These COLLIN flat film lines combine smoothing calender and chill roll and are used in the production of thin-walled or thick-walled films.
The 3-roll unit can be used for vertical or horizontal operation – the roll group can be swivelled by 90 degrees. The forces in the smoothing gap can hydraulically or pneumatically be generated. The smoothing roll is suitable for a wide selection of applications such as smoothing, embossing or laminating.
The roll unit is suitable for 2 working positions:
The control panel is mounted at the switch cabinet and includes a 10“touch screen (CMI 10), function keys, a data wheel and an emergency stop button. The control has an interface to the optionally available software Visual FECON.
