    Abstract: A method for the introduction of at least one locally limited weakening into a decorative composite, in particular for use in an automotive vehicle, by way of a plurality of laser beams, is disclosed. The decorative composite includes at least one decorative substrate, at least one decorative material and at least one upholstered layer arranged between the decorative substrate and the decorative material. The weakening is formed after the joining of the decorative composite as a sequence of first blind holes or perforations, which penetrate the decorative substrate completely, and unweakened webs between these blind holes or perforations. At least one second blind hole, which does not penetrate the decorative substrate, is introduced into at least one web. The first blind holes or perforations are formed in at least two operations, wherein in a first operation, a preliminary weakening which does not penetrate the decorative substrate completely is introduced into the decorative substrate and, in at least one further operation, at least one subsequent weakening of the decorative composition is introduced through the region of the preliminary weakening. Each subsequent weakening has a smaller cross-sectional area perpendicular to the depth of the decorative composite than the preliminary weakening. A trim element for an automotive vehicle, including a decorative composite produced according to the method is also disclosed.

    Abstract: An apparatus is disclosed for cutting a workpiece. A laser beam is directed at successive points along a workpiece surface to be cut and a sensor emits a sensing beam directed at the same successive points as the cutting beam. A beam combining device receives both the sensor beam and the cutting beam and causes downstream beam segments to be collinear with each other as they impinge the workpiece surface. The cutting is thereby able to be carried out in a single pass, and is precise, repeatable and independent of cutting depth, angle of cutting, scoring patterns, material inconsistency, material color, and surface grain variability.
