发明名称 Patterned paper and a method for manufacturing such
摘要 The invention relates to a multi-layered soft paper web, and a method for forming such. A multi-layered soft paper web consists of at least one layer, showing basis weight variations in a pattern. A base-layer of a fibre furnish is firstly formed on a wire (2), whereupon at least one top layer is deposited on top of the base-layer, which is supported by a wire or the like (3, 13, 113, 1113) under the applying of the top layer, whereby the top layer is deposited with a fibre suspension jet, and the hereby deposited top layer is formed with twin wire technology. A pattern is created in connection with the forming of the base layer, or at least one top layer by local redistributions within the layer of at least one substantial part of the solid material in the fibre furnish, whereby the pattern in said layer is created under simultaneous dewatering, and that the local redistributions are dependent of the pattern as well.
