Abstract

Process for the manufacture of transversely extensible paper articles, in which: a sheet of wet paper is formed, this sheet is pressed and dried, this sheet is subjected in wet state, during its manufacture, to a shrinkage obtained by placing contact with a perforated elastic band, previously widened, which is then left to contract, the method being characterized in that: the humidity of the sheet is comprised between 80 and 90% the perforated elastic band is the first felt located after the forming zone the sheet, the contraction of the felt and the wet formed sheet are made before the first pressing.
