ABSTRACT:
A sheet of material is printed with a plurality of printed portions to be punched as a plurality of positioning marks near said printed portions. A camera is provided for a press machine for detecting center positions of the mark and the printed portions are positioned at a punching portion of the press based on the detected center positions Vacuum sucking means are provided to such the sheet mounted on a table and obliquely moving the sheet until its edge engages a stop member which corrects the attitude of the sheet. When a defective printed portion is detected, punching thereof is prevented. The apparatus is constructed to minimize the stroke of movement of the sheet during the steps of supplying and positioning it to the press machine and discharging a scrap remaining after punching the sheet.
