发明名称 FLEXIBLE HOSE FOR VACUUM CLEANER AND METHOD FOR MANUFACTURING THE SAME
摘要 PURPOSE: A flexible hose and a method for fabricating the same are provided to prevent a multi-extruding strip from sticking to a wire burying section by changing a sectional shape of a primary extruding strip. CONSTITUTION: A wire(1) is buried by using an extruder(12). At this time, a primary extruding strip(13) having a large size is extruded. Then, a multi-extruding strip(10) is formed in a sizing mold(14). The multi-extruding strip(10) is wound at a predetermined angle by using a bonding device. In this state, a bonding end, which is a terminal end of a semi-circular section formed at both sides of the multi-extruding strip(10), and a bonding part of a wire burying section are bonded to each other by using an adhesive. The semi-circular section is connected to the wire burying section through a connecting section.
