制造旋转对称尤其圆柱形滤网装置的方法
摘要：
本发明涉及一种制造用于处理纤维悬浮液的旋转对称尤其圆柱形滤网装置的方法。在这种滤网装置中，在垂直于异型棒条平放的异型棒条支架(1、1′)内圆周上，安装并固定许多平行于轴线排列的异型棒条。滤网装置的最终形状通过异型棒条支架(1、1′)的变形造成，在变形时需要的弯曲力例如作用在两个或四个处于异型棒条支架(1、1′)外圆周上的位置(8、9)上。
摘要（英）：

Producing a rotationally symmetric, especially cylindrical, screen comprises inserting profile bars into peripheral recesses in a bar holder so that the bars are parallel to one another, forming the holder into a ring with the recesses on the inside by applying bending forces in at least two positions on the outside of the holder so that the recesses are constricted to clamp the profile bars, and joining together the ends of the holder. An independent claim is also included for a screen cage for a pressure sorter for use in the papermaking industry, produced as above.
