Abstract (en)
[origin: EP3028783A1] To prevent generation of scratches of straight stocks and improve quality of the straight stocks, and obtain a stable ring shape. Between a pinch roll P and a laying head H, first to third guidance equipments G1, G2, and G3 for guiding straight stocks are disposed, the first guidance equipment G1 on the most upstream side includes a plurality of bend forming roller guides G11 and G12 for giving a curvature enabling bending in a laying head H direction to the above-described straight stocks, the second guidance equipment G2 includes a plurality of directing roller guides G21 and G22 that guide the above-described straight stocks downstream, and the third guidance equipment on the most downstream side is contiguous to the second guidance equipment G2 and includes a plurality of bend-back forming roller guides G31 and G32 for bending back the above-described straight stocks in the laying head H direction to make them straight.
