Beam guiding bellows for a laser cutting machine and method for producing a jet leading bellows for a laser cutting machine

摘要

Disclosed are a novel jet leading bellows for a laser cutting machine and a method of manufacturing the jet leading bellows for a laser cutting machine that no longer require a workflow for arranging any particular panels, such as reflective panels, thus enabling manufacturing in a shorter time at a lower cost. The jet-guiding bellows is formed by a plurality of superimposed cloth bodies that are integrally folded to alternately form hill portions and valley portions, and is made freely expandable and contractible in the overall length as the angles of the hill portions and valley portions change the inner cloth body disposed innermost is formed of a material suitable for protecting the inner cloth body by absorbing or reflecting the laser light which has been scattered or reversed, or has a protective layer formed on the inner surface thereof is formed of a material suitable for protecting the inner cloth body by absorbing or reflecting the laser light, and the inner cloth body has protruding flaps which automatically alternate in the process of being folded together with the other cloth bodies d to form the hill sections and the valley sections, are formed so that they project further from the vertexes of the valley sections.
