ABSTRACT:
A backing screen runs together with the paper web through the drying section of a paper machine. The backing screen bridges the space between the press section and the drying section. For threading the so-called transfer strip through the drying section there is a rope carrier provided whose ropes run outside the paper web width. Prior to its insertion at the entrance point of the rope carrier, the transfer strip, which is separated from the backing screen, is passed across a mechanical guide element which, sideways and from the outside, can be moved into the area of the backing screen and back again. The mechanical guide element is movable so that the space between the guide element and the backing screen is variable.
