Abstract:The BTFTM dilution control technology consists of a radial distributor, which replaces the headbox tapered header, and a dilution water system, which replaces slice lip profiling to control the basis weight profile. This system can be retrofitted to almost any type of existing headbox, or it can be supplied with a new hydraulic headbox. The technology has been installed on more than 190 paper machines worldwide and has provided substantial improvements in CD profile and in sheet quality.
