Abstract
802,459. Rolling. MURAKAMI, Y. Aug. 23, 1956, No. 25796/56. Class 83 (4). In a rolling mill for metal strip or sheet the working rolls 10, Fig. 1, are supported by driven intermediate rolls 8, 9 which are in turn supported by a single upper backing roller 12 and a pair of spaced lower backing rollers 16 which are so distributed along the intermediate rolls as to impart the same strain curvature #, #, Fig. 5, to the upper and lower rolls 10 so. that a uniform thickness of material is obtained across the width. The working rolls 10 are supported without journals between end blocks 26 and are held in position by two rows of supporting rollers 20, Fig. 2, engaging opposite faces of the rolls and mounted in brackets 21 attached by bolts to the housing 11. The single upper backing roller 12 is mounted between bearing boxes 13 to which pressure is applied through a pair of screw downs 19<SP>11</SP>, 19<SP>111</SP>. A second pair of screw downs 19<SP>1</SP> 19<SP>1111</SP> apply pressure to the roll chocks 14 of the intermediate upper roll 9, to produce the strain curve #, Fig. 5. The lower intermediate roll is supported by the pair of backing rollers 16 running on spaced bearing boxes 17, 18 to give a strain curve #, Fig. 5, of similar shape. The drive for the intermediate rolls 8, 9 is provided by a motor 1 through a differential gear 5 and spindles 6.
