A method for controlling the temperature of a plastic foil band subject to UV radiation has an air cooling system above the band conveyor

摘要

The plastic foil (11) is conveyed in a direction (16) by rollers (18) passing beneath multiple jets (13) connected to a box (12) with a fan (22), a radiation unit (14) and a blind unit (15). The cooling air stream also cools the radiation source (20).
