摘要： 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.

摘要： A sheet forming unit including a headbox with at least one feed device, a turbulence generating device having a plurality of turbulence generating channels and a nozzle. The nozzle includes an outlet gap located downstream from the headbox forming a line of impingement in a flow direction. Immediately upstream from the nozzle is the turbulence generating device in which during operation of the headbox a fibrous stock suspension passes through the plurality of turbulence generating channels in partial flows. Inside a turbulence generating channel there is a final fluidization region in which a pressure loss is produced in the partial flow of fibrous stock suspension in the turbulence generating channel. The headbox and the forming unit are arranged so that a dwell time of the fibrous stock suspension from the final fluidization region to the line of impingement on the clothing is ≧30 ms to ≦300 ms.

摘要： A headbox includes a feed device feeding the fibrous material suspension, a nozzle, and a turbulence-generating device. The fibrous material suspension is guided in the turbulence-generating device in sub-flows through turbulence-generating channels. Within the individual turbulence-generating channel of the turbulence-generating device, at least one region forming a fluidization region is provided, in which a pressure loss can be generated in the sub-flow of the fibrous material suspension guided through said region. The nozzle and the turbulence-generating device are designed and dimensioned such that they are suitable for setting a dwell time of ≦200 ms of the fibrous material suspension flowing through the same from a final fluidization region of an individual turbulence-generating channel before inlet into the nozzle as far as the outlet gap of the nozzle, and a pressure loss of ≧50 mbar in the final fluidization region upstream of the inlet into the nozzle.

摘要： A headbox apparatus for a papermaking machine is disclosed. The headbox apparatus defines a flow path for stock flowing between an upstream location and a downstream slice lip. The apparatus includes a plurality of blocks which are anchored within the flow path between the upstream location and the slice lip. Each block and an adjacent block of the plurality of blocks define therebetween a flow tube for the flow therethrough of the stock. The flow tube has an upstream portion having an upstream and a downstream end. The flow tube has a downstream portion having an upstream and a downstream extremity, the upstream extremity of the downstream portion extending from the downstream end of the upstream portion. The downstream portion of the flow tube has a volume which is greater than a further volume of the upstream portion of the flow tube such that when the stock flows from the upstream portion to the downstream portion of the flow tube, the stock is mixed within the downstream portion.
