摘要： To regulate the basis weight cross section of the fiber suspension dispensed by the outlet of a headbox of a paper making machine onto the screen or screens of the following forming section, the headbox is sectioned across the width of the machine with individual first sections of fiber suspension across the width. The fiber suspension on the screen(s) in the following forming section is drained and the drained filtrate is collected in second sections respectively generally corresponding to the first sections of the headbox. The removed sectioned filtrate is recycled to the respective sections of the headbox and is mixed with the suspension normally entering the headbox to regulate and make more uniform the basis weight cross section of the fiber suspension.

摘要： In a papermaking machine, the drying section includes a vacuum based system which serves to guide the web and supporting felt (15) from a first drying cylinder (11) to a transfer vacuum roller (10), which has perforations (13) through which a vacuum is communicated into the interior of the roller 10 from of an external suction box (14). The suction box (14) includes lengthwise extending sealing strips (28, 29) located adjacent and bounding the free circumferential surface of the transfer roller (10), which is not overlapped by the felt of the drying section. The sealing strips extend from the suction box 14 to the roller mantel (10a) of the roller 10. These strips are further designed in the style of a doctor blade and are flexibly mounted on the suction box (14) so that they are flexible and biased against the roller 10 by spring action. They extend approximately tangentially to the surface of the roller mantel (10a), contacting it gently.

摘要： The twin-wire former serves for the production of a web of paper or board. Two wire belts (endless wire loops 11 and 12) form a twin-wire zone with each other. Within the twin-wire zone, the one wire belt (12) travels over rigid ledges (28', 28) which are arranged spaced apart from each other on a water-removal box (18). Within the twin-wire zone, furthermore, the other wire belt (11) travels over several ledges (27) which lie opposite the rigid ledges (28), are supported by means of resilient elements (springs 24, pneumatic pressure cushions, or the like), and can be pressed with a selectable force against the other wire belt. Within one of the wire loops (for instance 11), bridging at least two of the ledges (27) present there, a closed wire support surface (9) is provided. A secondary headbox (10') can be arranged in front of the closed wire support surface (9).

摘要： A method for optimizing the efficiency of a set of machines comprising a double-controlled turbine and a generator. A correlation is determined between the efficiency .beta., flow Q, variable height of fall H, gate opening .DELTA..gamma. and runner opening .phi. on a model set of machines by test series. The determination yields a model optimum curve for the respective height of fall, the model optimum curve having the optimum gate opening as a function of flow and runner opening. An optimum efficiency for an operating point of a large-scale system is determined by, based on the model optimum curve, making variations of the gate opening .DELTA..gamma. and of the runner opening .phi. on the large-scale system, the variations being such that the flow of the model set of machines would remain constant for the same variations, and wherein the flow of the large-scale system is also presumed to be constant. The power outputs before and after the variations are compared to determine stepwise the .DELTA..gamma./.phi. operating point with optimum efficiency.

摘要： A dryer section for a machine for drying a fibrous web and particularly a paper web. The dryer section comprises a row of dryer cylinders which alternate with reversal suction rolls along the path of the web. The dryer cylinders are separated into at least an upstream first dryer part and a downstream second dryer part in the path of the web through the dryer section. A continuous supporting belt travels along with the web alternately over each dryer cylinder and its associated suction roll in respective dryer groups in each of the upstream and downstream dryer parts. Every suction roll in the upstream first part has a stationary suction box in it. Every suction roll in the downstream second part does not have a suction box. All of the suction rolls have a perforated roll shell. The density of the perforations in the roll shell of the suction rolls in the first upstream part is at least twice as great as the density of the perforations in the roll shell of the suction rolls in the second downstream part. The first suction rolls have a smaller diameter than the second suction rolls.

摘要： The dry end of a paper making machine includes a twin wire dryer group following a single wire dryer group. The paper web is continuously guided by a support belt which moves alternately between dryer cylinders and intermediate deflecting rolls in the single wire dryer group. In the twin wire dryer group, the web travels over open lengths between dryer cylinders in the two rows of the second group. A rope guide threads the web into the twin wire dryer group. The start of the rope guide, called the rope shears, is in the vicinity of the periphery of the last or next to last deflecting roll called the selected deflecting roll in the single wire dryer group. Between the selected deflecting roll at the start of the rope shears and the preceding selected dryer cylinder, there is a relatively long straight path of travel for the support belt. Parallel to that path, there is a scraper and a guide plate which deflects the edge strip of the web laterally into the rope shears which is laterally to the side of the web. The rope guide then threads the web into the second dryer group.
