The present teachings relate to an improved deckle board system with a support assembly, actuation assembly, and control assembly to reduce a deckled edge variation.
Typically, fourdrinier paper machines include a wet end with a wire that moves in a machine direction. The wire has a width and stock is applied substantially along the entire width of the wire. A deckle may be used on both edges of the wire to retain substantially all of the stock on the wire. Deckle boards are used to create an edge on a paper machine and to retain stock, water, fines, filler, or a combination thereof on the wire of the paper machine. Some paper machines include a static board that sits on an edge of the wire and prevents stock from exiting the wire from the cross machine direction. Other systems use water to cut the stock and/or slightly dried stock to form an edge on the wire. However, removing stock from the edges decreasing the width of the paper machine resulting in less tons per hour being run. Further, pushing the stock along the cross machine direction may result in an uneven formation along the edges and even towards the center of the sheet so that the sheet includes inconsistencies, which may lead to edges and/or paper being rejected. Pushing stock from the edges of the paper machine may result in waves being sent from one side of the paper machine towards the other side of the paper machine.
Examples of devices for deckling edges of paper are disclosed in U.S. Pat. Nos. 1,712,632; 2,305,300; 3,607,624; 4,738,751 and 4,968,387; U.S. Patent Application Publication No. 2015/0225897 and U.S. Ser. No. 15/155,252 filed on May 16, 2016 all of which are expressly incorporated herein by reference for all purposes. Thus, there is a need for a device that allows users to monitor and control the deckle system from the paper machine or a location remote to the paper machine to ensure proper function of the deckle system. What is needed is a device that removes the deckle system from the wet end so that the wire can be changed without interference or damage to the deckle system. What is needed is a monitoring system that automatically controls the deckle system. What is needed is a monitoring system that allows a user to remotely control the deckle system. What is needed is a shower that creates a boundary layer along both a face and a rear side of a deckle board so that boundary waves are not created at the along the deckle board. What is needed is a deckle board that is flexible and can be moved from a planar shape to a curved shape without damage to the deckle board.

The one or more deckle boards may extend outward as the deckle boards extend in the machine direction such that the cross-machine direction gradually increases in the machine direction. The deckle boards on opposing sides of the paper machine may extend away from each other (i.e., diverge). The deckle boards may be linear, curved, stepped, linear segments with changing slopes, or a combination thereof. For example, the two deckle boards may extend outward so that the two deckle boards form a “V” shape. In another example, the deckle boards may extend outward and form generally two back to back “J” shapes. The deckle boards may be pliable so that the deckle boards generally curve as the deckle boards extend in the machine direction. A slope of the deckle boards may vary from vertical stand to vertical stand (e.g., from segment to segment). A slope of a first segment may be the same as a slope of a second segment. Downstream segments of the deckle board may increase in slope relative to the slope of the first segment, the second segment, or both. The first segment, the second segment, or both may have a slope that is substantially undefined (i.e., rise=a value and run=0) (e.g., a slope that is generally parallel to the machine direction (e.g., slope within about 0.5 or less, about 0.3 or less, or about 0.1 or less from an undefined slope).

The slope from segment to segment may vary buy about 100 or less, about 50 or less, about 25 or less, or even about 10 or less. A change in slope may increase as the deckle board extends in the machine direction. For example, the amount the deckle board curves outwards may increase as the deckle board extends in the machine direction, thus increasing the rate of change of the slope. For example, a change in slope between the second segment and the third segment may be about 3 and the change in slope between the third segment and the fourth segment may be about 15. The slope may vary within a segment. The slope at a beginning of a segment to an end of a segment may vary by about 100 or less, about 50 or less, about 25 or less, or about 10 or less. The slope may vary within a segment. The slope at a beginning of a segment to an end of a segment may vary by about 0.1 or more, about 0.5 or more, about 1 or more, or about 5 or more. Preferably, the deckle board curves in the machine direction as the deckle board extends away from the head box so that the deckle board has an exponential curve (i.e., the curve of the deckle board increases at a greater rate as the deckle board extends away from the head box). The slopes of the segments may become larger as the segments extend away from the headbox, thus, the first segment may be less than all subsequent segments, the second segment may be the same as or greater than the first segment, the third segment may be the same as or greater than the first segment and the second segment, and so on.

