Zusammenfassung: | Flexible hose. The urethane resin coated steel wires 3 are spiral wound in a predetermined pitch. The thin film urethane resin tape materials 5a are spirally wound onto the outer peripheral surfaces of the coated steel wires 3. A tube wall 5 is formed by melting or adhering the overlapping surfaces of the tape materials 5. These coated steel wires 3 and tube wall 5 are adhered through a urethane adhesive 6. A narrow urethane resin tape 4a having a higher hardness than the tape material 5a is spiral wound on the outer surface portion of the tube wall 5 covering the outer peripheral surface of the coated steel wire 3 to doubly cover the coated steel wire 3. The narrow tape 4a is integrally fused to the tube wall 5 or integrally adhered to it through the urethane adhesive 6. (Machine-translation by Google Translate, not legally binding) |
