flowbox

A flow box is a mechanical reservoir in a papermaking machine that supplies beaten paper pulp to the wire. This pulp is then formed into a sheet, pressed, dried, and wound into reels. Paper machines can vary greatly in size and production capacity. Modern machines often feature advanced headboxes that ensure a consistent flow of stock across the entire width of the machine, crucial for creating a uniform paper weight. The process involves several stages, including sheet formation on a wire screen, pressing to remove water, and drying through heated cylinders.12
