Doctor Blade of Paper Machine Press Part

Problems that are likely to occur during pressing include the following: crushing, falling edges and folds, indentations, and paper holes. Paper holes are mainly caused by the looseness of the four-press doctor blade, so the doctor blade is very important in the paper making and pressing process.

When the pressing moisture is high, paper wool is easy to stick to the surface of the lower roller. Too much paper hair will push up the doctor blade and cause indentations on the paper. After the upper roller doctor blade is pushed up, the paper hair on the doctor blade can easily escape the doctor blade and fall onto the paper surface, causing paper holes. However, Leizhan’s doctor blade can effectively solve this problem through technological improvements.
