Abstract
A device for controlling the production quality of a press, which manufactures package blanks from a sheet of material by transferring the sheet of materials, such as paperboard or corrugated board, chronologically through an infeed station, a die-cutting station, a waste-stripping station and a delivery station, has an arrangement for controlling the printing and blanking quality which includes a camera scanning the color register marks and a register mark for the positioning of the blanking of the sheet. The camera is located at the outlet of the die-cutting station so that it can scan the marks applied on the lower side of the sheet. The device includes a marking device, which is driven by the arrangement for controlling the printing and blanking quality, to mark a defective sheet and is positioned in the delivery station of the press.
