Abstract

PURPOSE:To equalize the resin flow ranging the width direction of the sheet like object, by making resin nearly sheet like within the die of an extruder tip, then bending the resin flow arc like, thereafter extruding it again sheet like. CONSTITUTION:After thermoplastic resin softened by heat in an extruder 1 passes through a breaker plate 2, it is extruded once sheet like within the enlarging part 3 of a die. And the clearance is made larger near the both edges of the bending passage 43 at the bending part 4 of the die so as the resin proceeds more easily at the both edges. Further, the length of the passage becomes shorter at the both edges and longer at the middle part by making the protruding part 44 low at its both edges and high at the middle part. Because the resin coming out simultaneously from the extruder 1 proceeds aligning uniformly at its middle part and edge parts in the sheeting part 5 of the die, the resin flow is equalized and extruded as the sheet uniform in the width direction.
