PURPOSE:To prevent the abnormal abrasion of a rolling roll in a rolling method of a strip which is cut in the transverse end parts by rolling the strip while removing burrs and sharp angles in the end parts produced by the cutting. CONSTITUTION:A metallic strip 1 is coiled and is worked in the end parts thereof with polishing rolls 3 provided right before the rolling mill of a rolling line or right after the cutter for the transverse end parts. If such strip 1 is rolled with a rolling mill consisting of work rolls 2 and backup rolls 4, the rolls 2 are kept free from scratching by the cut surfaces in the end parts having burrs and sharp angles. The end parts contact smoothly with the rolls 2 and are supplied satisfactorily with lubricating oil; therefore, the rolls 2 have no edge marks. |
