The present invention relates to a wiper for removing foreign matter on the surface of the strip during the rolling of the strip in the cold rolling line of the cold rolling mill, and by installing a plurality of wipers on the rotating block of three sides according to the wear state of the wiper The present invention relates to a wiper device for removing foreign substances on the surface of a strip, which can improve the manufacturing productivity of the strip by preventing the foreign matter attached to the surface of the strip by rotating to prevent the operation of other rolling lines in small replacement of the wiper.

Generally, in the production of strip coils such as stainless steel sheets, in a cold rolling line of a cold rolling mill, strips reciprocated as PAY OF REEL and TENSION REEL are multi-stage rolling mills, that is, about 10 parts in the upper and lower parts. Rolling work is carried out with a rolling mill equipped with a rolling roll, in which foreign materials are caught between the strip and the rolling roll during the rolling operation of the strip, or surface defects of the strip or rolling failure due to oil applied to the strip and excessive use of the rolling oil. In order to prevent the installation of a wiper for removing foreign matter on the surface of the strip, such a conventional wiper for removing the foreign matter on the surface of the strip is shown in FIG.
