ABSTRACT OF THE DISCLOSURE The specification describes a clothing for the sheet forming section of a papermaking machine comprising two layers of transverse threads and longitudinal threads 5 interwoven with both layers of transverse threads 3 and 4. Both the paper side and the running side have trans- verse structure and the number of transverse threads in the upper layer is twice as high as that in the lower layer 2. The longitudinal threads 5 interweave twice in each repeat with the upper layer and with the lower layer. Interweaving with the upper layer is effected one time with a transverse thread 3a lying above a transverse wire of the lower layer, the other time with a transverse thread disposed midway above two transverse threads of the lower layer. At the point of interweaving of the lower layer, two adjacent longitudinal threads are disposed side by side, one longitudinal thread inter- weaving, at one point of interweaving, together with the preceding longitudinal thread and, at the next point of interweaving, together with the next following longitudi- nal thread.
