A machine for the production of a fibrous web. The fibrous web being a paper web, a cardboard web or a tissue web. The machine including a hot air hood, an upstream drying zone, a downstream dryer cylinder and a dryer hood. The upstream drying zone has an area in which the moving fibrous web is treated with hot air from the hot air hood, the hot air hood being allocated to the upstream drying zone. The downstream dryer cylinder is a Yankee-Cylinder. The dryer hood is associated with the downstream dryer cylinder for further drying of the fibrous web. The hot air for the hot air hood is at least partially recovered from the dryer hood which is associated to the downstream drying cylinder.

Method and apparatus for drying a fibrous web

A method for drying a fibrous web, particularly a paper, cardboard or tissue web whereby the moving fibrous web is treated with got air in the area of a pre-definable drying zone the fibrous web is treated, at least in some areas inside the drying zone with steam.

A method for drying a fibrous web, especially a paper, cardboard or tissue web, the moving web is treated with hot air from a hot air hood in the area of a upstream pre-defined drying zone, and is subsequent carried to the drying zone in a downstream drying cylinder, especially a Yankee-Cylinder, to which an additional hood is allocated and in whose area the fibrous web is dried further. The hot air for the hot air hood allocated to the upstream drying zone is recovered, at least partially, from the exhaust air of the hood allocated to the downstream drying cylinder.

Method for drying a fibrous web

Apparatus for producing a fibrous web that includes a smooth roll and at least one opposing element. The smooth roll and the at least one opposing element are arranged to form at least one press nip, a felt is structured and arranged to guide the fibrous web through the at least one press nip, and an embossing belt is structured and arranged to receive the fibrous web from the smooth roll. The smooth roll and the embossing belt are arranged such that the fibrous web passes in an unsupported manner over a free draw between said smooth roll and said embossing belt.

Process and apparatus for producing a fibrous web

An apparatus to produce a fibrous web having a three-dimensional surface structure, especially a paper, cardboard or tissue web, includes a headbox, a forming element, especially a forming roll, a structured fabric and a dewatering fabric, whereby the structured fabric and the dewatering fabric run together and form a stock infeed nip and are carried over the forming element whereby the structured fabric is the inside fabric and the dewatering fabric is the outside fabric and whereby fibrous suspension is fed into the stock infeed nip by way of the headbox. At least one catch pan is provided in the area of the outfeed nip which is formed between the forming element and the structured fabric coming off it for water, fibers, fines and/or similar substances accumulating in the area of this outfeed nip.

Apparatus to produce a fibrous web

Dewatering system for dewatering a web. The system comprises a former, a belt press, and a structured fabric comprising a paper web facing side and being guided over a support surface and through the belt press. The structured fabric runs at a speed differential relative to a wire of the former. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
