Abstract

Wet papermaking sheet is made, pressed and dried. It is subjected during fabrication, in the wet state, to a contraction produced by contact with a perforated elastic belt, previously extended and then allowed to contract. The sheet moisture content is 80 - 90%. The belt is the first felt after the formation zone. The contraction of the felt and the sheet is performed before the first pressing. Apparatus is described.
