Abstract: A laminating device for bonding a protective layer to a substrate, including a driver and a roller head having a shape with a contour to fit a geometric feature of the substrate, is provided. The roller head has a cylindrical symmetry with an axis; the laminating device includes a coupler for mechanically coupling the driver to the roller head. The coupler is parallel to the axis so that the driver provides a rotational motion and a liner displacement to the roller head. The driver also provides a bonding energy to the roller head through the coupler. A roller head for use in a laminating device as above is also provided. A method for bonding a protective layer to a substrate using a laminating device as above is also provided.
