摘要： In a headbox system for a papermaking machine with an adjustable distribution of the fiber stock suspension or pulp over the web width, the flow in the delivery slice is controlled in such a way that, across the web width, also the distribution of the fibers in respect of fiber orientation and quantity has a desired profile. For this purpose, the flow of the fiber stock suspension is controlled such that in the event of a change in the distribution of the fiber stock suspension across the web width, the horizontal component of the flow direction in the delivery slice remains, at all locations, always in the predetermined machine direction and thus transverse flows are avoided and the flow rate in the delivery slice has a predeterminate profile.

摘要： A longitudinal wire papermaking machine is disclosed wherein the longitudinal wire is guided in a dewatering region, following a pre-dewatering path, out of a wire plane downwardly over a deflection element and then upwardly over a downwardly domed or arched dewatering element towards the wire plane. The deflection element is arranged at a spacing K=approximately 15 to 80 mm from the dewatering element. The longitudinal wire is guided at the inlet section of the dewatering region, located between its outbound or run-off location at the deflection element and its lowest deflection location, over a negative pressure zone, for instance constituted by a suction chamber, which is effective at its underside. Hence, at the inlet section there is obtained a reduction in the suspension pressure and the fiber stock suspension is guided with an approximately constant total thickness lower into the dewatering region, i.e. at a relatively flat angle towards the dewatering element, so that there is avoided any backflow at the surface region of the suspension.

摘要： A dewatering apparatus contains a longitudinal wire and an additional wire which is guided, conjointly with the longitudinal wire, along a section of such longitudinal wire over a domed or arched surface. This domed or arched surface is formed, for instance, by the jacket or outer surface of a dewatering cylinder arranged within the wire loop of the longitudinal wire. The longitudinal wire is provided with a headbox and extends forwardly and after the dewatering apparatus essentially in a wire plane, above which upwardly rises the domed surface. Both of the wires are guided out of the wire plane over a dewatering shoe arranged within the wire loop of the additional wire towards the domed surface and from such--if desired over a deflection roll arranged beneath the wire plane--again towards the wire plane, where both wires separate from one another. Due to this arrangement there is realized a guiding of both wires which improves the dewatering action and is extensively independent of the elevational position of the wire plane, and at the same time affords a constructional simplification of the papermaking machine.

摘要： In a wet press for dewatering a web of material, for instance a web of paper, a contact pressure device presses against a rotating roll and exerts a pressure which increases in the travel direction of the web of paper. For this purpose, several rows of contact pressure elements are arranged sequentially in the travel direction of the web of paper. In each row the contact pressure elements are arranged side by side transversely to the travel direction of the web of paper. In order to circumvent a differential dewatering at the location of the contact pressure elements and at the gaps between the contact pressure elements of a row, the contact pressure elements of successive rows are shifted or staggered in relation to one another transversely to the web of material such that they mutually overlap. This prevents the arisal of strips in the paper being processed.

摘要： Calendering takes place in a calendering zone which operates under pressure with application of temperature and moisture. The desired smoothness is achieved with a correspondingly long dwell time of the material web in a correspondingly long calendering zone in view of the speed of web travel. A web which is still wet is guided between parallel heatable surfaces which are arranged on both sides of the web and face each other through the web and can each be pressed against the web. The surfaces are designed to form and hold a given precise contour of the calendering zone over its full length. One surface is constructed e.g. as a casing of a heated roller and the second surface is constructed as an endless flexible belt which can be pressed in a direction towards the roller casing by means of a concave supporting element. If wished, the web can be calendered on both sides with the method.

摘要： A headbox contains a rigid lower lip which is directed towards a dewatering surface, a wire or the like, guided over a rotating cylinder or roll, and a rigid upper lip having a rigid lip portion which, in conjunction with a portion or section of the dewatering surface neighboring the lower lip downstream with respect to the flow of the stock suspension, delimits a sheet forming chamber or space. The lip portion is provided at the region of the sheet forming chamber with step or groove-like depressions or recesses extending transversely with respect to the direction of flow of the stock or fiber suspension. These recesses serve to form recirculation turbulence which supports the marginal flow of the stock suspension. With this arrangement the effect of the wall friction upon the flow velocity is practically eliminated, so that with a flow velocity of the stock suspension which is adjusted in accordance with the travel speed of the dewatering surface, there is ensured for a uniform forming of the suspended fibers of the stock suspension in the lengthwise and transverse direction of the paper which is to be fabricated.
摘要翻译：流浆箱包含一个刚性的下唇，该下唇指向一个脱水表面，一根线或类似物，被引导到一个旋转的圆筒或滚筒上，刚性的上唇具有一个刚性的唇缘部分，该刚性唇缘部分与相对于原料悬浮液的流动在下游相邻的下唇的脱水表面限定了片材形成室或空间。唇形部分设置在片材形成室的区域，其具有相对于原料或纤维悬浮液的流动方向横向延伸的台阶或槽状凹陷或凹陷。这些凹槽用于形成支持浆料悬浮液的边际流动的再循环湍流。通过这种布置，实际上消除了壁摩擦对流速的影响，使得随着根据脱水表面的行进速度调节的原料悬浮液的流速，确保了均匀地形成在要制造的纸张的长度方向和横向方向上的悬浮纤维悬浮纤维。

摘要： The invention relates to a method for roll cooling in paper machines with soft smoothing mechanisms. The object of the invention is to protect the soft roll from damage without having to increase the extent of edge trimming of the paper web. This is achieved in that the parts of the soft roll which respectively project beyond the width of the paper web are cooled by the application of a thin and sharply bounded water film. The corresponding devices for generating the water films are mounted in carriages which are displaceable along a transverse beam parallel to the roll.

摘要： A twin screen paper forming apparatus is provided having upper and lower screens moving in a first direction and wrapping around a portion of a leading forming roller positioned at the beginning of a forming zone where the upper and lower screens converge to form a twin screen. At least one stationary forming element is positioned downstream of the leading forming roller to contact with the lower screen. A water guide element is also located in the region of the forming zone approximately at the start of the forming zone. At least one forming rail contacts the upper screen and a pulp suspension discharge nozzle is positioned, to prevent preliminary draining, upstream of the location where the upper and lower screens converge.
