Abstract
PURPOSE: To effect normal filtering by removing the strain in a punching metal which forms the filter sheet surface and by preventing the production of clearance between the filter sheets.
CONSTITUTION: Soft material is used for an outer ring 1 which receives heat treatment previously, in comparison with a punching metal 3 and a seal pin 8 is inserted to a raw liquid passing hole 4 installed in the outer ring 1. Then, pressure is charged from the inside of a filter sheet A and expansion is made till the outer ring 1 produces plastic deformation so that the strain for the punching metal 3 is removed and that integral deformation of the filter sheet A consisting in the inner and outer ring; 1 and 2, and punching metal 3, can be corrected.
