PURPOSE: An apparatus for preventing band marks on conductor rolls which restrains generation of the band marks by decreasing a surface profile between band and rubber of the conductor rolls only when a strip is contacted with the surface of the conductor rolls after passing through a galvanizing bath, thereby fundamentally blocking accumulation of zinc tree. CONSTITUTION: The apparatus for preventing band marks on conductor rolls comprises a circular band shaped installation groove(50) which is formed by partially cutting out the lower space of the rubber from the boundary surface of band(7) and rubber(8) that are coiled along the outer circumference of the conductor rolls to the side of the rubber(8); a plurality of brackets(30) which are projected from the bottom surface of the installation groove(50), that is, metal case(6); an inverted "Z" shaped operating plate(20) which is rotationally fixed to the brackets(30) by a fixing pin(28), wherein the upper supporting part is arranged so that one end of the operating plate(20), that is, the upper supporting part(24) is contacted with the upper surface inside the installation groove(50), and the lower supporting part is installed so that the other end of the operating plate(20), that is, the lower supporting part(22) is positioned at the upper side of the metal case(6); and a spring(26) one end of which is fixed to the lower end surface of the upper supporting part(24), and the other end of which is fixed to the metal case(6).
