Abstract
A roll chucking apparatus is disclosed. The roll defines opposed side openings. The roll chucking apparatus includes a platform from supporting the roll. Lift structures vertically adjust the platform. Sensing structures sense an increase or decrease in the platform load upon the attempted initial insertion of opposed chucking pins into the opposed side openings. The lift structures vertically moves the platform and the roll until correct vertical alignment with the chucking pins occurs.
