섬유재의 커버 재료(1), 특히 천연 가죽에 물질의 제거를 통하여 약화선(2)을 도입하는 방법이고, 이 방법은 펄스 레이저 빔(31)이 커버 재료(1)의 배면(12)위에 선 형태로 복수의 횟수로 안내되며, 단지 하나의 레이저 펄스가 각 충돌점(24)에 대하여 방출되며, 상기 레이저 펄스는 에너지 입력을 야기하고, 상기 에너지 입력은 각 충돌점(24)에서 상기 섬유재의 커버 재료(1)를 제거 역치 이상의 온도로 가열하고, 충돌점(24)에 인접한 섬유재 커버 재료(1)의 영역에 한계 온도 이하의 온도를 유지한다.
Introducing a defined line of weakness (2) by removal of material to a fibrous covering material (1), comprises directing a pulsed laser beam (31) to the rear side of covering material having display side (11) and a rear side (12) opposite to it, and linearly guiding; and determining a depth of the resulting score line of impingement of a laser beam along a line in each case by many laser pulses. The linear guiding is a multiple repetition of a scanning, and only one laser pulse is emitted, respectively per point of incidence when guided along the line. Introducing a defined line of weakness (2) by removal of material to a fibrous covering material (1), comprises directing a pulsed laser beam (31) to the rear side of covering material having display side (11) and a rear side (12) opposite to it, and linearly guiding; and determining a depth of the resulting score line of impingement of a laser beam along a line in each case by many laser pulses. The linear guiding is a multiple repetition of a scanning, and only one laser pulse is emitted, respectively per point of incidence when guided along the line, which causes an energy input leading to the respective point of incidence to the heating of the fibrous coating material to a temperature above an ablation threshold and maintains a temperature adjacent to the areas of point of incidence of the fibrous coating material below a limit temperature that would lead to changes in the structure of the fibrous coating material.
