Abstract
A rolling mill apparatus for forming a web of material includes a die stand having an upper die assembly and a lower die assembly, the die stand bending the web to a predetermined formation angle as the web passes between the upper die assembly and the lower die assembly. A movement apparatus is utilized for selectively moving the upper die assembly in a vertical direction, thereby adjusting a vertical clearance between the upper die assembly and the lower die assembly. A pin is fixed to the upper die assembly and a cam block having a groove formed at a predetermined orientation angle is also provided. The pin travels in the angled groove when the upper die assembly is moved in the vertical direction and causes the upper die assembly to move horizontally. The predetermined orientation angle of the block is approximately equal to the predetermined formation angle.
