摘要： Press device for treating a material web that may includes an impermeable press element having a press face, an opposing element, and a nip formed between the press element and the opposing element. The press device may also include a felt belt that guides the material web through the nip and that is positioned between the material web and the opposing element. The material web may be separated from the press element after leaving the nip because the press element may further include at least one of grooves and holes formed in the press face that close in the nip due to pressing forces to form a smooth surface, and that open after leaving the nip.

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.
