Abstract
A method for the manufacture of a sheet containing mineral fibers and binder. An aqueous suspension containing fibers and binder is formed into a layer. The layer is de-watered to form a wet sheet. Additional binder is applied evenly to the entire surface of the de-watered sheet. The sheet is then dried. The sheet may be compressed to an extent of 20% during drying.
