• a lower roll journaled in said lower-roll journaling insert bodies and an upper roll journaled in said upper-roll journaling insert bodies for rolling a workpiece between said rolls, said rolls and said bodies being jointly removable from said stand in an axial direction by locking of said upper and lower bodies together;
• and
• supporting beams bridging said uprights across a path of said workpiece through said stand and received in said windows on opposite sides of said bodies in each window, each of said supporting beams having guides extending substantially the lengths of said beams, said insert bodies having feet receivable by said guides for displacement of said rolls and said bodies jointly relative to said beams upon removal from said stand in said axial direction, said supporting beams being formed with mutually aligned openings permitting passage of said workpiece therethrough as said workpiece passes between said rolls.
