Abstract
There is described an inspection system () for inspecting the quality of printed sheets which are transported by a sheet conveyor system comprising at least one sheet gripper system () including a plurality of spaced-apart gripper bars () for holding the printed sheets by a leading edge thereof. The inspection system () comprises an optical quality control apparatus for carrying out inspection of a first side of the printed sheets while the printed sheets are being transported by the sheet gripper system (). The optical quality control apparatus includes a line camera () for scanning the first side of the printed sheets at an inspection location which is situated at a location proximate to a portion of the sheet gripper system () where the gripper bars () transporting the printed sheets undergo a change of direction of displacement while the printed sheets are still being scanned by the line camera (). The inspection system () further comprises a suction roller () that is placed in front of the optical path (B) of the line camera () along the path (A) of the printed sheets being transported by the sheet gripper system (), which suction roller () contacts a second side of the printed sheets opposite to the first side which is being scanned by the line camera (), the suction roller () being driven at a selected circumferential speed to drive successive portions of the printed sheets being inspected by the quality control apparatus at a determined and controlled speed past the line camera ().
