Krautzberger Spray Technology for Edge Banding Machines

A special development from Krautzberger for edge banding machines.

The Krautzberger spray technology is utilized for two areas involving the processing of workpieces in the furniture industry.

The Mikro 3 featuring a special nozzle coordinated with the respective coating material sprays the separating agent onto the pressing rollers. This prevents the adhesion of the glue to the pressing rollers. During the next production process steps, the separating agent is also picked up by the sliding blocks. As an added benefit, this prevents residual glue from sticking to the pressing rollers and the sliding blocks. Time-consuming cleaning is therefore no longer necessary.

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.

The Mikro 3 with fine jet extension precisely applies a very thin layer of the separating agent onto the workpiece and thereby minimizes any subsequent touch-up work. The adhesion of the edge clue and dirt accumulation as well as any stickiness on the workpiece are thereby prevented. The surfaces are clean and dry to handle and can be prepared for further processing. As a result of the significantly reduced material consumption, it was possible to significantly lower the material costs in customer applications.

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 opening the control, the control piston charged with compressed air first opens the atomiser air valve and with a short delay the fluid nozzle of the spray gun. During the closing the control, first the fluid nozzle is closed and then the air nozzle.

The fluid is supplied via a ring line with membrane pumps or for small quantities via a pressurised container.

The Mikro 3 can easily be retrofitted into existing machines.

Well-known manufacturers in the furniture industry are already working successfully with the Krautzberger spray technology.

Krautzberger GmbH has been offering standardized solutions for surface technology for more than 110 years. The core competency of the company are customer-specific special solutions that are developed in close cooperation with the customer. In 2011, Krautzberger received the Hermes Award, an international technology award. And in 2012, Krautzberger received the "Surface 2012" award in bronze and was the finalist of Hessen's champions in the category Innovation.
