ABSTRACT:
A forming wire for use in paper-making, cellulose and similar machines, comprising a first layer of weft threads, which layer is intended in the position of use of the wire to face the material to be formed, a second layer of weft threads, which layer is intended in the position of use of the wire to face the machine drive rollers, and synthetic warp threads interweaving said two weft layers. Said first layer of weft threads crosses said warp threads on said outer face of the wire closest to the material to be formed, in at least 80% of all cross points, or according to the shaft (harness) number used in between 80% and 90% of all cross points, whereby the wefts on the wire face turned towards the material to be formed float over a large number of warps. The number of cross points on this wire face thus is reduced, eliminating the tendency of the wire to cause marking on sensitive paper qualities.
