Abstract

PURPOSE: To obtain resin tube having a large diameter readily by extruding the resin from a T die rotating along the inner surface of a tubular drum, obtaining a spiral winding of a sheet, compressing the sheet by rolls, and fixing the edge parts of the sheet to each other.
CONSTITUTION: The T die 3 is connected to a pushing machine 1 via a rotary joint 2. A gear 4 is coupled and fixed to the T die 3. A plurality of rolls 7 are provided to the gear. A tubular cooling drum 6 is provided along the discharge port of the T die 3. When the T die 3 rotates along the inner surface of the cooling drum 6 with the resin sheet being extruded continuously, the sheet is wound in the spiral shape, and the edges of the already extruded sheet are overlapped to each other. The sheet is compressed by the compressing rolls 7 by the cooling drum 6, and the resin tube can be obtained.
