process for the manufacture of paper, kar tonnes or other equivalent non-woven products, elasticity and / or a high wrijvingscoefficient.

摘要

A method of manufacturing paper, cardboard, or another equivalent fiber web having a certain stretchability and/or a high coefficient of friction includes the steps of shortening or upsetting a paper web just prior to conveying the latter to a press section while adhering the web at the press section to a fabric in the form of a suitable felt or wire which is common to successive press nips of the press section for conveying the web to the successive press nips, these press nips including first and second press nips where the web is engaged by an additional endless fabric structure in the form of suitable felt or wire so that at least at the first and second press nips the web is sandwiched between a pair of fabrics, with this additional fabric structure being spaced from the part of the web which travels from the first to the second press nip. Subsequent to at least one of the first or second press nips the additional fabric which engages the web is dried before returning to its engagement with the web so as to remove therefrom water which has been transferred thereto from the web.
