Valmet Fourdrinier Former

The Fourdrinier type wet end provides extreme flexibility for varying production rates, basis weights and pulp qualities, thanks to several adjustable parameters including headbox slice. In addition, the Fourdrinier type features long wire lifetime and disturbance-free operation. For maximized dewatering the Fourdrinier can be furnished with a top former. Alternatively, the top former can be installed at a later stage when an increase in production becomes necessary.

Valmet Gap Former is the result of continuous development

The Valmet Gap Former represents the latest evolution of double-wire formers featuring effective, controlled two-sided dewatering. Web formation takes place in a fully controlled, adjustable former section. 

The Gap former utilizes mechanical dewatering methods in all consistency areas and thus avoids practically all such losses. In low consistency area from the headbox to the sealing unit, water is removed in an airless, controlled former section.
