METHOD AND EQUIPMENT CONCEPT IN THE CUTTING AND THREADING OF THE LEAD-IN STRIP OF A PAPER/BOARD WEB IN THE FINAL END OF THE DRYER SECTION OF A PAPER/BOARD MACHINE

摘要

The invention concerns a method and an equipment concept in the cutting and threading of the lead-in strip (20) of a paper/board web in the final end of the dryer section of a paper/board machine. In the method the paper or board web (W) is passed over drying cylinders (K1, K2,...) and suction cylinders (S1, S2,...) further while meandering in loop shape. The lead-in strip (20) is cut by means of a cutter (10) before the last drying cylinder (K4) in the group (Rn). After cutting, the lead-in strip (20) is passed onto said drying cylinder (K4) and further from the drying cylinder (K4) onto the suction cylinder (S2). From the suction cylinder (S2) the lead-in strip (20) is passed further onto a guide roll (E, E10, E20).
