摘要： The present invention generally relates to an apparatus and process for automatically cutting a textile web with reduced wrinkling. The process includes passing the textile web across a first guide roller having a first guide surface directing the textile web to the tension roller, passing the textile web across a let-off roller on the let-off roller surface to compensate for web tension fluctuations as the web textile is passed, moving the textile web from the let-off roller surface in tension around a portion of the tension roller and in contact with the exterior surface of the tension roller, passing the textile web across a conveyor guide surface directing the textile web from the tension roller to an automatic laser cutting apparatus, and cutting the textile web in a predetermined pattern in an automatic laser cutting apparatus comprising a cutting table, a movable laser cutting tool, and a vacuum system, wherein the cutting table comprises a perforated conveyor belt having a conveyor guide surface for directing the textile web from the tension roller and wherein the textile web is held by suction to the conveyor by the vacuum system. The angle formed from the let-off roller surface normal to the ground and the textile web from the let-off roller to the tension roller is from about 2 to 25 degrees. The tension roller holds the textile web in 0.2 to 0.6 pounds per linear inch. The apparatus for automatically cutting a textile web with reduced wrinkling is also disclosed.
