Abstract
Disclosed is a heat-displacing T-die designed so that initial adjustment of a die slit gap can be made easily and accurately in an extensive range, and the controllability of heat-displacing actuators for the die slit gap is improved. A pair of lips are formed as flexible lips. Hand-operated die bolts arranged on one flexible lip, while die bolts adapted to be automatically operated by means of heat-displacing actuators are arranged on the other flexible lip. The arrangement pitch of the hand-operated die bolts is shorter than that of the automatically operated die bolts.
