发明名称 Method and apparatus for laser engraving of smoke-sensitive materials
摘要 A laser apparatus for use in laser cutting of a plurality of sheets of smoke-sensitive, heat-sensitive material in aligned stacked relation, the apparatus including a base member assembly for producing a magnetic field and for supporting the stack with a template formed of a generally rigid, magnetic material, the pull of the magnetic field on the template urging adjacent sheets into intimate surface contact to substantially eliminate voids therebetween during the cutting process. The template is preferably plated or coated with a reflective substance such as chromium, and the magnetic field may be created by an array of permanent magnets on a magnetic sheet.
