Krautzberger spray technology for edge banding machines

This Krautzberger spray technology is used for two applications when it comes to the processing of workpieces in the furniture industry.

In one application, the Mikro 3 spray gun, equipped with a special nozzle, sprays a separating agent onto the workpiece in order to to prevent the adhesion of the glue to the pressing rollers. In a further production step, the separating agent is also taken up by the sliding blocks. This prevents glue residue from sticking to the pressing rollers and the sliding blocks. Time-consuming cleaning is therefore no longer necessary.

In another application and prior to the edge banding, the workpiece is treated with a special separating agent, which is applied to the top and bottom surfaces of the workpiece to prevent the glue from sticking to it. Here the Mikro 3 with fine jet extension precisely applies a very thin layer of the separating agent onto the workpiece and herewith minimizes any subsequent touch-up work. The adhesion of the glue, dirt accumulation and stickiness of the workpiece are prevented. The surfaces are clean and dry to handle and can be prepared for further processing. As a result, the material consumption can be significantly reduced.

The Mikro 3 spray gun is pneumatically controlled and features an integrated preliminary air control. The control is triggered by a mechanical or electro-mechanical 3/2-way valve. When the control is triggered, a control piston, charged with compressed air, first opens the atomizer air valve and then with a short delay the fluid nozzle of the spray gun. When the operation stops, first the fluid nozzle is closed and then the air nozzle.

The fluid can be supplied either with diaphragm pumps or, for small quantities, via pressure tank. The Mikro 3 can also easily be retrofitted into existing machines. Well-known manufacturers in the furniture industry are already working successfully with this Krautzberger spray technology.
