Device and method for coating workpieces

A method of coating first and a second workpiece by a coating device comprising the steps of:

• causing a relative motion between a pressing device and first and second workpiece by a conveyor of the coating device;
• providing multiple different coating materials in a feeding device of the coating device, which materials are applied to the workpiece or workpieces;
• providing a first joining device of the coating device for activating an adhesive on a first coating material fed by the feeding device;
• providing a second joining device of the coating device for applying an adhesive agent on a surface to be coated of the workpieces fed by the feeding device;
• wherein said first and/or second joining devices further comprise an energy source selected from the group consisting of a laser, an infrared source, an ultrasound source, a magnetic field source, a microwave source, a plasma source, and a gassing source,
• choosing between activation of the first coating material by the first joining device and application of the second coating material, wherein the first and second joining devices are both stored in the coating device;
• feeding the first coating material from the coating device to said pressing device;
• activating the adhesive on the first coating material fed by the feeding device from the first joining device and applying the coating material on the first workpiece,
• applying the adhesive agent on a surface to be coated of the second workpiece,
• feeding the second coating material to said pressing device;
• and
• applying the second coating material to the surface of the workpiece being provided with the adhesive agent.
