Method for manufacturing engraved rolling roll and apparatus for performing the same

摘要

Disclosed is an apparatus for manufacturing an engraved rolling roll (102) comprising a laser beam generator (110) for generating a laser beam, a modulator (120) for intermitting the laser beam, a beam expander (130) for expanding the diameter of the laser beam, a laser beam projecting portion (140) for projecting the laser beam to the surface of a roll (102) to form a pattern thereon, and a roll driving portion (150) for rotating the roll. The pattern projecting process is controlled by a control portion (160) and the pattern projecting process is displayed in real time. Also disclosed is a method for manufacturing an engraved rolling roll comprising the steps of forming a resin layer on the surface of a roll, forming a pattern by projecting the laser beam to the resin layer and engraving the pattern on the surface of the roll. The pattern is formed by projecting of the laser beam to the resin layer and the surface of the roll is engraved to a predetermined depth by a corrosive solution. Various materials of steel sheet, wood, paper, rubber, etc. can be utilized. A continuous and beautiful pattern can be obtained and the work can be carried out in a bright room. The generation of waste water can be restrained.
