Patent ID: 7528343

Claim:
A method of subjecting articles chosen between sanitary products and components of said products to laser cutting treatment along a pre-set path, the laser treatment comprising: applying to said articles a laser spot and producing a relative movement of scanning between said laser spot and said articles along said pre-set path, the laser spot having a diameter of between 50 μm and 800 μm, said laser spot having a wavelength between 9.6 μm and 11.0 μm; and regulating in real time during the scanning jointly the power of said laser spot, the instantaneous relative speed of said laser spot with respect to the article treated and the instantaneous diameter of the laser spot so that the following relation is satisfied: P D × V ≥ K where P is the power of said laser spot, V is the instantaneous relative speed of said laser spot with respect to the article treated, D is the instantaneous diameter of the laser spot, and K is a threshold value chosen between 100 kJ/m 2 and 300 kJ/m 2 .
