摘要:
The invention concerns an equipment and a method in the transfer of a paper/board web in a paper or board machine. In an embodiment of the invention, the dryer section comprises at least one group of drying cylinders in which, instead of a conventional wire draw, a transfer belt (H100) is employed, to which the web (W) is affixed by effect of adhesion and which transfer belt is passed over drying cylinders (K1, K2, . . . ) and reversing rolls (E1, E2, . . . ) and further in said group (RI) of drying cylinders in the dryer section. The invention also concerns a method in the transfer of the web (W) in the dryer section (K) of a paper/board machine. In an embodiment of the invention, the web (W) is passed, while meandering in loop shape and while adhering to the face of the transfer belt (H100), from a drying cylinder (K1) in the group (RI) of drying cylinders in the dryer section (K) onto a reversing roll (E1) and further from the reversing roll onto the next drying cylinder (K2) and further in the group (RI) of drying cylinders.
