Spray nozzles for the forming section in the paper industry
The forming section in the paper industry
The obtained mixture – mixed, diluted, dosed, and purified – is ready to be transformed into a sheet of paper.
The fibrous suspension reaches a metal container called “headbox,” the first part of the machinery that deals with paper production. We are inside the Fourdrinier machine, which has the task of carrying out all the phases of paper production. In this machine, the paper sheet is generated without interruptions.
This is the moment when the dough is distributed evenly and continuously on the paper forming net. In the forming section, the suction boxes – i.e., drawers below the canvas that progressively draws water- remove water from the fibrous tissue. At the end of the canvas area, the sheet has a water content of 60-70%. This phase determines the final weight and thickness of the paper.
