    摘要： A method to produce plastic tube. The material of the plastic tube is fed around a core having a same diameter as the inside diameter of the tube. The material is fed as an uninterrupted material flow which, after having settled upon the core, goes forward following essentially the helical line in the side direction of the core inside a mold mounted on the core. The plastic tube is formed of the material ribbons and melted plastic material fed to the spaces between the ribbons. The round and rising sheet at the end of the mold directs the material flow to the side direction of the core and the head of the plastic tube gets welded and fixed to the starting tube that is used to draw the tube as the production process advances in the side direction of the core.
