1.1 General description概述
●The top former consists of an upward dewatering device placed on a flat table of Fourdrinier type equipped with a counter-wire destined to:
●安置在长网纸机网案上,由纸幅顶面脱水元件所构成的顶网成型器，装配有一张顶网，其目的:
-Drain the water from the top surface of the sheet从纸页表面脱水
-Improve the sheet formation and the 2-sideness改善纸页成型及两面差
-Improve the print quality 改善印刷质量
-Improve the bulk of the sheet改善纸页厚度
-Improve the drainage 改善脱水
●Hence allowing to decrea the headbox consistency and/or to increa the dryness at the suction couch roll outlet, resulting in a highter production rate of the paper machine.
●提高上网浓度和湿纸幅出真空伏辊的干度，所以可以提高纸机的生产车速。

1.2 Top former main elements descriptions 工作签证移民主要部件说明
1.2.1 Lead-in box(2) 导入箱
●Located inside the bottom wire loop. During the erection, the adjustment is made to give a perfect tangency of the wire with regard to the inlet and the CIVB. It is done by screw and shims.
位于长网底下。安装时，通过调节螺丝、垫片使网部与入口、CIVB能够完全相切。
●The curved box is compod of two vacuum compartments and fitted with blades. The position of the Nip between the two wires with regard to the autoslice defines the time of forced drainage of the sheet water and conquently has an influence on the formation and the orientation of the sheet fibers.
弧形箱由两个真空室组成，并装有刮水板。自动刮水板两网间压区的位置，决定了纸页强制脱水的时间并影响纸页的成型及纸页纤维的定向。
●The applied vacuum level is low.
提供的真空度较低。
1.2.2 Lead-in roll (22) 导入辊
●The lead-in roll can be lowered or raid while machine is running. The position of the roll is given by an index and a graduated scale.
机器运行时，导入辊可升高或降低。导入辊位置可通过指针和刻度尺得出。
1.2.3 Auto-slice asmbly (8) 自动调节刮水板
●The autoslice is the first element of the CIVB, and has a compartment to recover the water by skimming from the inside of the top former wire. The side glass is equipped with an internal shower to keep it clean.
自动调节刮水板是CIVB的首要部件，其有一隔室收集从顶网内部脱出的水分。端面玻璃上安装有内部喷淋水管以保持刮刀的清洁
shills●The water is evacuated by action of the top lip to the CIVB 1st compartment.
通过上刮水板唇边缘动作将水撇至成型器的第一个隔室里
职称外语成绩查询●A manual operated screw jack moves the lip of the auto-slice. The possible range of the top lip wire gap adjustment is from 9 to 25 mm。
真空刮刀的唇刃可以手动操作螺杆调节。上刮刀唇刃的线差调节范围为9~25mm

1.2.4 counter blade asmbly (9) 倒置刮水板
●Located inside the bottom wire loop, opposite the CIVB, it removes water from the Bottom wire due to the skimming effect of the blades.
位于底网回路，与顶网成型器相对，通过刮水板的撇取作用将底网的水分脱除
●The pressure puls created by the blades creates shear forces which help to improve paper formation.
刮水板产生的强制剪切力引起压力脉冲，帮助改善纸页成形
●Air tubes move the blades to working or retract position
气缸动作可以将刮水板进入工作位置或转换到起始位置。
●Adjustment of the position of the counter blade asmbly box/wire is done at start-up by adjustment screws.
在启动前，可以通过调节螺杆来调节刮水板元件、真空箱/网的相对位置
1.2.5 CIVB (1) 弧形倒置真空箱
●The inverted curve vacuum box has 3 chambers with progressive vacuum to remove the water of the top side of the sheet. It improved the fines and fillers distribution on the z-direction of the sheet and reduces the 2-sideness.
弧形真空吸水箱有3个真空度逐渐升高的隔室以便脱除纸页顶面的水分。它可以改善细小颗粒和纤维在纸页z向上的分布及减少两面差greenland
●Chambers are equipped with tending side windows for visual operator asssment of the water level.
真空室装有观察窗以便操作员估定液位。
●Adjustable deckles allow to adjust the CIVB to the sheet edges.
