Unit MSP H.B. allows a perfect ironing of any type of collar, thanks to a patented system based on moulds and counter moulds, easy to install and to produce. The cuff is pressed first on one side and then on the other to give a perfectly accurate pressing to the cuff. The machine operates with a double pressing system and a PLC to set the right time and the temperature. A thermostatic system regulates the temperature of the lower pressing plates.
