Japanese Patent JP4570168
Kind Code:
B2
Abstract:
A sheet of expanded metal produced by slitting a sheet of metal, and stretching along a stretching direction, which sheet of expanded metal forms a grid of openings having a first repetition length in the stretching direction and a second repetition length in the direction perpendicular to the stretching direction, wherein the first and second repetition lengths are substantially equal. A sheet of expanded metal having a stretching angle larger than 90 degrees. Use of a sheet of expanded metal according to the invention for supporting a bundle of parallel tubes. A method of manufacturing expanded metal from pre-expanded metal, wherein expansion force is applied at a plurality of points perpendicular to the stretching direction, wherein the expansion force is applied using a plurality of force transmitters co-operating with the plurality of points, and wherein the force transmitters are arranged so that they can move towards each other in the second direction while applying extension force.
