Title:
PERFORATED METAL SHEET, ITS MANUFACTURE METHOD, SUPPORTER AND PLATE OF CELL USING THE SHEET
Document Type and Number:
WIPO Patent Application WO/1994/006604
Kind Code:
A1
Abstract:
Metal sheet having less residual stress in its interior, a great tensile strength, a small inner resistance, and an excellent capability of supporting substances. In the metal sheet a number of holes (4) are made with punches (2) alternately in two directions and have rupture projections (5) in the punching directions. Such perforated metal sheet (6) can be manufactured preferably by passing metal sheet (3) between a pair of rotating rollers (1) which faces each other, are arranged rotatably in the directions opposite to each other, and have punches (2) on both cylindrical surfaces in such a way as to be interdigitated. The perforated metal sheet is particularly useful for the manufacture of the plates of a cell which support active material. The sheet is also useful for the manufacture of various supporters of substances such as in a preferably catalyst unit which supports a catalyst, and a preferable filtering unit which supports a filtering material.
