TH5460B - Process for controlled drying of the strip - Google Patents

Abstract

The disclosed process for drying paper sheets can be controlled at the time of drying in the paper machine. This process combines the process of winding a piece of paper with a string. The conveyor during the passage of the paper along with the said belt goes around the drying cycle of the drying phase and thereafter winds the paper around the guided section. It is positioned next to the dryer, so clumping at the edge of the paper is minimal.

Claims (3)

1. A process used for controlled drying of long strips of continuous paper strips with the wet end and the dry end of the paper machine drying process. Slide the paper strip and the dryer conveyor to Aligned or parallel to each other In such a way that the paper strips and belts The conveyor covers the hot surface portion of the rotary drier in such a way that the paper strips are positioned between the belts. Conveyor and hot surface, so the paper strip is controlled. Resists shrinkage in a transverse direction.The machine then guides the paper strips and the conveyor is parallel, which Each other immediately They follow each other around the vacuum guide wheels positioned next to the drier by placing the device so that the strip of paper is held by the belt. Conveyed as it passes through a strip of paper along a conveyor belt that Pulled between the drier and the guide wheels. In the manner that the belt The carrier wraps around the surface of the guide wheel - connecting the guide wheel with a vacuum source of at least 15.24 cm of the column of water in such a way that The vacuum is fed into the paper strip. Through the conveyor When the paper strip and the conveyor belt are wrapped around the guide wheel, the strip of paper is pulled closer to the conveyor belt. When the paper strip and conveyor are wrapped around the guide wheel, the device is positioned so that the paper strip will It is controlled to resist contraction in the direction across the machine during the scrolling of the paper strip around the guide wheel, and the paper strip and the conveyor are parallel to each other around the next drying dryer at the next position. Descend from the spinning wheel, guided by the dryer and the next drier Will be part of the drying episode Single pull type for drying the strip during Slide the next piece of paper strip down from the wet end. Of the episode of the drier, so the shrinkage in the cross direction Strip paper machine Especially during Dry the strips The dry end of the dryer section does not have to occur, so the wrinkling shrinkage of the paper strip is reduced. 2. The process described in claim 1 where controlled drying is achieved when the strip of paper is dry within the 40-60% range. 3. The process described in claim 1, where controlled drying of the strip of paper will proceed after the tab. Paper is more than 60 percent drier (3 claims, 2 pages, 19 photos).