The seal strip may be compliant so that the seal strip moves with angle adjustable foil blades, height adjustable foil blades, or both and prevents stock from passing under the seal strip. The seal strip may move with the foils as the foils are adjusted so that stock is retained on the wire. The seal strip may be a low friction material. The seal strip may be made of polytetrafluoroethylene, coated with polytetrafluoroethylene, include polytetrafluoroethylene, or a combination thereof. The seal strip may include a plurality of slots. The plurality of slots may function to connect the seal strip within the deckle board. The plurality of slots may function to allow for expansion, contraction, or both of the seal strip. The plurality of slots may include one or more connection slots and one or more expansion slots.
The connection slots function to prevent the seal strip from being removed from the deckle board, entirely moved in the machine direction, or both. The connection slot may allow for a fastener to extend through the seal strip. Preferably, the seal strip includes at least one connection slot for preventing movement of the seal strip in the machine direction; preventing the seal strip from being pulled by the wire, stock, or both. However, the seal strip may include a plurality of connection slots. More preferably, the single connection slot is the slot located closest to the head box. The connection slots may be round, oval, a slit, a through hole, or a combination thereof. The seal strip may include a plurality of expansion slots that are located adjacent to the connection slots and in a successive row.
The plurality of expansion slots may allow the seal strip, the deckle board, or both to thermally expand and contract relative to each other so that the seal strip retains its planar shape, is free of waves, is free of wrinkles, or a combination thereof. The plurality of expansion slots may allow for thermal expansion and contraction of the deckle board and seal strip at different rates so that the seal strip is free of contact with the fasteners and is not warped. The plurality of expansion slots may allow for the seal strip to move in the machine direction and be free of contact with a fastener, be free of resistance from a fastener, or both. The one or more expansion slots may be an absence of material on the upstream side, the downstream side, or both of each fastener so that the seal strip is free to move in the machine direction. The expansion slots may be sufficiently large so that upon maximum thermal expansion and/or thermal contraction of the deckle board and seal strip relative to each other the walls of the expansion slots do not contact the fasteners. The expansion slots may be open. The expansion slots may have one or more walls that extend to a terminal edge so that a gap is created between an adjacent wall. The expansion slots may be generally “U” shaped. The expansion slots may allow for removal and/or replacement of the seal strip without removal of all of the fasteners. For example, only the connection fastener may need to be completely removed to remove the seal strip and add a new seal strip installed in the deckle board and the pressure fasteners may only need to be loosened. Thus, in another example, upon removal of the connection fastener and loosening of the pressure fasteners the seal strip may be pulled out from between the deckle board clamp and the seal strip clamp and a new seal strip installed. The seal strip may be a plurality of individual pieces that may be connected together to form one continuous piece. The seal strip may extend the entire length of the forming section (i.e., from the breast roll and/or head box to the couch roll). The seal strip may be retained within the deckle board by one or more fasteners.
The fasteners may function to connect the one or more seal strips within the deckle board, to the deckle board, or both. The one or more fasteners may extend through the seal strip, create pressure on the seal strip, or both. Preferably, only one fastener extends through the seal strip (i.e., a connection fastener). The connection fastener preferably is the first fastener, is located proximate to the head box, or both although the connection fastener may be located downstream of the head box (e.g., in a second or third slot). The one or more and preferably a plurality of fasteners (i.e., pressure fasteners) may create pressure on the seal strip. The plurality of fasteners may be a plurality of pressure fasteners that create a clamping force on the seal strip to retain the seal strip proximate to the deckle board. The plurality of fasteners may connect the deckle board clamp and the seal strip clamp together. The plurality of fasteners may connect the deckle board to the head box.
