The 3-cylinders puller forms either a mini-calander or a pulling system for blown film.
The rollers are driven by an asynchronnous geared motor and a double teeth belt . The roll gap is effected by an eccentric system. The metallic cylinder 1 is dismountable, it is replaced by a rubber cylinder in the case of use in blown film.
The pulling system can be connected to a blown film die or die flat film
