Pulp is pumped from the machine box through the screens and cleaners to the head box.  The purpose of the head box is to deliver a uniform slurry to the polyester forming fabric.There are several different designs, but all incorporate a method to induce turbulence (deflocculation), while preventing cross currents, which would inhibit the uniformity of the stock. 

The pulp flowing onto the polyester forming fabric is approximately 0.5-1.0% fibers, with the make-up consisting of water.  As the water is removed from the slurry, the fibers settle onto the surface of a traveling wire, forming a wet mat of paper.  Therefore, the main objective of the forming section is the controlled removal of water. 

As the slurry exits the slice onto the polyester mesh, the water starts draining from the suspension. Water jets are positioned over the edges of the forming wire to control the width of web, creating what’s called the deckle edge.  The first fibers forming the mat on the wire are oriented in the direction of the machine; this is the wire side of the paper.
