摘要：
A producing method of a steel cord play includes first and second topping steps. In the first topping step, a first topping rubber is concentrically attached to a periphery of each steel cords. With this, steel cords having rubber which are pre-coated with the first topping rubber are formed. In the second topping step, a second topping rubber is attached to at least one surface of a steel cord array in which the steel cords having rubber are arranged, thereby forming a sheet-like steel cord ply. The first topping step is carried out immediately before the second topping step.
