摘要： The invention relates to a headbox for a machine for producing a fibrous web, especially a paper or cardboard web, from at least one fiber suspension, comprising a feed device feeding the at least one fiber suspension, a perforated distribution pipe plate arranged immediately downstream thereof and having a plurality of channels arranged in lines and columns, an intermediate channel arranged downstream thereof, extending over the width of the headbox and having a plurality of means for dosing a fluid in partial fluid streams to the at least one fiber suspension in a preferably adjustable/controlled manner, the means being spaced apart from each other in the width direction of the headbox and the individual means comprising a plurality of dosing channels having respective dosing channel openings on the outlet side and a dosing channel length, arriving at different levels and being connected to a common supply channel. The headbox according to the invention is characterized in that the dosing channel length of the dosing channel is 1.5 times longer than the dosing channel opening of the dosing channel on the outlet side and in that the distance of the dosing channel opening of the dosing channel on the outlet side to the turbulence generator ranges from 0 to 50 mm.
摘要翻译：本发明涉及一种用于从至少一个纤维悬浮液生产纤维幅材，特别是纸或纸板幅材的机器的流浆箱，其包括供给至少一种纤维悬浮液的进料装置，紧邻其下游布置的穿孔分配管板并且具有以行和列布置的多个通道，布置在其下游的中间通道，其在所述流浆箱的宽度上延伸并且具有多个用于将部分流体流中的流体计量给所述至少一个纤维悬浮液的装置，优选地该装置在流浆箱的宽度方向上彼此间隔开，并且各个装置包括多个计量通道，其具有出口侧上的相应配量通道开口和达到不同水平的配量通道长度，连接到公共供应通道。根据本发明的流浆箱的特征在于，计量通道的计量通道长度比出口侧的计量通道的计量通道开口长1.5倍，并且计量通道的计量通道开口的距离湍流发生器的出口侧范围为0至50 mm。
