SYSTEM UND VERFAHREN ZUM PERFORIEREN VON BEWEGTEM MATERIAL MIT EINEM LASER

摘要

Irregation tubing 12 has a supply tube 16 and an emitter tube 14 with a common wall 17. The laser 2 is used to perforate the wall of the emitter tube 14 and/or the common wall 17 while the tubing 12 is travelling in direction A. The laser beam 6 reflected by a rotating twelve-sided mirror 8 sweeps across the diameter of the lens 10 and thus its focus 18 is held at the same point along the moving tubing. To perforate the wall 17 the lens can be shifted to the position shown in broken lines or a split lens may be used with half at each position.