The deckle board system may include a head box attachment that attaches the deckle board system to a location proximate to the head box, to the head box, the breast roll arm, or a combination thereof. The head box attachment may be a single point of fixed attachment (i.e., is not movable). The head box attachment may create an anchor that prevents the deckle board system from moving in the machine direction, although the deckle board system may be extendable and/or expandable in the machine direction. The head box attachment may attach to one or more shower systems or may connect the deckle board and the one or more shower systems to the paper machine.
The one or more shower systems may function to clean the deckle board system. The one or more shower systems may function to prevent a buildup of stock on any deckle board components. The shower system may function to create a boundary layer. The shower system may function to prevent stock build-up on any parts of the deckle board system. The shower system may create a continuous waterfall of water on the stock side, non-stock side, or both of the deckle board. The shower system may cascade water over the top of the deckle board to clean the deckle board, create the boundary layer, or both. The shower system may provide water equally to the stock side and non-stock side of the deckle board. The shower system may provide water along the deckle board in the machine direction. For example, the shower system may spray water in the machine direction so that the water forms a fluid barrier between the stock and the deckle board. The shower system may spray water in the machine direction so that a velocity difference between the stock and the fluid boundary layer is minimized so that the fluid boundary layer prevents waves, disruptions, or both on the edges of the stock. The shower system may include one or more shower bars, one or more shower nozzles, or both that apply a spray to the deckle board. The one or more shower systems may be two or more, three or more, or even four or more sets of shower systems.

The upper shower system may function to create a constant waterfall of water across the deckle board, a curtain of water, or both on the one or both sides of the deckle board. The upper shower curtain may provide water on the top of the deckle board so that water flows on both sides. The upper shower curtain may gravity feed water to the top of the deckle board. The upper shower may spray water on the top of the deckle board with a pressure of about 35 kPa or more, about 70 kPa or more, about 105 kPa or more, or even about 140 kPa or more. The upper shower may spray water on the top of the deckle board with a pressure of about 500 kPa or less, about 400 kPa or less, about 300 kPa or less, or even about 200 kPa or less. The upper shower may provide a sufficient amount of water so that a boundary layer is provided between the deckle board and the moving stock. The amount of water may vary based upon the speed of the wire. For example, if the wire is moving 100 m/min each nozzle may apply 2 L/min and if the wire is moving 200 m/min each nozzle may apply 4 L/min. The amount of water applied to the deckle board may be any amount of water discussed herein. The upper shower may provide spray, water, or both behind a boundary layer system. The water may be applied in such a manner that surface tension of the water applied may maintain the water proximate to the deckle board, the seal strip, or both. The upper shower system may be used alone or in conjunction with a lower shower system.
The lower shower system may be located entirely on the non-stock side of the deckle board. The lower shower system may function to direct fluid at the seal strip, under the seal strip, or both. The lower shower system may create turbulence at the seal strip, on the seal strip, or both. The lower shower system may provide a boundary layer of water at the seal strip, under the seal strip, in front of the seal strip, or a combination thereof. The lower shower system may prevent a seal from being formed between the seal strip and the wire, forming table, foils, or a combination thereof. The lower shower system may have a low angle trajectory. The lower shower system may be angled so that any waves on the wire, forming table, or both are negated by the spray of the lower shower system. The lower shower system may dampen any waves on the wire, forming table, or both. The lower shower system may direct water at an angle of about 2 degrees or more, about 5 degrees or more, about 7 degrees or more, about 10 degrees or more or even about 15 degrees or more from horizontal to a location proximate to the seal strip. The lower shower system may direct water at an angle of about 45 degrees or less, about 30 degrees or less, or about 20 degrees or less from horizontal (e.g., a plane of the wire surface) to a location proximate to the seal strip. The lower shower may spray water at the non-stock side of the deckle board, at the seal strip, or both with a pressure of about 35 kPa or more, about 70 kPa or more, about 105 kPa or more, or even about 140 kPa or more. The lower shower may spray water at the non-stock side of the deckle board, the seal strip, or both with a pressure of about 500 kPa or less, about 400 kPa or less, about 300 kPa or less, or even about 200 kPa or less. The upper shower system and the lower shower system may span all or a portion of the length of the wet end, the forming table, the wire, or a combination thereof. The upper shower system and the lower shower system may mirror each other. For example, the nozzles of the upper shower system may be longitudinally located at a same distance as the nozzles of the lower shower system. The nozzles of the upper shower system and the nozzles of the lower shower system may be staggered, aligned, or both. The upper shower system, lower shower system, or both may be used in conjunction with and/or replaced by one or more end showers.

