Abstract

The side flow long net paper making machine includes pulp distributor, long net, guide roller, return roller and table roller. The pulp distributor is supported with uprights over sides of long net, and consists of case container and pulp distributing port in the bottom opening of the case container. Inside the pulp distributor, homogeneous and dispersed pulp flow flows into the long net continuously to form homogeneous paper sheet.

Description

technical field [0001] The invention relates to a paper machine, in particular to a side flow fourdrinier paper machine. Background technique [0002] According to the different forming devices, the paper machine is divided into fourdrinier wire and cylinder wire. In the cylinder wire paper machine, according to the relationship between the rotation direction of the wire and the flow direction of the pulp, it is divided into forward flow type, counter flow type and side flow type. ;According to the different forming parts, the fourdrinier paper machine can be divided into fourdrinier wire, stacked wire and folder wire. There is also a side wave fourdrinier paper machine (see image 3 ), its shaper is Fourdrinier 12, but the slurry distributor 13 and Fourdrinier 12 are arranged laterally. Its slurry distributing device 13 is a wave bucket, and the wave bucket is arranged alternately on both sides of the fourdrinier net 12, and the number of the wav...
