    • An improved multi-layer paper sheet forming system is disclosed, in which a degree of dispersion of fibers under the condition where a paper layer has been formed is large, thereby formation of a paper sheet is improved, moreover, bases of short wire cloth sections can be installed at the same level as a building floor and a complicated base of the shape of steps is not necessitated. The system comprises one endless felt loop and a plurality of short wire cloth sections disposed on the endless felt and provided with a dewatering instrument having, as dewatering elements, forming blades consisting of two zones, that is, a flat front half and a curved rear half. The short wire cloth section includes a forming roll having a large diameter and a breast roll having a small diameter, and the plurality of short wire cloth sections are disposed substantially at the same level. A movable return roll is equipped, which raises the felt between the adjacent short wire cloth sections so as to wrap around the short wire cloth so that an initial engagement point between the felt and the short wire cloth may come to an arbitrary position of the curved portion of the dewatering instrument existing at the upper portion of the short wire cloth section.
    • 公开了一种改进的多层纸张形成系统,其中在形成纸层的条件下纤维的分散程度大,从而改善了纸张的形成,此外,短的布线部分的基部 可以安装在与建筑物地板相同的水平上,并且不需要步骤形状的复杂的基础。 该系统包括一个环形毡环和多个布置在无端毛毡上的短布线部分,并且设置有脱水装置,该脱水装置具有作为脱水元件的成形刀片,该两个区域由两个区域组成,即平坦的前半部和弯曲的后部 半。 短丝布部分包括具有大直径的成形辊和具有小直径的母乳辊,并且多个短丝布部分基本上设置在相同的高度。 设置有可移动的返回辊,其使相邻短的布线部分之间的毛毯上升,以围绕短的布线缠绕,使得毛毡和短布线之间的初始接合点可以到达弯曲的任意位置 脱水装置的部分存在于短丝布部分的上部。

    • An estimation device estimates a hidden state of an estimation subject from an observable state in a manner of a time series. The observable state is observed from the hidden state of the estimation subject under a procedure that has a hierarchical structure, which includes the hidden state of the estimation subject, the observable state, and an intermediate hidden state therebetween. The estimation device includes an estimation subject hidden state predicting means, an intermediate hidden state predicting means based on the state transition structure of the hidden state of the estimation subject, an intermediate hidden state likelihood observing means, an intermediate hidden state estimating means, an estimation subject hidden state likelihood observing means, estimation subject hidden state estimating means, an intermediate hidden state predicting means based on the state transition structure of the intermediate hidden state, and the mixing means.

    • In order to prevent the lowering of yield of fibers of stock which is pinched by two wires and being transferred, specific dewatering blades are disposed on each of the wires are used. Blade sets are disposed on two wires 1, 2 forming loops to pinch stock 7 and running therealong. The blades of one blade set are dewatering limiting blades 20, each having a plane portion 20a to support the wires 1, 2 and an inclined face 20b disposed on the wire entering side of said plane portion 20a and forming a space of a wedge shape facing the wire face and enlarging toward the upstream side in the wire running direction. The blades of the other blade set are dewatering blades 21, each having a plane portion 21a to support the wires 1, 2 and an edge 21b to scrape water toward the upstream side of said plane portion 21a. The plane portion 21a having the edge 21b is disposed opposite to the space of a wedge shape.
    • 为了防止由两根线夹住并被转移的原料的纤维的收率降低,使用每根导线上的特定的脱水叶片。 刀片组被布置在两条线1,2上,形成环以夹紧坯料7并在其上运行。 一个叶片组的叶片是脱水限制叶片20,每个叶片具有平面部分20a以支撑线1,2,以及设置在所述平面部分20a的进入侧的线的倾斜面20b,并形成面向 导线面向导线方向上游侧扩大。 另一个叶片组的叶片是脱水叶片21,每个叶片具有平面部分21a,以支撑线材1,2和边缘21b,以向所述平面部分21a的上游侧刮水。 具有边缘21b的平面部分21a与楔形的空间相对地设置。

    • A twin wire former of a paper machine can perform dewatering gently and symmetrically on the front and back sides of the wet paper, thereby producing paper with good yield and excellent front/back similarity. The twin wire former includes the loops of two wires, and first, second and third dewaterers, having large radii of curvature and disposed inside one and the other of the loops of the wires sequentially alternately between a point where a raw material jet alights on the wires and a couch roll, and the wire-run over this section is diagonal. The first and third dewaterers are disposed inside the loop of the wire and the second dewaterer is disposed inside the loop of the wire. This second dewaterer is pivotable about a point in the vicinity of its rear end, and the couch roll is a solid roll. This couch roll, a transfer suction box and the third dewaterer are mounted on a swing arm and can be pivoted for wire installation.
