To provide a cord reed screen, a manufacturing method of a member for a tire, and a recycling method of cut pieces of member for a tire allow the member for the tire to be cut wastelessly.SOLUTION: In a cord reed screen 1 comprising a plurality of cords arranged in array, detection cords 2 that can be detected by an X-ray are arranged at both ends in a direction in which the cords are arrayed, and a plurality of organic fiber cords 3 are arranged in a portion sandwiched by both ends. A manufacturing method of a member for a tire includes the steps of: covering the cord reed screen with rubber; detecting positions of the detection cords by using an X-ray; and (a) cutting a part between the detection cords arranged at both ends and the organic fiber cords adjacent to the detection cords or (b) cutting an outside of each of the detection cords at both ends. A recycling method of a member for a tire according to the present invention is a method of recycling the member for a tire that has been cut in (a) and includes the steps of: recovering the member for a tire including the detection cords arranged at both ends that has been cut; and separating the detection cords and the rubber from each other.SELECTED DRAWING: Figure 1
【課題】無駄なくタイヤ用部材を裁断することのできる、コード簾、タイヤ用部材の製造方法、及び裁断されたタイヤ用部材の再生方法を提供する。【解決手段】複数コードを並べたコード簾1は、前記コードを並べた方向の両端部にX線で検出可能な検出用コード2を配置し、両端部間に挟まれる部分に複数の有機繊維コード3を配置してなる。タイヤ用部材の製造方法は、前記コード簾をゴム被覆する工程と、X線を用いて検出用コードの位置を検出する工程と、(a)両端部に配置された検出用コードと、検出用コードに隣接する有機繊維コードとの間を裁断する工程、又は、(b)両端部の検出用コードの外側を裁断する工程と、を含む。タイヤ用部材の再生方法は、(a)で裁断されたタイヤ用部材を再生する方法であって、裁断された両端部に配置された検出用コードを含むタイヤ用部材を回収する工程と、検出用コードとゴムとを分離する工程と、を含む。【選択図】図1
