摘要： A twin-wire former for the production of a web of paper from a fiber suspension. An upper endless loop of wire belt having a lower horizontal run and a lower endless loop wire belt having an upper horizontal run. Guide rolls support the wire belts to define a twin-wire zone. The upstream inlet wedge of the twin-wire zone is disposed at the outlet from a head box. The initial part of the path of the twin-wire zone has a gradual curvature convexly with respect to the lower wire belt, and in that initial portion are positioned guide tables, suction boxes and dewatering elements. This curved initial part is followed by a forming roll within the loop of the upper wire belt. The twin-wires wrap an arcuate sector of the lower region of the forming roll. A support roll follows the forming roll. The support roll is upraised sufficiently to wrap the twin-wires around the bottom of the forming roll and over an arcuate sector at the top of the support roll. Following the support roll, the upper wire separates from the lower wire. In the continuing generally horizontal, slightly descending path of the lower wire with the web on it are disposed a plurality of suction boxes and a lower wire suction roll to define a final dewatering path after the twin-wire zone.

摘要： A paper machine forming section with two wire forming units. One of the two forming units is a twin wire web forming unit having a headbox, two wire loops arranged in sandwich-like manner and a drainage element for each of the wire loops. The first web-forming unit has a first section including a curved suction drainage element or roll in the first lower wire loop; a second section with opposing drainage ledges, wherein the drainage ledges are stationary on the upper side and the drainage ledges are developed resiliently pressable on the bottom side; the drainage ledges of the upper and lower sides are arranged staggered with respect to each other in the direction of travel of the wire, and at least the ledges of the upper side are developed with suction; a third section which has at least one suction wire separating element on one side. The second web-forming unit is a hybrid former with a single wire. The guide rolls for the second wire of the first former and for the wire of the second former guide them on a joint wire path where the multilayer web is transferred to the wire of the second former. There is a headbox associated with the wire of the second former. A respective backwater circuit collects water and materials drained from each of the forming units and returns them to the respective headboxes.

摘要： In a twin-wire former for the production of a paper web, two wire belts (11 and 12) together form a twin-wire zone which is divided into three sections (I, II and III). In the first section (I) the two wires (11, 12) travel over a curved forming shoe (16). They form there a wedge-shaped inlet slot (15) with which a headbox (10) is directly associated. In the second section (II), several resiliently supported strips (27) rest against the lower wire (11) and between each of said strips (27) a rigidly mounted strip (28) rests against the upper wire (12). In the third section (III) both wire belts (11, 12) pass over another curved forming shoe (23).

摘要： A sorter for paper pulp suspension including a rotationally symmetrical wire cage and a rotor supporting a plurality of vanes for rotating about the interior of the cage for moving suspension through the wire cage, the vanes being non-uniformly spaced. An annular pulp chamber surrounds the screen for collecting the pulp. A suspension outlet at the bottom of the pulp chamber receives the pulp from the pulp chamber. The pulp chamber extends axially beyond the lower end of the wire cage. An annular damping chamber surrounds the lower end of the pulp chamber and flow from the pulp chamber to the pulp outlet is past the damping chamber. The damping chamber develops a pool of the suspension in it. A pressurized gas cushion above the pool of suspension in the damping chamber controls the level thereof and damps the motion of the pulp in the pulp chamber.

摘要： This device, preferably formed as a dual paper machine, has according to a preferred embodiment two endless screens, mainly a lower screen (21) and an upper screen (22). The lower screen (21), on which is formed a paper web, and the upper screen (22) are moved together in the lower part of a dehydration cylinder (25) arranged in the upper screen. Both screens (21,22) are unrolled from the rising lower quadrant of said cylinder (25) and are laid on the upper part of the support cylinder (26) arranged in the lower screen (21). The bandage of the dehydration cylinder (25) has hollows which absorb water from the screens along their arcs of contact with the cylinder and which project the water towards the inside of the loop formed by the screens of the cylinder. In the feed direction of the screens and downstream of the support cylinder (26), there is arranged a receiving container (36) for the projected water. The container has a curved covering wall (40) which extends opposite the feed direction of the screens up to the interstice formed between the dehydration cylinder (25) and the screens (21,22). The reception container (36) is divided into two chambers (44,45) which extend transversally to the screens and which have separate side discharge conduits. The water supplied into the main chamber (45) through the covering wall (40) is deviated by means of blades (52) towards the direction of the discharge conduit.

摘要： A head box has a preferably fixed flow-carrying wall (11) and a movable flow-carrying wall (13) defining a nozzle-like stock conduit (14) and an outlet slot (15). The movable wall is provided with an adjustable profile bar (35) at the stock outlet slot. For coarse adjustment of the slot width, two lifting devices (21) act on the movable flow-carrying wall. Fine adjustment of the slot width is performed by adjustment spindles (36) acting on the profile bar.To improve adjustment of the stock outlet slot by the movable wall and to use the profile bar adjustment to perform very small corrections to the slot width, a front end section (24) of the movable wall located in the region of the stock outlet slot is flexibly constructed with respect to the remaining part of the wall, and a plurality of adjustment units (33) are spaced across the machine width and act on the flexible end section directly in front of the stock outlet slot.Thereby the movable wall (33) can be adapted with relatively high accuracy to the contour of the fixed wall (11) on the outlet slot side by the adjustment units (33) acting on the flexible end section (24). The immersion depth of the profile bar (35) into the stock conduit is therefore largely constant over the machine width. Cross currents and variable velocities of the stock flow are avoided and the paper's properties are improved.
摘要翻译： 头箱具有优选地固定的流动支承壁（11）和限定喷嘴状储存管道（14）和出口槽（15）的可移动流动支承壁（13）。 可移动壁在库存出口槽处设置有可调节型材（35）。 对于槽宽度的粗调，两个提升装置（21）作用在可动流动壁上。 狭缝宽度的微调是通过作用在轮廓杆上的调节主轴（36）进行的。 为了通过可移动壁改善库存出口槽的调节并且使用型材条调节对狭槽宽度执行非常小的校正，位于库存出口槽区域中的可移动壁的前端部分（24）是 相对于壁的剩余部分灵活地构造，并且多个调节单元（33）跨越机器宽度间隔开，并且直接在坯料出口狭槽的前面作用在柔性端部上。 因此，通过作用在柔性端部（24）上的调节单元（33），可移动壁（33）可以相对于出口槽侧的固定壁（11）的轮廓具有相对较高的精度。 因此，型材棒（35）浸入料斗导管中的浸入深度在机器宽度上基本保持不变。 避免了流动的交叉电流和可变速度，改善了纸张的性能。
