ROLLER COATING

Using the roller method, all types of lacquer can be applied on two-dimensional work-pieces as long as their viscosity is suitable. The thickness of the lacquer film to be applied can be determined by means of a finely adjustable doctor roller.
By this method minimal quantities of lacquer up to over 100 g/sqm can be applied without lacquer wastage. With extremely simple machine setting, this technique allows lacquering work to be carried out at high feed speeds and with solvent-free UV lacquering systems.

Direct roller coater

This machine is used for single stain application, reaction primer and also for conventional and UV-sealers and topcoats. The most basic model incorporates a common drive system for throughfeed, application and doctor roller. Modern machines are equipped with up to 3 separate variable speed drive systems, with facility for switching the doctor roller to reverse rotation for extremely fine application of the topcoats (differential roller coater). The rubber coating of the application rollers is adapted to the relevant application technique.
Two head combination coater
Two head combination coater


This machine, in widespread use throughout Italy permits the application of large amounts of base coat with excellent results. The second application roller which works in reverse rotation applies the larger quantity of material on the front edge and flattens the thickly spread film smoothly. Thanks to a special device, the built up of material on the front edge is avoided. When the "reverse" unit is switched off, this universal machine can be used to carry out all the application work which is possible on the differential roller coater.

The coating can be only slightly thicker than with the single head roller coater. The rotating speed on the second application roller can be adjusted slightly faster or more slowly than the first application roller to achieve a flattening effect for a higher quality finish.
Reverse filling machine

Reverse filling machine


This machine is for filling of raw particle boards, MDF or other panel using water-based or UV-curable fillers. After the roll-coating process, a chromium-plated steel roller rotating in reverse direction presses the filler into the pores of the substrate, creating a smooth effect at the same time.
Combined roll staining machine
Combined roll staining machine


This technique is used for applying stains onto veneered surfaces. This machine operates according to the following principle: - the surface of the workpiece is cleaned properly by a special brush, removing any adhering sanding dust (wich is an essential precondition to perfect staining), - the stain is applied by a rubber roller, whose surface is adapted to the type of stain used (for example, sponge roller or soft rubber roller), - one or more brushes ensure an even wiping effect for optimum penetration of the stain into the pores of the wood and removing the surplus stain from the surface.
