METHOD AND APPARATUS FOR MAKING METALLIC STRIPS OR SHEETS, METALLIC SHEETS OR STRIPS Russian patent published in 2000 - IPC

FIELD: rolled stock production. SUBSTANCE: at least two rolling rolls are subjected to surface texturing according to surface pattern including regular determined two-dimension structure in the form of single cells-spots formed by means of electron beam irradiation. Wave length values used for irradiating rolls in lengthwise direction and wave length values used for irradiating rolls in crosswise direction are less than 1,5 mm. In products made according to invention interference wave lengths of structure are so small or so large that they are invisible for human eyes. EFFECT: possibility for preventing occurring of moire patterns on surface of products. 12 cl, 19 dwg, 2 tbl, 4 ex
