Two and three-roll calender for high-precision films
For the production of films with extremely low wall thickness tolerances. The gaps between the rolls can be measured or controlled with lowest tolerances and high measuring accuracy.
Laminating calender
COLLIN calenders are used for refining films and sheets by laminating or contact laminating. Complete lines can be designed for: take-off – pre-treatment – pre-heating – calendering – refining – laminating – cooling – cutting – winding
Refining calender
The smoothing calender is used for smoothing thick-walled films or sheets or for embossing, coating and laminating. A swivelling and height-adjustable group of three rolls allows the adaptation to all common processing technologies. Heating is realised either by hot water or oil. Moreover, there is an electric roll heating of up to 450°C.
