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.

A method and device for producing a tear line on a planar workpiece by material removal by means of a pulsed laser, wherein machining cycles are preceded by a method step for generating and storing a reference signal curve which is formed by reference signals, causing the pulse amplitude of the laser pulses, via removal locations along the contour of the tear line. The achievement of a respective predetermined percentage of the reference signal or of an absolute distance from the reference signal by a measurement signal is used as the space-resolved deactivation criterion for each removal location, which measurement signal is obtained from a transmitted part of the pulse amplitude at the respective removal location.

Method for the linear structuring of a coated substrate for producing thin-film solar cell modules in which tracks are introduced in an upper structure plane so as to be adapted to the path of existing tracks in a lower structure plane in that a structuring tool is controlled in y direction by means of a control quantity which is derived from image recordings of the existing tracks, and the substrate is moved back and forth under the structuring tool. The image recordings for acquiring existing tracks are carried out only during the forward passes. The generation of tracks takes place during the forward passes and backward passes.

An interior lining component of an automotive vehicle and method of making same having a support layer and a decorative layer. The decorative layer is joined, either indirectly via an intermediate layer or directly, to the support layer. A series of alternating slits and bridging elements are formed in the support layer along a desired predefined tear seam line. Blind holes of a predefined residual wall thickness and/or microperforation holes extend into the decorative layer along the predefined tear seam line in the region of the bridging elements and in the region of the slits so that the spacing between the holes in the slit regions is narrower than the spacing in the bridging element regions.
