Crescent former serves as wire part for production of tissue papers with substance weight from 12 g/m2 on the wire (i.e. 14 g/m2 on the reel) at design speed up to 1,500 m/min. The dewatering proceeds through centrifugal force on forming roll.

Design

Bearing structure is cantilevered, made of stainless steel resistant against corrosion and adapted for easy and speedy wire and other elements exchange. Set of special troughs and covers for water discharging from the former is part of its structure. There is a wire deflector in frontal part designed as slip out to ease cleaning and maintenance of the equipment. Main part represents forming roll with special cover enabling an intensive dewatering between forming wire and felt which contributes to very good fibres formation. Other parts are elements for stretching, guiding and conditioning the wire.
