<p>A papermaking machine section for dewatering or drying a wet paper web, comprising a papermaking endless fabric (100) configured to support a wet paper web (75) for dewatering, the fabric (100) comprising a permeable portion (275) and a pair of laterally spaced apart strip portions (250) extending along the fabric in the machine direction, each strip portion being impermeable to air and defining said permeable portion therebetween. According to the invention, the permeable portion is adapted such that the wet paper web supported thereby extends over the entire width thereof, whereby the permeable portion is configured to allow air directed thereat to flow therethrough, exclusively of the permeable strip portions, such that the wet paper web supported only by the permeable portion is dewatered, the width of the permeable portion between the impermeable strip portions thereby defining a corresponding width of the wet paper web being dewatered. At least one processing device is configured to provide a flow of air, said fabric being configured to interact with the at least one processing device.</p> |
