    • PURPOSE:To prevent the generation of zigzag and disturbance of code pitches by a method wherein only lap sections of tension members are connected by vulcanization through an unvulcanized rubber and a tensile force is applied to both ends of the connection later at the mold pressing. CONSTITUTION:A fancy rubber 3 and a cotton canvas 2 at both ends are peeled off. Only tension members 9 and 9 are lapped one upon another by a proper length in such a manner that an unvulcanized rubber sheet 8 is so arranged between laps to adhere thereto on one side and then, put together by vulcanization under pressure with a small joint press 10. Then, an unvulcanized rubber sheet 11 is arranged on the portions excluding the lap sections of the members 9 and the unvulcanized rubber sheet 8 and the connection of a hand rail 13 is set on a molding die 5 with the cotton canvas 2 and the fancy rubber 3 butting together. When the connection at both ends is molded solidly, a tensile force is applied to the entire hand rail 13 with a tensile force generators 7 each positioned at both ends of the molding die 5. This can eliminate the zigzag of the members 9 and disturbed pitch between the members 9 due to the fluidity of the unvulcanized rubber sheets 8 and 11 near the lap sections.
    • 目的:为了防止产生锯齿形和代码间距的扰乱,其中仅通过未硫化橡胶通过硫化连接拉伸部件的搭接部分,并且在模具压紧时将张力施加到连接的两端。 构成:两端的花式橡胶3和棉帆布2被剥离。 只有张力构件9和9以适当的长度彼此搭接,使得未硫化橡胶片8布置成在一侧之间布置以在其上粘附,然后通过在压力下用小的接头压力 然后,在除了构件9和未硫化橡胶片8的搭接部分之外的部分上布置未硫化橡胶片11,并且将手轨13的连接用棉帆布2和 花式橡胶3对接在一起。 当两端的连接件被牢固地模制时,拉伸力通过每个位于模具5的两端处的拉力产生器7施加到整个手轨13上。这可以消除构件9的锯齿形和干扰的间距 由于未被硫化的橡胶片8和11在搭接部分附近的流动性,在构件9之间。
