PURPOSE:To increase the ratio of the actual time for cutting by freshly mounting a band-shaped work on one movable supporting base during laser processing or intermittent transfer of another band-shaped work after the end of the laser processing up to the terminal of the one band-shaped work and repetitively executing such operations. CONSTITUTION:The band-shaped works 2A, 2B on a pair of movable supporting bases 41, 42 are subjected to laser processing of prescribed patterns by a laser beam 21 of a single laser processing head 22 which can be two-dimensionally scanned. The one band-shaped work 24 is intermittently transferred by each scannable range of the laser beam 21 preferentially from the front end to the terminal and is thereby processed. The band-shaped work 2A is freshly mounted on the one movable supporting base 41 during the laser processing or intermittent transfer of the other band-shaped work 2B right after the end of this laser processing. Such operations are repeated. The productivity per time is improved in this way. |
