VORRICHTUNG UND VERFAHREN ZUM SCHNEIDEN UND ENTFERNEN VON GARNEN |
摘要 |
<p>An excimer or ablation laser is used to cut selected, e.g. warp yarns in a fabric, particularly in joining the ends of a papermaking fabric to make the fabric endless. Optical imaging and electronic guidance of the laser projection is used, and the laser beam may be directed down a probe tube (20), which extends into the fabric and is shaped to push aside yarns to enable the laser to be directed to a target yarn. The laser may also be used for welding yarns in a second stage of the fabric joining process.</p> |
