  • Patent number: 5972139
    Abstract: A method is used to produce thermally shrinkable and electromagnetic wave proof tube and the product thereof which is internally or externally covered with a metallic net-like sleeve woven by soft zinc coated copper wires so as to make the electric cords arrangement in the tube neat, signal transmissions in a higher quality, appealing to eyes and durable against abrasion in use. The net-like sleeve can be woven by means of a weaving machine with different number of soft zinc-coated wires, such as 16, 24, 32 and 48 wires to obtain net-like sleeves of various densities and sizes. A so woven net-like sleeve is expandedly supported by a hollow metallic rod into shape and it can be adhered to the outer or inner surface of a thermally shrinkable tube. The metallic net-like sleeve can shrink along with the plastic tube when heated. It not only can neatly bind electric cords in a tube but also makes the tube appealing to eyes, durable against abrasion and anti-electromagnetic wave in practical operation.
