    Abstract: 1,045,580. Forming pulp sheets. IMPROVED MACHINERY INC. Jan. 8, 1965 [Jan. 20,1964], No. 893/65. Heading D2A. [Also in Division B1] A cylinder mould for separating wood pulp from its filtrate and forming a pulp sheet comprises a drum portion 12, imperforate ribs 22 mounted thereon and extending in an axial direction to form compartments between adjacent ribs 22, cover elements 40 extending arcuately over the greater portion of each compartment but leaving a gap 42, means - for example a wire 44 of rectangular cross-section spirally wound about the drum - on elements 40 to form a plurality of peripherally extending grooves, and a sheet filter 50. Cover elements 40 are upturned at one end 48 which has notches through which wire 44 passes, end 48 dividing each groove into separate sections. In use the mould is rotatably mounted in a vat and has a stationarily mounted valve element 16, Fig. 1 (not shown) extending around the mould either at the middle or at one end. The compartments between ribs 22 have holes in the end adjacent element 16 to be in communication therewith. Over the greater arcuate portion of the mould, element 16 is connected to a source of suction through the centre of the mould so that suction is applied to the inside of screen 50, and over the remaining arcuate portion of the mould valve element 16 is connected to the atmosphere, so that the pulp can be removed from the mould.

    Abstract translation: 1,045,580。 形成纸浆。 改进机械有限公司1965年1月8日[1月 20,1964]，第893/65号。 标题D2A。 [也在B1部分]用于从其滤液中分离木浆并形成纸浆片的圆筒模具包括鼓部分12，安装在其上并在轴向方向上延伸的无孔肋条22，以在相邻肋条22之间形成隔间，覆盖元件40延伸 在每个隔室的大部分上弧形地，但留下间隙42，意味着例如围绕鼓螺旋地缠绕在元件40上的矩形横截面的线44，以形成多个周向延伸的凹槽和片状过滤器50。 盖元件40在一端48上翻转，端部48具有通过该导线44穿过的凹口，端部48将每个凹槽划分成单独的部分。 在使用中，模具可旋转地安装在大桶中，并且具有静止安装的阀元件16， 1（未示出）在模具的中间或一端延伸。 肋22之间的隔间在邻近元件16的端部具有与其连通的孔。 在模具的较大弓形部分上，元件16通过模具的中心连接到抽吸源，使得抽吸被施加到筛网50的内部，并且在模具阀元件16的剩余弧形部分上方连接 到大气中，使得纸浆可以从模具中去除。
