Abstract

A method for non-contact adhesive activation and securement of a decorative skin to a part, including: applying an adhesive to a top surface of the part; applying the decorative skin to the adhesive after it have been applied to the top surface of the part; locating an upper heating element or elements of an upper heating plate or platen adjacent to the top surface of the part; locating a lower heating element or elements of a lower heating plate or platen adjacent to a bottom surface of the part, the bottom surface of the part being opposite to the top surface of the part; activating an adhesive located on the top surface of the part via the upper heating element or elements of the upper heating plate or platen and the lower heating element or elements of the lower heating plate or platen when the upper heating element or elements and the lower heating element or elements are adjacent to the part, wherein the upper heating plate or platen and the lower heating plate or platen do not contact the part and the decorative skin; heating the decorative skin during the activating step without contacting the decorative skin with the upper heating plate or platen and the lower heating plate or platen; moving the upper heating plate or platen and the lower heating plate or platen away from the part after the activating step; and applying pressure to the decorative skin located on the top surface as well as the portion of the bottom surface of the part via an upper plate and a lower plate, wherein portions of the part on the top surface have a curved surface that is covered by the decorative skin, the curved surface being defined by a radius of curvature that is less greater than 0 and less than 25 mm.

Claims (20)

1. A method for non-contact adhesive activation and securement of a decorative skin to a part, comprising:

applying an adhesive to a top surface of the part;

applying the decorative skin to the adhesive after the adhesive has been applied to the top surface of the part, wherein during the applying step the decorative skin is wrapped around an edge of the part such that the decorative skin extends from the top surface to a bottom surface of the part, the bottom surface of the part being opposite to the top surface of the part;

locating an upper heating element or elements of an upper heating plate or platen adjacent to the top surface of the part;

locating a lower heating element or elements of a lower heating plate or platen adjacent to the bottom surface of the part;

activating the adhesive located on the top surface of the part via the upper heating element or elements of the upper heating plate or platen and the lower heating element or elements of the lower heating plate or platen when the upper heating element or elements and the lower heating element or elements are adjacent to the part, wherein the upper heating plate or platen and the lower heating plate or platen do not contact the part and the decorative skin;

heating the decorative skin during the activating step without contacting the decorative skin with either one of the upper heating plate or platen and or the lower heating plate or platen;

moving the upper heating plate or platen and the lower heating plate or platen away from the part after the activating step; and

applying pressure to the decorative skin located on the top surface as well as a portion of the decorative skin located on the bottom surface of the part via an upper plate and a lower plate, wherein at least one portion of the part on the top surface has a curved surface that is covered by the decorative skin, the curved surface being defined by a radius of curvature that is greater than 0 and less than 25 mm.

2. The method as in claim 1 , wherein movement of the upper heating plate or platen and the lower heating plate or platen is performed by an actuator operably coupled to the upper heating plate or platen and the lower heating plate or platen.

3. The method as in claim 2 , wherein the actuator is controlled by a controller.

4. The method as in claim 1 , wherein the upper plate and/or the lower plate have complimentary curved surfaces for applying pressure to the curved surface.

5. The method as in claim 1 , wherein the heating elements of the upper heating plate or platen and the lower heating plate or platen are provided in sections that are controlled by a controller.

6. The method as in claim 1 , wherein the pressure applied to the decorative skin located on the top surface as well as the portion of decorative skin located on the bottom surface is applied via pneumatic or hydraulic cylinders to conjoin the part with the decorative skin.

7. The method as in claim 1 , wherein the pressure is applied via application of a vacuum to the decorative skin and the part.

8. The method as in claim 1 , wherein the heating elements of the upper heating plate or platen and/or the lower heating plate or platen are configured to follow a perimeter of the part.

9. The method as in claim 8 , wherein the heating elements of the upper heating plate or platen and the lower heating plate or platen are provided in sections that are controlled a controller.

10. The method as in claim 1 , wherein the radius of curvature is greater than 0 and less than 20 mm and the decorative skin is a thermoplastic olefin or leather.

11. The method as in claim 10 , wherein the upper plate and/or the lower plate have complimentary curved surfaces for applying pressure to the curved surface.

12. The method as in claim 1 , wherein the decorative skin is selected from the group consisting of: a thermoplastic olefin, leather, vinyl and cloth.
