  • Patent number: 5614115
    Abstract: A laser cutter for cutting textile or leather clothing material adhered on a stiff tacky backing sheet includes a laser which produces a laser beam, a guide head for reflecting and focusing the laser beam onto the sheet-backed clothing material, and an optical sensor mounted on the guide head for recognizing the shape or a pattern marked on the material. The material is supported by an idler roller. Under the control of a computer, a pair of bi-directionally driven pinch rollers move the material back and forth across the idler roller in synchronism with movement of the guide head transversely across the material. The computer alternately activates and controls the optical sensor or the laser. In an optical scanning mode, under control of the computer, the material is scanned to create in the computer memory a model of the desired pattern to be cut in the clothing material, and a desired cutting path matched to the shape of, or pattern on, the clothing material.
