ABSTRACT:
This invention relates to an optical roll alignment device for aligning a roll pass in a bar/rod or section mill both with respect to the mating roll grooves themselves and an entry guide.
The device comprises optical means housed in a guide including a system of mirrors or prisms for providing an image of only the shoulders of the mating roll grooves, a lens system for magnifying the image and a screen or eyepiece in which the image is viewed, together with coordinates of the guide housing whereby any misalignment between the guide and the roll pass may be observed and corrected.
