Abstract
The invention relates to a method for coating workpieces (2), which consist at least partly of wood, wood materials or the like, comprising the following steps: providing a workplace (2), which consists at least partly of wood, wood materials or the like, supplying a coating material (12) which is to be applied to a surface (2a) of the workpiece (2), applying energy to a surface (2a) of the workplace in such a way that lignin contained in the material of the workpiece (2) involves adhesive properties, at least at the surface (2a) of the workpiece that is to be coated, and pressing the coating material (2) against a surface (2a) of the workpiece, wherein the coating material (12) is at least partially bonded to the workplace (2) by using the adhesive properties of the lignin.
Claims15
A method for coating workpieces which consist at least partly of wood, wood materials or the like, comprising the steps:
- providing a workpiece which consists at least partly of wood, wood materials or the like,
- supplying a coating material which is to be applied to a surface of the workpiece,
- applying energy to a surface of the workpiece in such a way that lignin contained in the material of the workpiece displays adhesive properties, at least on the surface of the workpiece that is to be coated, and
- pressing the coating material against a surface of the workpiece, wherein the coating material is at least partially bonded to the workpiece by using the adhesive properties of the lignin.
An apparatus for coating workpieces which preferably consist at least partly of wood, wood materials, plastic, aluminum or the like, comprising:
- a supply device for supplying a coating material,
- a pressing device for pressing the coating material onto a surface of a workpiece,
- a conveyor device for bringing about a relative movement between the pressing device and the respective workpiece, and
- at least one energy source for applying energy to an adhesive agent or agent that can be made adhesive that can be provided independently and/or can be part of the coating material and/or of the workpiece, characterized in that
- the at least one energy source is chosen from the group consisting of laser, infrared source, ultrasound source, magnetic field source, microwave source, plasma source and gassing source.
