Abstract
The invention relates to a method for applying edge strips (edge tape) onto narrow surfaces (narrow sides) of plate-shaped work pieces (material parts) by joining, wherein the edge strip is applied with a glue that can be activated by heat and is heated by plasma radiation. The invention further relates to the materials to which edge strips have been applied obtained in said way and to a device for carrying out said method.
Claims20
A method for attaching an edge band to at least one narrow face of an in particular panellike workpiece by jointing, said method comprising the following steps:
- the edge band is provided on its side to be joined to the workpiece with a heat activatable adhesive layer which is heated by irradiation prior to jointing;
- wherein the heat-activatable adhesive layer is of plasma-activatable form, and wherein the heating of the heat-activatable adhesive layer takes place by means of plasma irradiation, where the plasma irradiation takes place by means of a plasma source having two or more plasma nozzles, where the temperature of the plasma is 200 to 1000° C. and/or where the plasma irradiation acts with an energy of 0.5 to 20 kWh on the plasma-activatable adhesive layer.
An apparatus for attaching an edge band to at least one narrow face of a workpiece by jointing, where the apparatus comprises:
- at least one means for storing and dispensing an edge band,
- at least one energy source for heating an edge band,
- at least one pressing means for pressing an edge band against a narrow face of the workpiece, and
- at least one transport means for moving or transporting the workpiece;
- wherein the energy source is a plasma source, where the plasma source is capable of generating plasma temperatures of 200 to 1000° C. and/or an energy of 0.5 to 20 kWh and wherein the plasma source has two or more nozzles, where the nozzles are displaceable and where the nozzles are positionable and/or positioned between a narrow side of the workpiece and the edge band.
