Through feed ironing and/or embossing machines

Unipress Vario

Through-feed press to iron in intermediate and final stages

UNIPRESS VARIO, the through-feed ironing and glazing machine newly updated to enhance and optimize the ironing process of the greatest variety of leathers.

The new ironing machine with variable contact angle between operative roller and leather allows to increase or decrease the brilliant effect on the leather during the final stage ironing without modifying the touch.

Differently from the UNIPRESS N, the Vario possesses the following extra features:

  • System for the change of the contact between leather and operative roller
  • Automatic felt tensioning system through electric motors adjustable by touch screen control panel.

Indicative Technical Data

Main Features
  • Double-wall-steel-frame designed to sustain centrally the bearings and their housings of operative rollers and counter-pressure roller to avoid structural flexions even when working at the highest pressures;
  • Operative roller of large diameter with mirror-chromed finish to boost the characteristics of the finishing products applied;
  • Inclined position of the operative roller to grant a longer contact of its surface with the leather that has proved to remarkably effective when ironing in intermediate stage;
  • Possibility to work at “zero” (0) pressure for final ironing by using the sole heat of the chromed cylinder and avoid to crush the grain;
  • Operative roller heating by heat transfer oil with spaced distribution system inside the cylinder for the maximum uniformity of the temperature all along its surface;
  • Special rotating joint made by Bergi and oil recirculation system leak proof guaranteed;
  • Automatic felt centring system with manual tensioning;
  • Double feeding conveyor to avoid pleats;
  • Timer for the automatic starting and switching off of the heating system;
