METHOD AND APPARATUS FOR FORMING SHEET OF FLUFF PULP Russian patent published in 2016 - IPC D21F1/08 

FIELD: textiles, paper.

SUBSTANCE: described are improved methods of making sheets of fluffed cellulose, which are mechanically eliminated many of undesirable links between fibres (bundles of fibres), which can be contained therein to get monotonous flaked cellulose of a single quality. Liquid mass is fed onto moving bottom forming grid to form a web. Liquid mass is brought into contact with moving top forming a grid. Web is subjected to upper and lower dehydration, thus creating separately formed layers in order to reduce communication between fibres. Web may be subjected to high pulsating shifting forces, when it passes along lower forming grid to damage majority of bundles of fibres contained in web. Liquid mixture can be fed to bottom forming net using pressure box with dilution control device to selectively regulate concentration of liquid mass. After web is subjected to action of pulsating shearing forces for dehydration cloth can be used for shoe press. Web may be dried using traditional equipment for drying, such as cylindrical drier.

EFFECT: monotonous flaked cellulose of a single quality.
