Spray onto the upper and lower edge area of the workpiece
? Removal of release agent and loose glue residue
? Cooling of the edgeband and glue joint
? Matt radius of the machined edgeband re-matches the surface finish

The Release Agent LP113/03? is sprayed onto the corner area of the glued on longitudinal edge to prevent the adherence of glue emerging in the corner as a result of the cross gluing process. The picture shows a fine nozzle used to spray the release agent LP113/03? onto the trailing edge moving in the running
direction.

This unit is used to spray the cleaning agent LP163/93? on the top and bottom surface of the board edge, as well as the edgeband. The release agent applied at the machine infeed side and the loose glue residue are removed by the application of the cleaning agent and subsequent buffing.
Furthermore, the glue joint and the edge banding are cooled. Heat generation during buffing is considerably reduced by the application of the liquid. Smearing of glue emerging from the joint is avoided. The edge banding radius is wet buffed with the special cleaning agent LP163/93?. As a consequence, heating of the thermoplastic material is notably reduced, and a smearing of the plastic is prevented. Moreover, the radius is polished to match the surface sheen. Glue residue no longer adheres to the buffing wheels.
Result: An absolutely clean board edge!
This result can only be obtained when the buffing wheels is used across its entire width without oscillation. The buffing disc must be used with an inclination in relation to the workpiece of 3?, without oscillation and applying only slight pressure.
Rotational direction should be in synchronous run to reduce heat generation.
Consumption per fine nozzle: under 1 liter for 5000 running meters. The electronically controlled cleaning agent spraying unit only requires a compressed air connection of 3 bar and a 230/24 V socket.

Upstream of the formatting unit, an ultra-thin coat of the release agent LPZ/II? is applied to the top and bottom surface of the workpieces (edge area) by means of our electronically controlled release agent spraying unit. This prevents squeezed out glue from adhering to the workpiece.
An ultra-thin application of our release agent in the edge area (consumption per nozzle under 1 liter per 5000 running meters) guarantees a perfect result.
The electronically controlled release agent spraying unit only requires a 3 bar compressed air connection and a 230/24V outlet.
Our special release agents are adapted to all commercially available glues. In illustration 1 you can see the installation of the spraying unit inside the cladding directly before the formatting unit, with the relevant fixing bracket. Our fine nozzles are not sensitive to dust and can therefore be fitted directly in front of the tooling.
In illustration 2 you can see the installation outside the cladding, prior to formatting, with the appropriate bracket. On the opposite side of the machine the unit is connected to the longitudinal fence with the appropriate bracket. We also have an assortment of special fixings to meet your needs.
For post- or softforming machines our high heat resistant release agent TH97? is used. This special release agent can pass without problem through hot zones without losing its effectiveness.
