Abstract

PURPOSE: To completely remove condensed matters on a cooling roll without damaging the same by a method wherein a touch roll rotated at the specified conditions is made in contact with the cooling roll for film forming.
CONSTITUTION: A film 4 extruded from an extrusion head 3 in the fused state is coated on a cooling roll 1 rotated in the direction shown by an arrow and then solidified by cooling. A touch roll 2 rotated in the direction shown by another arrow (in the reverse direction to that of the roll 1) with a lower circumferential speed (about 40W80%) than the roll 1 is made in contact with the cooling roll 1 so as to remove condensed matters on the roll 1 by the action of difference in circumferential speeds of the two rolls. The removed matters are exhausted out through a suction nozzle 5. Contact pressure (linear pressure) between the rolls is set at a range of 1W 3kg/cm.
