ABSTRACT:
Methods for engraving carpet with beams of radiant energy. A beam of radiant energy, such as a laser beam, is intermittently directed at the surface of carpet to engrave the surface, and, if desired, to cause certain color changes. During the intermittent operation of the beam, the carpet is indexed to allow the beam to engrave designs. Alternatively, the beam may be indexed in relation to stationary carpet by means of lenses or mirrors to engrave designs. The method allows inexpensive and accurate engraving of carpet surfaces by which intricate designs may be formed on those surfaces in a minimum amount of time.
