本発明は抄紙機におけるシートの脱水方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for dewatering sheets in a paper machine.
本発明＃′）目的は脱水前の濡れたシートの脱水率を著
しく向上させることにある。繭記の目的な充足するため
本発ｅＡは次のように構成したものである。The object of the present invention #') is to significantly improve the dehydration rate of wet sheets before dewatering. In order to fulfill the purpose of Cocoon Records, the present eA is constructed as follows.

ことによってシートの温度を上げ。That is, in this invention, the surface of the sheet tttxK steaming A before completion of dehydration moving on the wire in papermaking seconds is brought into contact with and heated, and the steam is brought into contact with the water contained in the sheet, and the Nakushi heating box is heated. Raise the temperature of the seat by suctioning with the Aisha Enakushi 5 Noblesse.

-4, sa--y x ---Infiltrate the interior of the sheet. The latent heat of the steam is converted into the sensible heat of the water, and the dehydration of the sheet is carried out smoothly and rapidly. Also, since the dehydration rate of the sheet is low in the central part along the flow direction, the pulp sIy is operated appropriately to apply a particularly large amount of steam to the central part of the jujube chamber 7, and a smaller amount to the left and right chambers 1. The dehydration process is carried out rationally by sending steam. In the figure, 10 is a computer, U is a moisture meter, and it is also possible to directly connect the moisture meter n and computer 10 to the unit to automatically calculate the moisture content tv4.
本発明和よればシートの脱水率は著しく増進し効果的に
紙を製造することができる。According to the present invention, the dewatering rate of the sheet is significantly improved, and paper can be effectively produced.
