| 20080251227 | TISSUE MACHINE - An apparatus for producing a fibrous web, in particular a tissue web, with a press zone through which the fibrous web is passed in a lying position between a circulating permeable structured belt and a circulating permeable non-structured supporting belt. A press nip is provided on a Yankee Cylinder through which the fibrous web is passed in the lying position together with the structured belt between the structured belt and the Yankee cylinder, whereby the press zone is limited on the side adjacent the supporting belt by a substantially smooth surface, and whereby the supporting belt is not brought together with the fibrous web and the structured belt until proximate to the press zone. | 10-16-2008 |
| 20080257513 | APPARATUS AND METHOD FOR TREATING A FIBROUS WEB, IN PARTICULAR FOR PRODUCING A TISSUE PAPER WEB - The present invention provides an apparatus the surface of the web supporting face and/or the material forming the web supporting face are selected with a view to little crêping belt wear caused by operation of the apparatus, in particular with a view to a small coefficient of friction. | 10-23-2008 |
| 20080257514 | APPARATUS AND METHOD FOR TREATING A FIBROUS WEB, IN PARTICULAR FOR PRODUCING A TISSUE PAPER WEB - Apparatus for treating a fibrous web, in particular for producing a tissue paper web, with at least one crêping nip which is limited on the one side by a crêping belt and on the other side by a web supporting face formed in particular by a mating roll and through which the fibrous web can be passed, whereby a relative speed is provided between the crêping belt and the web supporting face, whereby in order to achieve a good crêping effect with simultaneous little crêping belt wear the material and/or the structure of the web supporting face and the surface of the crêping belt are coordinated with each other with a view to reducing the crêping belt wear caused by operation of the apparatus. | 10-23-2008 |
| 20090205794 | METHOD FOR THE PRODUCTION OF TISSUE PAPER - A method for the production of a tissue paper web, which is produced from a pulp suspension comprised of fibers, the pulp suspension having a refining degree of less than 21°SR and being of such condition that it is possible to produce from said pulp suspension a laboratory sheet according to TAPPI 205 SP 95 (Rapid Köthen) whose breaking length measured according to TAPPI 220 and TAPPI 494 at least a specific refining degree (RD | 08-20-2009 |
| 20090242158 | PROCESS AND APPARATUS FOR PRODUCING A TISSUE WEB - An apparatus for producing a fibrous web includes: a circulating permeable structured belt defining a sheet forming zone in which the fibrous web is formed; a circulating unstructured permeable supporting belt; a pressing section through which the fibrous web is led lying between the circulating permeable structured belt and the circulating unstructured permeable supporting belt; a Yankee cylinder having a surface and defining a press nip and a press nip region, wherein the fibrous web is led together with the structured belt through said press nip, the fibrous web in the region of the press nip being transferred from the structured belt to the surface of the Yankee cylinder; at least one doctor which doctors off the surface of the Yankee cylinder continuously; and a coating device which recoats the surface of the Yankee cylinder so that a renewed coating material is always present in the press nip. | 10-01-2009 |
