Abstract
A method for feeding material sheet to a press comprises steps of transferring a material sheet on which print parts and the corresponding positioning marks are printed for a preset distance at least until the positioning mark comes into the field of view of a viewing device provided in a position related to the working position of the press, detecting misalignment between the centers of the positioning mark and a reference mark of the field of view in the X and Y axis directions by the viewing device, and positioning the print part at the press working position automatically and precisely by using the detected amount of the misalignment as a correction value for positioning.
