Abstract
An improved decoating apparatus including a mounting means to be mounted on a multi-glazed window mounted in situ and a laser device to decoat at least partially a coating system present on a surface of the multi-glazed window. The decoating apparatus further includes a closing means at least partially to reduce the maximum decoatable surface to a working surface. Further, an associated decoating method and use of a closing means to decoat is disclosed.
Claims12
1:
- A laser apparatus, inscribed in a parallelepiped rectangle R defined by a longitudinal axis, X, a vertical axis, Y defining a plane P and a lateral axis, Z, comprising:
- a mounting means to mount the laser apparatus on a window, mounted in situ;
- a laser device generating a laser beam to treat a surface of the window;
- an orientation means able to orientate the laser beam defining a maximum decoatable surface on the surface to be treated;
- wherein the laser apparatus comprises a closing means to at least partially reduce a maximum decoatable surface to a working surface.
2 more elements
2:
- The laser apparatus according to claim 1, wherein the laser apparatus is a decoating apparatus and wherein the laser device is designed to decoat at least partially a portion of a coating system present on a surface of the window.
3:
- The laser apparatus according to claim 1, wherein the closing means comprises a fixing means and a mask able to be fixed to the fixing means in front of the laser beam.

7:
- The decoating apparatus according to claim 6 wherein the movable part is irremovable along the longitudinal axis X and along the vertical axis Y.
8:
- A method of treating a surface of a window mounted in situ with a laser apparatus according to claim 1
- wherein the method comprises:
- A. Choosing a working surface of the surface to be treated;
- B. Selecting a closing means corresponding to the working surface;
- and
- C. Treating the working surface.
3 more elements
9:
- A method of at least partially decoating a coating system of a multi-glazed window mounted in situ with a decoating apparatus according to claim 2 mounted on the multi-glazed window;
- wherein the method comprises:
- A. Choosing a working surface of the coating system to be decoated;
- B. Selecting a closing means corresponding to the working surface;
- and
- C. Decoating at least partially the working surface.
3 more elements
10:
- A method according to claim 9, wherein B further comprises:
- B1. selecting a mask corresponding to the working surface;
- and
- B2. of fixing the mask to a fixing means.
