VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINER NEUEN PAPIERQUALITÄT

The procedure for the production of multiple roll calendaring paper, carton or other fiber product, comprises guiding fiber web produced with a machine intended for the formation of fiber web from final drying element of the machine to following production process, and guiding the web for the treatment to repeated roll calendering. Before calendaring and after the final drying, a treatment agent is applied by a double-sided dispenser, which is a spray dispenser (5), a film transferring-paper coating device or other device suitable for dosing. The procedure for the production of multiple roll calendaring paper, carton or other fiber product, comprises guiding fiber web produced with a machine intended for the formation of fiber web from final drying element of the machine to following production process, and guiding the web for the treatment to repeated roll calendering. Before calendaring and after the final drying, a treatment agent is applied by a double-sided dispenser, which is a spray dispenser (5), a film transferring-paper coating device or other device suitable for dosing. A water-content profile is adjusted in transverse direction of the web for the web with a profiled moisture regulating device. The treatment agent quantity applied by the dosing device and the moisture regulating device are adjusted in such a way that the moisture of the web lies at a certain point on a certain level and the moisture profile corresponds to the desired profile. The treatment web is rolled up with a rewinder (3) to a roller and conveyed as roller to the treatment to the repeated roll calendering to which the treatment web is led directly. The moisture is regulated with a profiling or non-profiling dryer by speed change of the web. The maximum quantity of the treatment agent corresponds to 1g/m 2>of the drying agent of the treatment agent in the end product per product surface. The treatment agent consists of a starch containing surface glue and of a polymer based treatment agent or other suitable chemicals. Two propagations are formed for the web between the final drying roller and the rewinder and/or calender. Independent claims are included for: (1) a device for the production of multiple roll calendaring paper, carton or other fiber product; (2) procedure for raising the processing grade of an available production line producing a multiple roll calendaring fiber product; and (3) multiple roll calendaring paper.
