摘要

Laser operated cutting and engraving device for materials for electronic control embroidery automatic machines, and/or plotters or rollers, adapted to perform cuts and engravings on pre-established positions and with pre-established forms and sizes on to the materials to embroider. Device comprising the combination of at least a first optical lens (26), operated by a galvanometric motor and provided for the accurate and instantaneous adjustment of the laser beam focal lenght, and at least a second optical lens (27), operated by a step-by-step motor (31) and provided for the rough adjustment of the laser beam focal lenght, between two pre-established positions (A and B). Device comprising an inclined guide member (41) for sliding alternately in the inclined and vertical direction of a system (43) comprising a laser beam source (24), the two optical lenses (26, 27) and two laser beam deflection mirrors (28, 29), so as to deviate the same on to surfaces as wide as possible of the cutting plane (13) onto which the materials (32) to be worked are arranged. Moreover, it is also described the method to embroider materials utilized in this device.