The one or more end showers may function to provide additional water to the ends of the deckle board. The one or more end showers may provide additional cleaning to the ends of the deckle boards. The one or more end showers may only be located at the head box end and may create turbulence at the beginning of the deckle board. The one or more end showers may spray directly on the face of the deckle board. The one or more end showers may double the amount of water added to the deckle board at discrete locations. The end shower may deliver a similar amount of fluid at a similar pressure to what is described herein for the upper shower system and lower shower system, the teachings of which are incorporated herein. The one or more end showers may include a shower bar that extends outward away from the deckle board and then curves back towards the deckle board. The end shower may be located above and/or adjacent to a boundary layer shower.
The boundary layer shower may function to form a boundary layer of fluid (herein after water, but the water may include paper machine chemicals, fines, be recycled paper machine water, or a combination thereof) between the stock and the face of the deckle board. The boundary layer shower may function to hydraulically form a deckled edge. The boundary layer shower may form current, eddies, turbulence, or a combination thereof along an edge of the deckle board so that a deckled edge is formed. The boundary layer shower may provide water at a sufficient velocity so that shear between the boundary layer water and the stock is minimized, reduced, and/or eliminated. For example, the boundary layer water may be sprayed in the machine direction so that the boundary layer water does not create a high amount of drag on the stock so that build up is formed. The boundary layer shower may function to provide water that forms a boundary layer at substantially the same speed as the stock is moving. The boundary layer fluid may be sprayed at a speed within about 200 m/s or less, about 150 m/s or less, or even about 100 m/s or less of the machine speed. Thus, for example, if the machine speed is about 1000 m/s the speed of the fluid directed from the boundary layer shower may be about 900 m/s or less. The boundary layer water may lubricate the face of the deckle board so that stock is prevented from collecting and so that thickness, caliper, density, basis weight, or a combination thereof are not affected at the dry end. The boundary layer shower may function to keep stock moving in the machine direction, prevent laminar flow from forming proximate to the seal strip, the deckle board, or both. The boundary layer shower may eliminate waves in the stock, on the forming section, on the wire, at the edges, or a combination thereof. The water from the boundary layer showers may run down the face of the deckle board and in the machine direction so that upon contact with stock waves are dampened, dissipated, eliminated, reduced, or a combination thereof. The boundary layer water may prevent waves from extending from the edge back towards the center. For example, any waves that are generated may be eliminated upon contact with the boundary layer water from the boundary layer shower. The boundary layer shower may provide water that clears the face of the deckle board, the seal strip, or both so that stock is exposed to a uniform surface along the machine direction. The boundary layer shower may provide spray against the machine direction (i.e., in an opposite direction as the stock is moving). The boundary layer shower may provide spray in the machine direction so that the stock and the deckle board are free of contact, do not contact each other, or both. The boundary layer shower may provide water at an angle of about 5 degrees or more, about 10 degrees or more, about 15 degrees or more, about 25 degrees or more, or even about 40 degrees or more from vertical. The boundary layer shower may provide water at an angle of about 90 degrees or less, 75 degrees or less, about 60 degrees or less, or even about 45 degrees or less from vertical. The boundary layer shower may have a fan configuration so that a portion of the spray extends vertically and a portion of the spray extends at an angle of about 90 degrees from vertical. The spray may extend out of the shower nozzles at an angle. The angle of the spray extending out of the shower nozzles may be about 5 degrees or more, about 10 degrees or more, about 15 degrees or more, about 25 degrees or more, or even about 30 degrees or more.
