摘要：
In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.
