Abstract

PURPOSE:To form thicker sections that have a required length, by providing rollers in one section of a driving belt which is used to pull out a resin tube extruded from a extruder, and by periodically changing resin pull-out speed. CONSTITUTION:A pulling out device 5 is constructed in such a way that a pair of driving belts 51 hold a resin tube A in between and pull it out. A chain of rollers 52 that rotate themselves freely, are installed in one section of the each belt 51. At that section, the belt 51 slips on the resin tube A so that resin tube pulling-out speed is reduced; thus increasing the wall thickness of the resin tube A that is extruded from a metallic nozzle 2.
