Polishing machine POLAR

The new UNIGRAIN XT machine has been designed to give our customers an ironing and embossing  machine easy to use, completely equipped, unique in its type of machines, maintenance easy and intuitive thanks to the self-diagnosis system installed on board of each machine .
The press assures an extreme rigidity of the pressure rollers, allowing a perfect uniform embossing of the leathers in their whole width.
Gives the possibility to work also with zero pressure, to perform final processing using only the heat of the roller avoiding that the leather grain crushed.
A new Introduction system, realized by means of two spreading conveyor belts, allows the use of the machine with any type of leathers, eliminating the problems of folds even on big and soft products.

- Automatic “revolving” system for change the rollers with 2 or 3 rollers selectable.
- Heating of the roller by means of thermal oil using independent heating unit placed in a special compartment side of the machine.
- Heat roller with double wall with thermal oil spiral passage to ensure a constant temperature in all parts of the outer cylinder.
- Independent heating unit for each roller.
- Adjustable temperature up to 180 °C.
- Double – spreading conveyor belts, system to hold the leather during the ironing and embossing process.
- Independent handling devices of felt and spreading conveyor belts, controlled by inverter.
