本発明は断面円形の硬鋼線材により断面凹凸状のタイヤ
用ヒートワイヤを製造する方法に関するものてある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a tire heat wire having an uneven cross section using a hard steel wire rod having a circular cross section.
従来自動車用空気入りタイヤに用いられるヒートワイヤ

欠点があつた。本発明は上記欠点を除去するものであり
以下その実施例を図面により説明する。Furthermore, as shown in FIG. 1, it is known that a steel strip 3 is shaped to have an uneven cross-section, wound in multiple layers in the circumferential direction, and the ends of which are spot welded. However, in the former case, the wires become dispersed and disordered during vulcanization when bonded to the tire, resulting in a decrease in strength, so the design must take into account a safety factor of m times the required stress, which has the disadvantage of being wasteful. . Moreover, since the latter is made of steel strip, its high tensile strength is low, and it has the disadvantage that its performance is insufficient for reinforcing tires of buses, trucks, etc. The present invention eliminates the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.

As shown in Figure A, a stopper 10 is wrapped around the entire circumference of the wound shaped body 9 to secure it so that it does not fall apart, or as shown in Figure 3, a plurality of shaped bodies 9 are arranged and their inner and outer peripheries are fixed. A heat wire is constructed by fixing the wires with stoppers 11 and 12 so as not to disintegrate. Note that fixing of the orthopedic body may be achieved by using an adhesive or by covering the periphery with rubber instead of using a stopper.
