Title:
MANUFACTURE OF MULTIPURPOSE EXPANDED METALLIC MATERIAL
Document Type and Number:
Japanese Patent JPS5832529
Kind Code:
A
Abstract:

PURPOSE: To easily obtain a multipurpose expanded metallic material which is flat, free of torsion, and safe by expanding a plate body, having cut streaks, in a wire netting shape, and rolling its connection raised parts.

CONSTITUTION: Cut streaks 6 are formed in a metallic plate body 5 at optional positons and edge parts 7 of the plate body 5 are drawn to right and left to expand the plate body 5, thus forming the whole body in wire netting. Then, a raised part 10 formed at the connection part 9 of each streak 8 is rolled in the direction (a) of a gentle slanting surface by using a rolling roller 11 to flatten the plate body 5 to its original thickness, thus making the whole plate flat. This method facilitates the formation of an expanded metallic material free of strain. This material is usable in safety for many purposes including lath materials, glass reinforcing materials, grating materials for decoration, holding material for flexible bodies, etc.
