singly produced arkmaterial based on cellulose fibres and process and apparatus for the production of arkmaterial

摘要

The present invention relates to a sheet material manufactured piecewise and having a dry solids contents exceeding 90 % and comprised at least partially of cellulose pulp fibres, characterized in that the material contains a) a mixture of filler and pulp fibres deriving from the manufacture of paper and recovered in the form of sediment, in an amount corresponding to at least 30 and at most 95 % of the weight of the sheet material; and b) pulp fibres in the form of virgin fibres and/or secondary fibres, essentially as reinforcing fibres. The present invention also relates to a method and to an apparatus for manufacturing sheet material based on cellulose pulp fibres.
