20110073576 | System and method for efficient laser processing of a moving web-based material - Systems and methods are described for efficient laser processing of a moving web-based material. In one embodiment, a moving web is provided at a selected speed. A laser beam is generated having a focal point positioned to provide either a score or cut in the web. The focal point of the laser beam is moved at a speed less than the selected speed for a selected distance thereby producing a discreet score or cut in the web in the machine direction. The focal point is repositioned to form another discreet score or cut once the prior discreet score or cut is formed. The repositioned focal point is moved at a speed less than the selected speed for another selected distance. The step of repositioning is repeated to form a plurality of discreet scores or cuts in the web moving at the selected speed. The laser beam is therefore able to be generated using less power than would be needed to produce the same type of discreet score or cut if the focal point were stationary as the web is moved at the selected speed. | 03-31-2011 |
