In a multi-ply handsheet there are three fundamental strengths. These fundamental strengths are the bonding between plies, bonding between fibers and the strength of the fibers. The strengths are interrlated and controlled by the preparation and mechanical handling of the stock.
The beating of the fibers, the consistency at which the sheet is formed, the couching pressure, and the final pressing all produce certain marked effects on the strength characteristics in a multi-ply handsheet.
In general it may be said that the strength characteristics of a given weight sheet may be increased by forming a multi-ply sheet.
