Process for introducing a weakening line (2) through material removal in a fibrous coating material (1), in particular natural leather, in which process a pulsed laser beam (31) is guided repeatedly in a linear manner over the rear side (12), wherein only one laser pulse is emitted for each point of impingement (24), this bringing about an introduction of energy which, at the point of impingement (24), leads to the coating material (1) being heated to a temperature above an ablation threshold and which keeps the temperature in regions of the coating material (1) adjoining the point of impingement (24) below a limit temperature.
