Abstract

PURPOSE: To enable a high-speed-travelling sheet to be inked, without causing an ink stain to the inside of the sheet, by allowing a defective edge to contact a marking head and, at the same time, allowing compressed air to jet out from the sheet center to the sheet edge.
CONSTITUTION: When a defect is detected on a travelling sheet 4, the detection signal is transmitted to a electromagnetic valve 3 of an air cylinder 2 for pushing up a marking head 1, and a free-to-appear-and-retract marking head 1 is pushed up to the level of an edge section P of the sheet 4 and allowed to contact the edge. At the same time, blow air is jetted out in the direction of the edge section P from an air nozzle 9 whose piping is arranged from the sheet 4's top and bottom sides' center section toward the sheet's edge section P. As the air nozzle 9 is covered by an air flow adjusting box 10, the jetting air is adjusted and equalized in the box, so that a stabilized air flow is sent out toward the sheet edge surface.
