Abstract: A method for drying a cellulose web, in particular a moist paper web evincing a dry-state specific surface weight of between 10 and 80 g/m.sup.2 and initially a solids content between 8 and 30% approximately, and including supporting the web on a permeable conveying fabric and having a high-speed flow of hot air pass through the web, is characterized in that the flow of air is generated by a relative negative pressure of 100 to 500 mbars generated underneath the fabric.

Abstract: The invention relates to a hydrophilic cotton lap constituted 100% of cotton fibers. In the invention, the lap is a composite and comprises three cotton layers evincing inter-cohesiveness arising from a continuous lap manufacturing procedure. The external layers and enclosing the central layer are webs. The lap of the invention is used in the form of packaged or formatted units of hydrophilic cotton.

Abstract: The multi-layer paper composed of at least three embossed plies of paper (1,2,3) having regularly distributed projections characterized in that it includes two so-called external plies (1,3) of which the respective projections (10,30) are in tip-to-tip positions and a third embossed so-called middle ply (2) of which the projections (20) nest between projections of one of the two external plies (1 or 3).

Abstract: A method for embossing a sheet of creped paper composed of at least one ply, whereby the sheet is engaged between two metallic cylinders fitted with protrusions and driven in rotation in a conventional manner and mesh with each other while having a play e1 between the tops of the protrusions of one cylinder and the opposite surface of the other cylinder, and a play e2 between the slopes of two adjacent protrusions wherein e1 and e2 are determined in the direction transverse to the direction of paper advance in such a manner that the ratio of e1/e2 is between 0.8 and 1.
