Abstract: A double-layer forming wire for paper-making, cellulose and similar machines, said wire being particularly arranged to prevent marking on the material to be formed. The wire comprises two layers of weft yarns interconnected by warp threads, the weft layer intended to face the material to be formed (top layer) and said warp threads being essentially tangents to the plane of the wire intended to face said material. In accordance with a special arrangement the warp threads also bind separately with the layer of weft threads (top layer) intended to face said material. The invention likewise concerns a method of producing a forming wire of the above structure.

Abstract: A forming fabric for use in paper-making, cellulose or similar machines. The fabric comprising two layers of synthetic weft threads and synthetic warp threads. The latter interconnecting the weft thread layers but also binding separately the weft threads of the layer forming the paper making side of the fabric. The weft thread layer which forms the wear side of the fabric is tangent to a plane which is positioned outside the plane which is tangent to the warp threads interconnecting the weft layers.
