ABSTRACT:
The known mill roll stand in a feeding apparatus of a rolled sheet of the type including at least one pair of arms having rolling centers at their tip ends and constructed so as to be swingable about an arm shaft at their base ends and so as to be movable along the arm shaft to approach to or separate from each other, is improved so that when the rolling centers are raised by swinging up the arms so as to meet with sheet rolls having different roll diameters, the rolling centers may be raised along a vertical straight line locus rather than an arc-shaped locus. The improvements reside in that the opposite ends of the arm shaft are eccentrically and pivotably supported from rotary supports on a frame of the mill roll stand, and that there is provided converter mechanism for converting the swinging locus of the rolling center into a locus along a vertical straight line.
