In the Condebelt process the sheet is dried against a smooth and hot surface under z-directional pressure. In addition to improvement in the drying rate there are beneficial effects on sheet properties. In this experimental study the effects of several variables on board structure and properties were examined. Two fibre materials, mechanical and chemical pulps, were compared. The effects of drying temperature (110-180 oC), drying pressure (1-5 bar), and solids content of the sheet were studied. The results indicated that the board properties can be varied extensively and new combinations of properties achieved. The results demonstrate the very promising potential of the Condebelt process.
