    摘要： The invention relates to a headbox (1) for a machine for producing a fibrous web (3), in particular a paper or cardboard web, from at least one fibrous stock suspension (2), having a feed apparatus (4) which feeds the at least one fibrous stock suspension (2), having a distributor-pipe perforated plate (6) which is adjacent downstream and has a multiplicity of channels (7) which are arranged in rows (Z) and in columns (S), having an intermediate channel (8) which lies downstream of the latter, extends over the width (B) of the headbox (1) and has a plurality of means (9, 9.1) which are spaced apart from one another in the width direction (B) of the headbox (1) for the preferably regulatable/controllable metering of a fluid (10) in fluid part streams (10.T) into the at least one fibrous stock suspension (2). The headbox according to the invention is characterized in that the means (9, 9.1) for the preferably regulatable/controllable metering of the fluid (10) in fluid part streams (10.T) into the at least one fibrous stock suspension (2) is also configured for the preferably regulatable/controllable metering of at least one further fluid (19; 19, 24) in fluid part streams (19.T; 19.T, 24.T) into the at least one fibrous stock suspension (2), wherein the individual means (9, 9.1) comprises in each case a plurality of metering channels (20; 20, 25) for the at least one further fluid (19; 19, 24), which metering channels (20; 20, 25) have a respective metering-channel opening (20.1; 20.1, 25.1), open at different heights and are connected to a common supply channel (21; 21, 26).

    摘要翻译： 本发明涉及一种用于机器的流浆箱（1），该流浆箱用于由至少一个纤维材料悬浮液（2）生产纤维幅材（3），特别是纸幅或纸板幅材，具有供给装置（4） 至少一个纤维材料悬浮体（2），其具有分配管多孔板（6），所述分配管多孔板邻近下游并且具有多个布置成行（Z）和列（S）的通道（7），其具有 位于所述中间通道（8）下游的中间通道（8）在所述流浆箱（1）的宽度（B）上延伸并且具有多个在宽度方向（B）上彼此间隔开的装置（9,9.1） 用于流体部分流（10.T）中的流体（10）优选可调节/可控地计量加入至少一个纤维材料悬浮液（2）中的流浆箱（1）。 根据本发明的流浆箱的特征在于，用于流体部分流（10.T）中的流体（10）优选可调节/可控地计量到至少一个纤维材料悬浮液（2）中的装置（9,9.1） 还构造成用于将流体部分流（19.T; 19.T，24.T）中的至少一个另外的流体（19; 19,24）优选地调节/可控地计量加入到所述至少一个纤维原料悬浮液 ），其中各个装置（9,9.1）分别包括用于所述至少一个另外的流体（19; 19,24）的多个计量通道（20; 20,25），所述计量通道（20; 25）具有相应的计量通道开口（20.1; 20.1,25.1），所述计量通道开口（20.1; 20.1,25.1）在不同高度打开并连接到公共供应通道（21; 21,26）。

    摘要： The invention relates to a headbox (1) for a machine for producing a fibrous material web, in particular a paper or cardboard web, comprising a central assembly (2) preferably forming the carrier elements (5, 6) of a turbulence generator (7), said assembly having a table leaf (3) on the bottom side, and further comprising a headbox nozzle (10) adjoining directly downstream in the machine running direction (L) and extending in the machine transverse direction (Q), said nozzle comprising at least one lower and one upper continuous nozzle wall (11, 12) extending over the machine width (B). The headbox (1) according to the invention is characterized in that the lower nozzle wall (11) of the headbox nozzle (10) comprises a lower lip plate (14), in particular a lower lip carrier plate (14.1), which is connected, in particular welded, to the table leaf (3) of the central assembly (2) by means of a plurality of ribs (29) extending in the machine running direction (L) and spaced apart in the machine transverse direction (Q). The ribs (29) are designed in an elastic or pliable manner in the machine transverse direction (Q).
