Abstract

Process for the manufacture of a rolling cage for cylindrical rolling bodies, starting from a flat strip that after forming the receiving pockets of the rolling bodies, is bent into a cylindrical shape, characterized in that after punching the bags 2 with contour essentially rectangular, its introduces in a contiguous bags 2 a pinching tool, with two stamping jaws, 4 and is placed under the action of pressure in such a way that the stamping jaws 4 plastically form both sides of the core 6 that separates both bags, 2, in such a way that when forming on the edges of the webs a central guide zone 8 covering almost the entire length of the bags and holding areas 9 on both sides, for the rolling elements 7 material is removed on the delimiting faces 10,11.
