Abstract
A desirable embossing of a fibrous web (6) as dry laid on a forming sheet (2) is effected by the web (6) in a still unglued condition passing a pair of embossing producing rollers (18, 20) carried on or by a pressure resistant support sheet (16) as also passing between the rollers. Problems as to web fractures are hereby widely eliminated.
