Abstract
PURPOSE:To make possible the roll to be pulled out at any position without axially moving the roll, by installing the stepped protuberance in the spacer, and by fitting this protuberance into the fitting hole of the metal chock. CONSTITUTION:At pulling out the roll, the spacer 36 is inserted into the gap of the metal chocks 10, 5, and the stepped protuberance 38 is fitted into the stepped fitting hole 35 of the metal chock 5 on the side of the work roll 3; then, the work rolls 3, 4, are pulled out of the housing by outward pulling through the grip 39. When the protuberance 37 hits the side wall on the outer end of the concave 33, the intermediate roll 8 is pulled out through the metal chock 10. Meanwhile, at putting the roll into the housing, the spacer 36 is turned over upward and downward, and the tip of the stepped protuberance 38 is fitted into the fitting hole 34 of the metal chock 10, and the protuberance 37 is fitted into the large diameter part of the fitting hole 35. Under this condition, the working rolls 3, 4 are put into the housing; as a result, the axial relative position of the working roll and the intermediate roll is made constant.
