A forming fabric comprising an upper layer which is intended to serve as the paper-forming side and consists of thinner yarns, and a bottom layer which consists of coarser yarns. The two layers are interconnected in that threads form the upper layer alternately pass downwardy to interweave with the bottom layer and in the upper layer replace one another in such a manner that together these threads form the same weave pattern with the upper layer as the rest of the yarns in that layer, which yarns do not interweave with the bottom layer. |
