ABSTRACT:
A dryer screen in a paper machine has two superimposed connected gauze structures. It has a surface gauze layer an a bottom gauze layer, each having respective weft threads (1, 3) and warp threads (2, 4). In the dryer screen, the warp threads (2, 4) are similar in both the surface and bottom gauze layers, and they are similar in cross-section. The warp threads (4) of the bottom gauze layer pass at suitable intervals over the weft threads (1) of the surface gauze layer to bond the bottom and surface gauze layer together. The cross-sectional area and shape of the weft threads of the bottom gauze are selected so that the respective actual lengths of the warp threads (2, 4) of the surface gauze layer are equal to the corresponding threads of the bottom gauze layer.
