Abstract: The front wall and support arrangement is shaped as a stiff support structure extending across the entire machine width above a slice chamber. The support structure is deformed due to its inherent weight and because of the pressures and temperatures prevailing in the slice chamber. To counteract these deformation effects the support structure is supported by a support carrier of about the same length as the support structure. To attain a substantially lower structural height, the support carrier is arranged relative to the support structure such that an intermediate space prevails between the lower wall of the support structure and the support carrier. This intermediate space accommodates force-generating support elements. Each of the force-generating support elements is provided for only a portion of the surface or area to be supported in the intermediate space. In a preferred embodiment the support structure is a box-like girder equipped with an upright positioned I-profile constituting the support carrier and arranged within the interior space of the box-like girder. Advantageously, the support elements are elastic tubes closed at both ends and extending substantially parallel to the longitudinal axis of the front wall, and the individual elastic tubes are each connected to at least one pressure source.

Abstract translation: 前壁和支撑装置被成形为在切片室上方跨越整个机器宽度延伸的刚性支撑结构。 支撑结构由于其固有的重量而变形，并且由于在切片室中的压力和温度而变形。 为了抵消这些变形效应，支撑结构由与支撑结构大致相同长度的支撑载体支撑。 为了获得基本上较低的结构高度，支撑载体相对于支撑结构布置，使得在支撑结构的下壁和支撑托架之间存在中间空间。 该中间空间容纳力产生支撑元件。 每个力产生支撑元件仅提供在中间空间中待支撑的表面或区域的一部分。 在优选实施例中，支撑结构是配备有构成支撑托架的直立定位的I型轮廓并且布置在箱状梁的内部空间内的箱状梁。 有利地，支撑元件是在两端封闭并且基本上平行于前壁的纵向轴线延伸的弹性管，并且各个弹性管各自连接到至少一个压力源。

Abstract: A wet end of a paper-making machine, including a headbox with a chamber and a discharge nozzle. A turbulence generator is connected with the headbox and includes a plurality of fluid passages disposed substantially parallel to each other. Each fluid passage is in fluid communication with the headbox chamber and has an inlet. All of the inlets conjunctively define a fluid inlet area. A fiber stock delivery device includes at least one outlet, with all of the outlets conjunctively defining a fluid discharge area. Each outlet is configured to discharge the fiber stock in a direction substantially parallel to the fluid passages in the turbulence generator. The fluid discharge area of the fiber stock delivery device is smaller than the fluid inlet area of the turbulence generator. A hydraulic increaser interconnects the fluid discharge area of the fiber stock delivery device with the fluid inlet area of the turbulence generator. The hydraulic increaser includes at least two interior abutting surfaces, with each abutting surface having at least one end defining an adjoining edge with another said abutting surface. Each abutting surface defines a line at each end which is disposed tangent to the abutting surface at the respective end. Each tangent line defines an acute angle with a tangent line of an adjacent abutting surface which is between approximately 1.degree. and 10.degree. preferably not greater than approximately 4.degree..

Abstract: The invention is directed to a guide connectable to a paper roll in a paper machine for moving an end of the roll in a direction transverse to a longitudinal axis of the roll. The guide includes a roll mounting frame connectable to the roll, a support frame, and at least one elongate member interconnecting the support frame with the roll mounting frame. The at least one elongate member is elastically deformable in the transverse direction and thereby allows movement of the roll mounting frame relative to the support frame in the transverse direction. A positioning device is engaged with the roll mounting frame for moving the roll mounting frame in the transverse direction and maintaining the roll mounting frame in one of a plurality of positions relative to the support frame.

Abstract: A headbox for a paper machine, with a main chamber through the lower part of which flows fiber suspension in the longitudinal machine direction. The main chamber has on the upstream end a first perforated roll and a machine-wide feed channel as well as on the downstream end a second perforated roll and a machine-wide nozzle type outlet channel. Provided between the perforated rolls is a vertical partition which is vertically adjustable, creating between the bottom of the main chamber and the partition a machine-wide channel section which is variable in its height. The downstream outside surface of the partition has a convex shape, in a fashion such that the clearance of the channel section increases in the direction of flow.
