A device and a method for producing a pulp web in which the first clothing and the second clothing are wrapped partly round the forming roll and another roll. The pulp web formed is guided between the forming roll and the other roll on the first clothing and the second clothing is guided separately from the first clothing, at least in one section. This enables the pulp web to be produced with low energy consumption and operating costs.

Device and method for producing a fibrous web

The invention relates to a method and a device for drying a pulp web, with dewatering of the pulp web by pressing and the pulp web being guided directly on the press belt to a first transfer area for transfer of the pulp web to a transfer clothing and transfer of the pulp web in a second transfer area to a dryer. It is characterized in that the pulp web undergoes thermal drying between the first transfer area and the second transfer area. This enables production of a pulp web with improved quality characteristics and low energy consumption at the same time.

Device and method for producing a pulp web

A method for producing a fibrous material web, particularly for producing a tissue or hygienic paper web, in which a fibrous suspension is dewatered in a crescent former to obtain a fibrous material web, and dried on a Yankee. After the crescent former, the fibrous material web is guided along with the forming screen and felt over a suction roller downstream of the forming roller. A device for carrying out the method for producing a fibrous material web.

Method for producing a fibrous material web

A method for producing a fibrous pulp web, in which a fibrous pulp suspension is dewatered in a Twin Wire Former to form a fibrous pulp web which is dried with a TAD dryer. A pre-dewatering device with a hood and suction roll is provided after the Twin Wire Former and before the TAD dryer. The fibrous pulp web is guided through the pre-dewatering device between exactly two machine cloths. The machine cloth between suction roll and the web is a porous felt, and the machine cloth between web and hood is a structured wire. A volume flux of hot drying fluid greater than 100 m/(m&#xb7;min), preferably greater than 250 m/(m&#xb7;min,) is drawn through the fibrous pulp web into the suction roll.

Process for production of a fibrous pulp web

A process and a device for utilization of waste heat from a high-temperature hood in the dryer section of a paper machine. The waste heat from the high-temperature hood is applied to the waste steam and the condensate, respectively, from a steam system by means of a heat exchanger, thus improving utilization of the energy contained in the exhaust air from a high temperature hood.

Utilization of waste heat in the dryer section of paper machines

A device for removing dust from a moving paper web, where the dust is carried in a boundary layer of air that runs with the web, includes a first separating box mounted across the web running direction. The first separating box has a collecting duct extending across the web running direction, a curved guide surface which guides the paper web, and apparatus for deflecting the dust-laden air boundary layer into the collecting duct.
