This small range of tolerance is a very important precondition to get good results with REVERSE – COATING.
Additionally the GRINDINGMACHINE offers a rough surface. This improves the adhesion of the glue
to fix the uppers on the sole very much.
There are two types of GRINDINGMACHINES:
The CYLINDERGRINDER should be used for calibration and grinding only.
The WIDEBELTGRINDER could be used for calibration, grinding and fine sanding.
All machines have to pass our FAT (FatoryAcceptanceTest) and will be checked by our technicians according our QC STANDARDS before shipment.
