Description
Technical field
The present invention relates to field of papermaking, particularly relate to manufacturing installation and the method for a kind of soft thin-paged paper.
Background technology
Existing soft thin-paged paper its be all utilize a shaping cloth to coordinate with the format roll in wet portion in wet portion usually, the paper pulp flowed out from head box is carried out pressing, thus forms uneven paper width. Owing to also having one layer of woollen blanket outside format roll at cyclic motion, so shaping cloth is relatively big, less at the protuberance thickness of shaping cloth with the recess thickness at shaping cloth often making tissue paper during format roll pressing, although thickness difference is minimum, but still have impact on the distribution of paper pulp above paper, thus have impact on the quality of paper. And often wrinkle are too many due to the surface of shaping cloth, thus the roughness that can make paper surface strengthens, but when some, the soft thin-paged paper that such as we need its have and comparatively smooth can form again concavo-convex shape on smooth surface, this time, existing this kind of molding mode was often difficult to reach requirement.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of good forming effect, paper quality height, paper can be made to have the manufacturing installation of soft thin-paged paper width and the method for level and smooth concavo-convex shape effect.
