Tunnel 320

Among the machines proposed on this site we have also included two wood impregnating automatic machine for wooden profiles used in yard construction: the Perlina model (small and compact https://www.woodfloormachinery.com/en/timber-profile-stain-coater-equipment) and the large Tunnel320 fully automatic and with great industrial performance for the pre-finishing colored water based stains treatment of laminated wood profiles, such as beams, laminated and solid fir wood as well.

Tunnel 320 is also a versatile machine capable of applying waxes and solvent-based products (thanks to teflon base treatment of the chassis and mostly important components, and the bottom of the machine completly made in Stainless steel inox) such as dyes and solvent-based products for the treatment of solid wood in spruce and fir douglas timber. It is possible to work matchboards and cladding or fencing wooden elements and apply a coat on 4 sides at the same time in a single quick pass.

Thanks to a clever indirect impregnation system, it is possible to apply the product directly on the wood both in flow coating, or with an indirect roller system that recalls the precision pre-finishing systems for oiling oak wooden flooring.

These machines are aligned with the Paoloni Floor finishing system project, with a spin-off that could be called “Timber Wood Finishing System” .... a general concept linked to the treatment of construction timber.

The 5 motorized finishing brushes are adjustable at will, and are connected to electronic inverters that change both the direction of rotation and their speed to differentiate the color finish of the wood depending on how much pigment you want to leave on it (greater or less), which depends not only on the fluidity or viscosity of the product to be applied (waxes, impregnating agents for wood, solvent-based oils, etc.) but also on the impact pressure of the soft PPL brushes, resistant to solvents and consumption (our brushes, if cleaned correctly, last years!), and their spinning speed of course.

The easy disassembly of the brushes and the system connected to the powerful airless pump allows easy cleaning of the machine at the end of the job and a color change in use inside the machine in no more than 20 minutes.
