generator shifts automatically from its low pressure to its high pressure mode of operation as the press platens close.

    Abstract: A small percussion cap making tool consisting of a Cutter and a Cutting Block. The Cutter is multi-toothed with an internal forming cone, a shoulder to release the finished caps and a cap exit passage. The Cutting Block has a guide for the Cutter, a material feeding slot and a centered mandrel that works in conjunction with the Cutter's forming cone to form the percussion caps. The percussion cap material is placed in the feeding slot and the Cutter is driven downward. On the downward stroke the material is wrinkled, cut, folded and formed into a percussion cap. Extraction of the Cutter from the Cutting Block pulls the cap free of the mandrel so it can be retrieved from the cap exit passage in the Cutter. The percussion cap may then be charged with a priming mixture and used.

    Abstract translation: 一个由切割机和切割块组成的小型打击乐帽制作工具。 切割机是多齿的，带有内部成形锥体，肩部以释放完成的盖子和盖子出口通道。 切割块具有切割机的引导件，材料进料槽和与切割机的成形锥体一起工作以形成冲击盖的中心心轴。 打击乐帽材料放置在喂料槽中，刀具被向下驱动。 在向下冲程中，材料起皱，切割，折叠并形成打击乐帽。 从切割块中提取切割器可以将盖子从芯轴上拉出，以便可以从切割器中的盖出口通道中取出。 然后可以用起动混合物装入打击乐帽并使用。
