Abstract

PURPOSE: To form the partially flat part along inner and outer surfaces of the bellow tube by a method wherein a part of a corrugated resin belt extruded and molded on the outside of a screw feeding mechanism are crushed intermittently.
CONSTITUTION: A corrugated belt T made from soft synthetic resin 22 wherein a hard synthetic resin filament 21 is buried in an axial direction extruded by an extruder 20 is wound on to a set of molding rolls 3. The belt T advances on the set of molding rolls 3 in a spiral form under the guidance of a push roll 4, is compressed by the push roll 4 to the adjacent belt and the belts in a semimolten state are cemented to each other to form a bellow tube H with a corrugated exterior congruous to the outer shape of the push roll 4. When a flattening roll 5 is brought adequately into contact with the bellow tube H, the semimolten corrugations are crushed and a partially flat bellow tube is obtained.
