WIPO Patent Application WO/2020/035835
Kind Code:
A3
Abstract:
Present disclosure relates to a method of and a system (100) for online marking on a metallic sheet (1), in a metal rolling process. The method comprises steps of moving, a laser optical arrangement over the metallic sheet (1), by a retraction mechanism (5). The laser optical arrangement is housed in an enclosure (3). Further, a sensor(4) is configured to identify a cobbled portion on the metallic sheet (1), before commencing with the online marking. The cobbled portion is identified during at least one of initiation of the online marking, and during course of the online marking of the metallic sheet (1). Upon identification of the cobbled portion on the metallic sheet (1), the enclosure (3) is retracted from the metallic sheet (1), while a rolling mechanism associated with the metallic sheet (1) is halted or terminated. Once the cobbled portion of the metallic sheet (1) is rectified, the enclosure (3) is moved to the marking region.
