Abstract (en)
[origin: WO2011076268A1] The invention relates to a system for transporting a fibre web (47) through a dry end of a fibre web processing machine from a drying section (1) to a reeling section (2) of the machine. According to the invention, the system comprises one or a plurality of groups of air modules, wherein each group of air modules is arranged for supplying and evacuating air from a predetermined, localized zone along the web run of the dry end, and wherein each group of air modules comprises at least one air supply module (9) being arranged for supplying air to the localized zone; and at least one air exhaust module (10) being arranged for evacuating air from the localized zone, wherein the air flow-rate of said at least one air supply module is balanced by the air flow-rate of said at least one air exhaust module such that dust-laden air is prevented from escaping the localized zone by other means than through said at least one air exhaust module.
