Abstract: The dryer section in a papermaking machine has a single tier of all top felted dryer rolls (24) six to nine feet in diameter. Air caps (42) are employed over the dryer rolls (24) to simultaneously dry both sides of the web (28) to prevent curl and to increase drying rates. The air caps (42) employ blown air at a temperature of 250-900 degrees Fahrenheit and air speeds of 8000-40000 feet per minute. The dryer fabric (32) employed is foraminous with a permability of between 300-1200 cubic feet per minute per square foot and is designed to withstand peak temperatures of up to 900 degrees Fahrenheit and average temperatures of between 500-600 degrees Fahrenheit. A single transfer roll (150), or more advantageously, two grooved vacuum rolls (50) in a vacuum box (54) are disposed between the dryer rolls to maximize the circumferential wrap of the web and, at the same time, support and transport the web between dryer rolls.

Abstract: A plurality of like wedge bars (36) are formed with a groove (46) between two lands (48). The wedge bars (36) are assembled into a cylindrical screen (24), with the grooves (46) defining screening slots (30) of a uniform width. The wedge bars (36) may be electron beam welded or furnace brazed to support rings (44). Alternatively, the wedge bars (36) may be held in place by slots in support rings (44) and circumferential clamping applied by jack wedge assemblies (58). Multiple cylindrical segments (123) may be connected together into a single screen cylinder (24) by an ear (125) and slot (133) arrangement. The screen cylinder so formed may have slots (30) of 0.004 inches or less in width, and may be formed of a wide range of wear and corrosion resistant materials.

Abstract: A press section is provided for a papermaking machine having an Extended Nip press (28) before a conventional press section (30) such as a Beloit Corporation Tri-NipJ or TwinverJ press. A Beloit Corporation Extended Nip7 press or similar types press, preferably of the closed blanket type, is installed before an conventional two or three nip press and thus reduces the problem of the web sticking to the center roll (40) in the conventional press. The use of an Extended Nip press in front of a conventional pressing section can also increase the bulk of the web being formed. The pressing section of this invention is particularly useful for pressing webs formed of 100 percent tropical hardwood fibers which contain resinous particles which can cause problems in sticking to the center roll.

Abstract: An extended nip press (20) has a shoe (26) driven by two pistons (36, 38) to engage a blanket-supported web (33) against a crown controlled roll (24). Each ENP shoe piston (36, 38) is offset from the line of force application (60) of the crown control piston (48) by a moment arm distance (X, Y). A balancing of the hydraulic pressures in the ENP shoe cylinders and the crown control cylinder is achieved by two equalizer valves (65, 54). Each valve has a slidable spool with faces of a selected cross-sectional area to respond to hydraulic fluid from the various cylinders to retain the correct proportion between the forces applied by the ENP shoe pistons and the crown control piston.

Abstract: A method and apparatus for bleaching pulp with a gaseous bleaching reagent. The pulp (18) is intensively mixed in the presence of the bleaching reagent within an upstream vessel comprising a fluffer/blower (12). Next, the pulp is agitated in the presence of the bleaching reagent within an intermediate vessel comprising an agitated mixer reactor (14). The pulp is then discharged to a downstream vessel, comprising a porous bed reactor (16), where it is further reacted with the bleaching reagent. The concentration of the gaseous bleaching reagent supplied to each vessel is separately controlled which, in combination with a controlled pulp residence time within at least the agitated mixer reactor and the porous bed reactor, results in an economy of energy utilization, a minimization of pulp particle damage due to mechanical mixing, and uniformity of pulp bleaching.

Abstract: The invention relates to a separating device for winding devices for material webs, particularly of paper or the like, which are longitudinally divided into several partial webs, with at least two rolls (1, 2) being essentially parallel to each other and flexed essentially in the same direction, with a stand (10) for the pivotable arrangement of the rolls about a common swivelling axis, with a support frame (9) for the rotatable arrangement of the rolls about their respective axis of rotation and for the horizontal sweep of the rolls with respect to the stand (10) about the common swivelling axis, whereby at least one transmission pair (3, 5, 8; 8, 6, 4) for the simultaneous, automatic twisting of the deflection line of the flexed rolls during the horizontal sweep of the support frame with respect to the stand is provided in such a way, that the transmissions are necessarily operated by the sweep movement. The basic concept is that through a sweep of the support frame of the two rotary stretchers, the arc alignment of the rotary stretchers is necessarily adjusted with respect to the entering or exiting web. Thereby, any type of subsequent alignment of the arcs of the rotary stretchers in the separating device is completely eliminated.

Abstract: A sheet transfer apparatus (10) is disclosed for transferring a web (W) from a drying section (12) to a calender (14). The apparatus (10) includes a looped felt (16) for supporting the web (W) thereon from the drying section (12). A lead-out roll (18) is disposed upstream relative to the calender (14) for guiding the felt (16) such that the felt (16) is disposed between the lead-out roll (18) and the web (W). A full width web blowing device (20) connected to a source of pressurized air (22) is disposed adjacent to the lead-out roll (18) for selectively blowing the web (W) off of the felt (16). A movable sheet transfer roll (24) is disposed in the vicinity of the lead-out roll (18), the transfer roll (24) being movable from a first position to a second position adjacent to the lead-out roll (18). The arrangement is such that when the transfer roll (24) is disposed in the second position thereof, the blowing device (20) blows the full width web off of the felt (16) and onto the tranfer roll (24) for subsequent guidance thereof to the calender (14).

Abstract: A garbage separation apparatus (20) utilizes a vibrating conveyor (24) to form a thin layer of individual items in a stream of municipal waste (22). The individual items of municipal waste are then transferred to conveyor belts (26) in spaced apart relation. The conveyor belt passes the items of municipal waste under an array of infrared lamps (28). Immediately after being illuminated by the infrared lamps, the items of municipal waste are imaged by an infrared video system (30). The infrared video camera produces a video image wherein specific colors refer to a specific range of temperatures. The output of this video camera is processed to separate mono-temperature images which are processed so as to drive the actuation of individual vacuum grippers out of an array of vacuum grippers (38) placed over the conveyor belt transporting the items of municipal waste. The actuation commands derive from a particular thermal-image depicting a particular range of temperatures and are transmitted to a sequentially arranged adjacent array of vacuum grippers. Thus items of municipal waste may be separated based on their thermal properties.
