An apparatus for coating a workpiece that consists at least in sections of wood, wood-based material, synthetic material or the like. The apparatus can include a pressing device for pressing a coating material onto a surface of the workpiece to be coated, a conveying device for inducing a relative movement between the workpiece and the pressing device, an activation device for activating a joining agent used for joining the coating material to the surface of the workpiece to be coated, and a sensor for detecting an operating variable of the joining agent. The apparatus can include a shielding device for shielding a sensor section of the sensor.

Device and method for coating a workpiece

A printing device can be used to print on a surface of a workpiece made at least partly of wood, a wood material, synthetic material, composite material or the like. The printing device can include an ink supply device holding a printing ink and an ink feed system by means of which the printing ink can be supplied to a print head in order to carry out a printing process The device can also include a flushing device that can flush the ink feed system or the print head with a flushing liquid for a printing ink change.

A transport system () for transporting workpieces () which preferably consist at least in sections of wood, wood-based materials, plastic or the like, comprising at least one circulating transport means (); a guide arrangement () for guiding the at least one circulating transport means (); at least one sensor () for detecting at least one condition variable, in particular the preload force and/or instantaneous load on the at least one circulating transport means () and/or the dynamic behavior of at least one section () of the transport system (); and at least one actuator () for influencing at least one condition variable of the transport system ().

Transport system and transport method

The present invention relates to a method for thermally activating a functional layer of a coating material, preferably an edge material, wherein the method comprises the following steps: providing the coating material; feeding the coating material to a device for thermally activating a functional layer of the coating material; and thermally activating the functional layer of the coating material, wherein the thermal activation of the functional layer of the coating material occurs by microwaves which are generated by at least one semiconductor wave generator. The present invention also relates to a device for thermally activating a functional layer of a coating material.

The invention discloses a process for printing of panel-shaped workpieces, in particular in the region of an edge, in which a section of a panel-shaped workpiece to be printed is subjected first of all to one or a plurality of pre-treatment stages which are selected from a) pre-cleaning, b) degreasing, c) improvement of the adhesion and wetting properties and d) reduction of the electrostatic charge, and in which the pre-treated section to be printed is subsequently printed with a desired pattern, in particular by means of inkjet printing. The invention also provides an apparatus for performing said process.
