Abstract
An improved apparatus for removing at least one portion of at least one coating system present in a multi-glazed window including at least two glass panels alternatively separated by at least one interlayer and forming multiple interfaces; the apparatus includes a decoating device including a laser source that generates a laser beam having a specific direction and two motors configured to displace the decoating device along a plane P, defined by a longitudinal axis X and a transversal axis Y, the decoating device further includes an orientation means to control the direction of the laser beam.

An apparatus for removing at least one portion of at least one coating system present in a multi-glazed window comprising at least two glass panels alternatively separated by at least one interlayer and forming multiple interfaces, the apparatus comprising:
- a decoating device comprising a laser source that generates a laser beam having a specific direction, and
- two motors configured to displace the decoating device along a plane (P), defined by a longitudinal axis X and a transversal axis Y;
- wherein the decoating device further comprises an orientation device configured to control and change the specific direction of the laser beam while the decoating device is displaced along the plane (P), and
- wherein the orientation device is configured during acceleration and deceleration of the device to change the specific direction of the laser so that the laser imparts a same energy to each location on the window as when the device is displaced at maximum speed.
An apparatus for removing at least one portion of at least one coating system present in a multi-glazed window comprising at least two glass panels alternatively separated by at least one interlayer and forming multiple interfaces, the apparatus comprising:
- a decoating device comprising a laser source that generates a laser beam having a specific direction;
- two motors configured to displace the decoating device along a plane (P), defined by a longitudinal axis X and a transversal axis Y;
- and
- at least one rigid pushing device having a Youngs modulus greater than 70 GPa, the rigid pushing device configured to stabilize the apparatus on the multi-glazed window,
- wherein the decoating device further comprises an orientation device to control the specific direction of the laser beam,
- wherein the orientation device is configured during acceleration and deceleration of the device to change the specific direction of the laser so that the laser imparts a same energy to each location on the window as when the device is displaced at maximum speed.
