Abstract
PURPOSE:To provide a good appearance resin the tube having thin part and thick part alternatively by extruding a resin tube from an extruder and taking out the resin tube at speed of two stages through an outer diameter regulating device separated in vertical direction for opening and closing, and of which separated surface is inclined to the axis. CONSTITUTION:An outer diameter control device 2 is disposed in adjacent to an extruder's opening 1. The device 2 has hollow cylindrical part and separated into upper and lower semi-cylindrical parts 21, 22 and its separated surface 23 is inclined to the axis of the hollow cylindrical part. Then a resin tube is taken out by a drawing device 6 in such manner that drawing speed is altered at least two stages and it is taken out at high speed and low speed so that resin tube having thin part and thick part alternatively is obtained. As the separated surface of the outer diameter control device 2 is inclined to the axis, contact seam does not leave on the outer surface of the resin tube and in case that troubles such as blockage is ocuured, the trouble can be easily removed by opening the outer diameter control device.
