    摘要： A widthwise bend of an end of a hot-rolled elongate sheet-shaped metal product (1) is corrected while it is hot. The correction comprises simultaneously:

    (i) holding the edges of the product (1) at at least two positions (12,13) longitudinally spaced along the product thereby to hold, at least laterally, a portion spaced from the bent end, and
    (ii)pushing the end portion laterally by means of a laterally moving member (14). The method may be performed while the product is continuously moving along a path. Both steps (i) and (ii) are performed by rollers rotatable about vertical axes.

    摘要： A rolling mill for rolling metal strip (11) moving in a horizontal rolling direction, has work rolls (1) which engage the strip and are supported vertically by backup rolls (2) through which drive is applied. The work rolls (1) are supported in the horizontal rolling direction by support rollers (4) contacting them at locations confined to intermediate regions between the work regions and bearings (8). The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means (5,7) for the support rollers operable to move and locate the support rollers so as to shift the work rolls (1) to a predetermined location at which the vertical axial plane of the work rolls (1) is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls (2). The support rollers (4) maintain the work rolls at the predetermined location during rolling.

    摘要： An apparatus for looping belt-like materials, i.e. strips (1), comprising first and second looping units for winding a moving belt-like material helically into first and second coils (23, 30), a means for drawing out the portion of the belt-like material (1) which constitutes the first coil (23), into the second coil (30), a plurality of support rollers (24, 25) arranged annularly along each of the portions of the wound belt-like material (1) which constitute the first and second coils (23, 30), frames (54) provided with the support rollers (24, 25), driving means for applying the rotary force to the frames, and means for applying the rotary force to the frames, and means for displacing the support rollers (24, 25) in the radial direction of an imaginary circle, along which the support rollers (24, 25) are arranged, in accordance with variations in the diameters of the coils (23, 30) so as to bring the support rollers (24, 25) into contact with the portions of the belt-like material (1) which constitute the coils (23, 30), the support rollers (24, 25) being arranged annularly along inner circumferential surfaces of the coils (23, 30), the drawing means being provided with a plurality of small-diameter rollers (27, 28), which are arranged along a curved surface (26) of an imaginary cone or cylinder in such a manner that the small-diameter rollers (28) can be rotated in the same direction, in which the belt-like material (1) is drawn out. When the above-described construction is employed, slipping can be prevented from occurring between layers of a strip (1), i. e. the portions of a belt-like material which form the coils (23, 30), while the strip (1) is moved, and a high-quality strip can be obtained.

    摘要： A different circumferential speed continuous rolling mill including a plurality of rolls (1,2,3,4;5,6,) including one roll cooperating with other rolls to roll a trip simultaneously at a plurality of rolling points to continuously roll the strip by rotating the one roll at a circumferential speed distinct from the circumferential speed of other rolls is equipped with a tension difference applying device (7,11,12;8) located in a path of travel of the strip between a first rolling point at which the strip is brought into contact with the one roll and rolled thereby and a second rolling point at which the strip is brought into contact with the one roll again and rolled thereby after clearing the first rolling point, so as to thereby create a difference in the tension applied to the strip between a portion of the strip located at an delivery end of the first rolling point and a portion of the strip located at an delivery end of the second rolling point. The tension difference applying device is operative to increase the tension applied to a portion of the strip located between the first rolling point of the one roll and the tension difference applying device and decrease the tension applied to a portion of the strip located between the tension difference applying device and the second rolling point of the one roll. Thus rolling energy can be fed to the strip not only from the rolls but also from the tension difference applying device to enable continuous rolling with a high degree of efficiency.
