The working process:
The reactive poly-urethane (PUR) glue is melted in a drum melter and automatically being pumped into the roller coater. On the core material, mostly plywood, the PUR hotmelt glue is applied, around 120 gr/m2. By hand the operator puts the oak lamella on top of the glued core.

The roller press now strongly presses both pieces together.

The production process is much faster than using PVA glues in a normal cold press.

The PVA gluing / pressing process takes around 30-40 minutes, our new PUR line can be used in a continued production process. So this is a big advantage!

This way you can avoid the stack press and work continuously and stack the pieces directly onto the pallet. We believe this new technique is essential to those who need to reduce their production time, resulting in a higher output rate. And of course these new PUR machines can also be used for several other purposes, like adding an insulation layer to flooring or making wall panels, like the very popular acoustic wooden slat panels for example.
