摘要

An apparatus for preventing a scratch of a strip is disclosed. According to an embodiment of the present invention, the apparatus for preventing a scratch comprises: a pair of rollers rotationally connected to both ends of an expansion support arranged to be expanded to be spaced so as to face each other; a pair of belts coupled to maintain predetermined tension by covering a circumference of the rollers in two different positions with respect to an axial direction of the rollers; and a pair of push units individually supporting an inner surface on an upper side of the belts in two different positions with respect to a rotational direction of the belts, and individually lifting a support portion of the belts moving to and corresponding to a strip by a magnetic force when the strip sags.
