Size Press

Size press (application press)  is put directly in paper machine after pre-drying section. It is made as two roll press with inclined presses axis. The load is deduced through lever mechanism with hydraulic or pneumatic pressure. The pressure is controlled according to technological demands from 0 kN/m to maximal load. 

Coated medium (for instance mixture of starch, sizing agent, AKD, pigment etc.) is transported to dosing chamber and proceeds to the calibrating space. Amount of applied starch on paper surface is here calibrated by use of profiled bars.

Press rolls are designed on maximal load and dynamically balanced on demanded speed and covered with special coats depending on produced paper kind. Bearing structure is made of common or stainless steel according to customer's inquiry. Profiled bars have diameter 10 - 38 mm and are made from stainless steel with chrome plated cover.

Paper surface treatment

surface sizing - to get an effective quality improvement of produced paper and reduce sizing agents consumption due to their better retention (compared to sizing in substance)surface treatment by use of special agents - to reach hydrophobic, greaseproof properties etc.surface dyeing - costs saving compared to dyeing in subs-tance, reaching of special color effects and reducing of waste water pollutionhin layer of special coats
