Abstract:
1. An apparatus for cutting and/or marking products by light beams, comprising a laser light source located in a fixed position to generate a laser light beam, reflection and focalizing optics including at least one laser light focalizing head to divert and focalize said laser light beam towards a working plane onto said products; said focalizing head being movable in a first direction (X) along a cross-bar, said cross-bar being in turn moveable above the working plane in a second direction (Y) transversal to said first direction (X), wherein the cross-bar engages two parallel guides arranged laterally with respect to said working plane, a single common transmission belt extends along an H path defined by the cross-bar and said two guides and engages said focalizing head and said cross-bar, to control its movement in said direction (Y), and to control the focalizing head movement in said direction (X), and said single transmission belt is driven by four motors, each of the four motors being positioned in correspondence of an end of said parallel guides, said single transmission belt connecting said four motors and being guided by idler wheels of the cross-bar.
