Special paper forming net and paper making equipment for high speed paper machine

Abstract

The application discloses a special paper forming net and paper making equipment for high speed paper machines. The special paper forming net for the high speed paper machines is characterized in thatthe special paper forming net comprises a paper forming layer, a connection layer and a machine layer, wherein the connection layer comprises a paired first connecting warp and second connecting warpand is used for connecting the paper forming layer and the machine layer; the paper forming layer comprising a plurality of minimum organizational units is formed by interweaving polyester monofilament or nylon monofilament from 50 heald frames; the minimum organizational unit consists of weft and warp, wherein the weft, wherein the weft is formed by 50 polyester monofilament or nylon monofilament and the warp is formed by 36 polyester monofilament. With the above-mentioned method, the special paper forming net and paper making equipment for the high speed paper machines have the advantages that the provided paper forming layer and the machine layer of the special paper forming net for the high-speed paper machines are not easy to produce relative displacement on the high speed paper machines, wear inside the net forming net is thus slowed down, and service life of the net forming net is prolonged.

Description

technical field [0001] The application relates to the technical field of papermaking, in particular to a special paper forming wire for a high-speed paper machine and papermaking equipment. Background technique [0002] Papermaking forming wire is an important forming and dewatering material in the wet end of a paper machine. Commonly used papermaking forming wires include single-layer forming wire, double-layer forming wire, two-layer and half-layer forming wire and three-layer forming wire. Among them, three-layer forming wire is currently the most Commonly used papermaking forming wires generally include a paper layer, a machine layer, and a connecting layer including a pair of wefts for connecting the paper layer and the machine layer. [0003] The inventor of the present application found in the long-term research and development process that although the existing three-layer paper forming wire can basically complete the paper sheet forming and dewatering tasks, due to ...

Problems solved by technology

[0003] The inventor of the present application found in the long-term research and development process that although the existing three-layer paper forming wire can basically complete the paper sheet forming and dewatering tasks, due to its use of transverse stitching, the paper forming layer and the machine layer of the forming wire are at high speed. Relative displacement is easy to occur on the paper machine, and it is easy to cause accelerated wear inside the forming wire
