摘要:
Die Erfindung betrifft ein Transfer- oder Schuhpressenband mit einer für die Auflage einer Papier- oder Filzbahn bestimmten Papierseite (1) und einer von der Papierseite abgewandten Maschinenseite (2), und mit einem Träger (3) und einer papierseitig und/oder maschinenseitig des Trägers (3) angeordneten strukturierten Deckschicht (4), die aus einem wenigstens ein Polymer, insbesondere Polyharnstoff und/oder Polyurethan umfassenden oder hieraus bestehenden Beschichtungsmaterial besteht und die sich zumindest an ihrer von dem Träger (3) abgewandten Seite durch eine strukturierte Oberfläche mit einer Vielzahl von Erhebungen (5) und Vertiefungen (6) auszeichnet und an ihrer von dem Träger (3) abgewandten Seite geschliffen ist. Darüber hinaus betrifft die Erfindung ein Verfahren zur Herstellung eines Transfer- oder Schuhpressenbandes sowie die Verwendung eines solchen als Pressenband, insbesondere Transfer- oder Schuhpressenband, in einer Papiermaschine.
摘要:
The present invention relates to belts useful in the manufacture of paper products, such as tissue paper. Particularly this invention relates to a belt used in a through-air drying process for making tissue products, and more particularly to an additively manufactured belt having a particular pattern thereon which imparts properties to tissue products manufactured therewith.

The present invention relates to the creation of toweling with surprisingly high absorbency using a furnish comprising a major proportion of recycle furnish when the furnish is creped from a Yankee dryer coated with a creping adhesive comprising polyvinyl alcohol and an epichlorohydrin crosslinked polyamide creping adhesive at a consistency corresponding to a sheet temperature (immediately prior to the creping blade) of between 225°F and 255°F (107°C and 124°C) , preferably ranging from about 230°F (110°C) up to about 250°F (121°C).
摘要:
A papermaking belt including zones of material laid down successively using a 3D printing process. The zones include at least a pocket zone configured to form three dimensional structures in a paper web by applying vacuum to pull the paper web against the pocket zone. In at least one exemplary embodiment, the zone also include at least one vacuum breaking zone configured to limit an amount of paper fibers pulled through the pocket zone by the applied vacuum.

A papermaking belt can have a reinforcing element with a surface and a plurality of discrete knuckles extending from portions of the surface. The plurality of discrete knuckles can be arranged in a pattern of repeat units, and each of the discrete knuckles within the repeat unit can have substantially the same shape and size. At least some of the discrete knuckles can be arranged in a plurality of rows of adjacent knuckles separated by a distance, including at least a first row and a second row. The distance between at least two adjacent discrete knuckles in the first row can be different than the distance between at least two adjacent discrete knuckles in the second row.
摘要:
A method for making a multiply fibrous structure. The method comprising the steps of: depositing a slurry of pulp fibers onto a Fourdrinier wire running at a first velocity V 1 ; transferring the web from the Fourdrinier wire to at least a first molding member moving at a second velocity, V 2 , slower than the first velocity, V 1 . The molding member comprises a substantially continuous relatively low density network at least partially defining a plurality of relatively high density, irregularly shaped, discrete elements situated in an irregular pattern. The embryonic web is partially dried, adhered to a Yankee dryer surface, creped from Yankee dryer and reeled at a velocity, V 4, that is faster than that (V 3 ) of the Yankee dryer.
