PURPOSE:To obtain a high accuracy width by finishing the front and rear ends having a relaxed strip tension by utilizing a biting rigidity at the final stand by installing a mill outlet side close edger positioned near to the outlet side of the final stand of a finish rolling mill. CONSTITUTION:An intermediate edger 7 installed in the downstream of a looper device 3 between rolling stands 1, 2 performs width screwing down of both width ends of a strip 5. A close edger 8 installed in a position near to the final stand 1 projects edger rolls 13 inside the guide face of side guides 10 for performing width screwing down. The width accuracy over the entire strip length is improved by a device with that composition. |
