摘要： The invention concerns a process to cut, perforate, or inscribe repeating patterns in continuously-moving flat material by locally vaporizing the flat material with at least one controllable laser beam from at least one beam deflection system whereby each laser beam is moved relative to the flat material in two perpendicular directions (x and y) from a fixed point, and a device to implement the procedure. A pattern can be created at any speed that is perfectly aligned in reference to the bent or folded edges by the following steps: Detecting the rate of the flat material, providing bent or folded edges in the moving flat material and detecting its position, controlling the beam deflection system so that it executes the cutting, perforation or writing process depending on a synchronization pulse generated when the bent or folded edges are detected, and the detected rate of the flat material, and monitoring the beam position/beam intensity of each laser beam depending on the detected rate of the flat material and the detected bent or folded edges.

摘要： The present invention relates to the production of a series of holes in a layer of material, in particular to the production of a target rupture line in a first layer of an airbag cover. The radiation of a plasma that forms during the production of each hole is detected from the surface that is being machined. From the signal pattern derived, the time of the beginning of the signal and the time of the appearance of a falling edge that meets a predetermined edge criterion are detected and stored. The point in time at which the falling edge appears is a switching criterion for switching off the laser. The difference between the two points in time stored for each hole constitutes a quality criterion for the respective hole.
