How a paper machine line works? Pack 6

Headbox and wire section; a paper machine’s web forming section consists of a headbox and wire section. This is where many of the important paper properties are determined. The headbox dispenses pulp evenly onto the wire mesh for the entire width of the machine. The most common wire section types are the fourdrinier, hybrid former and gap former. The wire section is where the water from the forming web is removed by drainage and thickening.

Press section; the press section removes as much water as possible from the paper web and compresses it. Felt is used to convey the web through the press nip formed between the press rolls. Wet pressing has a significant affect on paper properties. When the paper’s wet strength is good, the paper web can withstand the move to the dryer section without breaking.

Dryer section; in the dryer section, water is removed from the paper web by evaporation. The aim is for evaporation to occur efficiently, economically, evenly, and without compromising paper quality. Methods commonly used in drying paper and board are contact or cylinder-drying, blow drying, and radiation drying.
