Abstract: A method for producing a weakening line in a surface of a component. The method comprises a guiding step and a skipping step. In the guiding step, a removal apparatus for removing a material of the surface is guided over a plurality of segments of a predefined line-shaped contour by means of an activated laser beam in order to produce a desired wall thickness for at least one of the segments so as to produce the weakening line. In the skipping step, the segment is skipped if the segment has the desired wall thickness.

Abstract: A method for producing a predetermined breaking line in a vehicle interior trim part using a scanning laser beam and inspecting the predetermined breaking line. A transmitted part of the laser beam is detected by individual sensors of a sensor matrix at the individual holes of the predetermined breaking line and individual measurement signals are formed. At least some of these individual measurement signals are stored when a total reference signal is reached by a total measurement signal and compared with the individual reference values assigned to the processing locations. The contour and position of the predetermined breaking line produced can be evaluated from the comparison.

Abstract: A universally usable device for producing a predetermined breaking line in an equipment part of a vehicle. The device includes a laser beam generator, a laser scanner and a linear or matrix-shaped first sensor arrangement with first individual sensors of an identical first sensitivity and at least one identical linear or matrix-shaped second sensor arrangement of second individual sensor, which is arranged with an offset to the first sensor arrangement of first individual sensors, and the second individual sensors have an identical second sensitivity which differs from the first sensitivity.

Abstract: A method and device for producing a predetermined breaking line in a vehicle interior trim part with a scanning laser beam. An actual position of the vehicle interior trim part held in a working plane relative to a laser scanning device is detected by a camera and the actual position of the predetermined breaking line is derived. A stored desired position for a scan figure corresponding to the predetermined breaking line is corrected to an actual position, whereby the predetermined breaking line is produced at a predetermined position on the vehicle interior trim part during scanning of the scan figure. A positional shift of the scan figure becomes possible because a sensor matrix with an upstream diffuser is used, which can detect transmitted components of the laser beam independently of the position of the laser beam along the scan figure.

Abstract: A method for producing at least one patterned design having a plurality of pattern elements via a laser in a component that is at least partially transparent and is coated on a first surface. The component is coated on a first surface with at least one layer. The coated first surface of the component is surveyed with first co-ordinated. At least one patterned design is created with second coordinates. The second coordinates of the at least one patterned design are transformed into third coordinates. The coated first surface is irradiated with laser radiation via control coordinates. The laser radiation is measured on a second surface and the laser radiation received is compared via the sensor system with a reference value. The laser radiation is switched off when the reference value is reached.
