Procedure and device for cutting articles by laser, particularly a sanitary products and components with a laser spot diameter between 0.1 and 0.3 mm.

摘要

A method of subjecting some items (A) to a treatment of laser cutting along a path predetermined in particular about items selected from sanitary products and components of said products (A), the laser treatment involves the steps of applying to said articles a laser spot and producing a relative movement (3, 9) of scanning between said laser spot and said articles (a) along said predetermined path, the method is characterized by: in which - said laser spot has a diameter of between 100 .mu.m and 300 .mu.m and 2000 .mu.m, - said laser spot has a wavelength between 9.6 microns and 11.0 microns, and - the method comprises the step of Regular together in real time during scanning, the power of said laser spot, the instantaneous relative speed of said laser spot with respect to the article (a) treated and diameter urges ntáneo of the laser spot treatment so that the following relation is met: (See list) - P is the power of said laser spot, - V is the instantaneous relative speed of said laser spot with respect to the treated article, - D it is the instantaneous diameter of the laser spot, and - K is a threshold value selected from 100 kJ / m 2 and 300 kJ / m 2.
