Disclosed are a novel beam guiding bellows for laser cutting machine, and a method of manufacturing the beam guiding bellows for laser cutting machine, which no longer need a process of placing any special plates such as reflective plates, therefore enabling manufacturing in a shorter time at low costs. The beam guiding bellows is configured by a plurality of stacked sheet bodies integrally folded so as to alternately form hill sections and valley sections, and is thereby made freely expandable and retractable in the overall length as angles of the hill sections and valley sections vary, wherein the inner sheet body disposed innermostly is composed of a material capable of protecting the inner sheet body by absorbing or reflecting the laser light having been scattered or reversed, or having, formed on the inner surface thereof, a protective layer composed of a material capable of protecting the inner sheet body by absorbing or reflecting the laser light, and the inner sheet body has protruding flaps which are formed, automatically in the process of folding it together with the other sheet bodies to thereby form the hill sections and the valley sections alternately, so as to project further inwardly from the apexes of the valley sections. |
