Provisional Patent Application No. This disclosure relates to edge trimming equipment and methods for trimming unwanted edges from a moving paper web or board. This disclosure further relates to edge trimming that is carried out on a structured papermaking fabric, for example, a transfer fabric, a dryer fabric, or a roll.
Still further, this disclosure relates to edge trimming equipment and a method for continuous trimming of a moving web in a paper machine using a water jet which minimizes rewet. This disclosure also relates to an edge trimming system that includes air separation of the unwanted trim from the remainder of the web, allowing the trim to be captured and reused in the process.
In one embodiment, the disclosure relates to a method for trimming an unwanted edge from a moving paper web by 1 making a trim cut in the paper web when it is on a structured papermaking fabric in the drying section of the paper machine; 2 removing the unwanted section of edge trim from the fabric before the pressure roll; and 3 guiding the excess trim to the Yankee pulper for reprocessing.
In another embodiment, this disclosure relates to an apparatus for trimming an unwanted edge from a moving paper web including a water nozzle for cutting the web; an air ejection system for removing the unwanted trim from the remainder of the web; and, a trim conveyor for guiding the unwanted trim away from the papermaking machine.
In papermaking processes, water jets are commonly used to cut through the traveling web. Water jets have been used in leader-cutting, edge trimming, slicing, cross-cutting and tail-cutting operations during the papermaking process. Low pressure water jets have been used in the wet-end of the process allowing the cutting of the web against the forming wire. Low pressure cutting works in the wet-end of the papermaking process because the consistency of the web is low in the wet-end making it easier to cut.
As the solids content, i. If the pressure is too low, the cut will end up ragged and irregular. Processes for cutting the web in the dryer section, where the solids content is necessarily higher, have been contemplated. However, the nozzle size has traditionally been large to assure an adequately sized cut in the web.
One method of Marge simpson playboy prior art has considered using high pressure water jets for leader or tail cutting against parts of the papermaking machine.
This method was used only against a cylinder, Vac-roll, paper guide roll or in free draw, not against a structured fabric. Finally, water jets have heretofore been paired with collection chutes in edge trimming operations to remove the unwanted trim. The process as disclosed herein uses a nozzle having a diameter of less than about 0.
Still further, this small nozzle allows the edge to be trimmed away against the structured papermaking fabric without damaging the fabric. The process includes the removal of the unwanted trim by an air ejector proximate the cutting nozzle. Since the cut made by this small nozzle is itself small, the cut can re-fuse, making the Twin fourms edge impossible to remove, unless it is removed by an air ejection system.
Finally, the process of the invention uses the air ejection system to move the trim to a trim conveyor for movement away from the papermaking machine.
The present disclosure describes a method and apparatus for trimming the unwanted edge from a moving paper web while that web is being carried through the drying section of a paper machine on a structured drying fabric, e.
This unwanted material is generally returned to the process for repulping and reuse. The moving paper web may be produced by any art recognized method, that uses a structured papermaking fabric in its drying section.
The method for making the paper web may include a Yankee dryer or it may not, for example, TAD. In process Pick on full slip cantaloupe a Yankee dryer, the edge trim will generally occur on the transfer fabric to the Yankee, before the pressure roll. In a TAD process, the edge will likely be trimmed on the wire or on the dry-end of the paper machine.
The water nozzles used to produce the cuts in the paper web are very small. Each water nozzle is typically less than about 0. The water supplied by the nozzles may be at ambient temperature, may be heated, or may be superheated. In one embodiment, the water used with such small nozzles may be subject to strict filtration requirements.
In another embodiment, the water used with such small nozzles may need to be softened. In yet another embodiment, the water may be both softened and filtered. The water is applied at a pressure of form about 0 psig to about psig, such as from about psig to about psig.
In one embodiment, the nozzle assembly includes 4 shower assemblies. In another embodiment the nozzle assembly includes 3 shower assemblies, In still another embodiment, the nozzle assembly includes 2 shower assemblies According to one embodiment, the shower assemblies include an inline pressure gauge positioned before the nozzle.

In another embodiment, the shower assembly includes an adjustment and lockdown mechanism allowing for quick adjustment for cross-machine direction positioning and alteration of the nozzle angle.
According to another embodiment, the shower assemblies may include a quick disconnect allowing for rapid changing of nozzles. According to another embodiment each nozzle may be adjusted independently.
According to one embodiment, the nozzles are oriented toward the outside of the web in the cross direction. In another embodiment the entire nozzle block may be moved together. The upper limit for moving the nozzle away from the paper web is when the water jet breaks up and is no longer effective. In one embodiment, the nozzle assembly includes at least two shower assemblies that are offset from one another in the machine direction. The arrangement allows the nozzles to make two cuts which can define a smaller unwanted trim portion.
This smaller unwanted trim is generally located between the moving web and the remaining unwanted trim. In this embodiment, the smaller unwanted trim portion can be removed proximate the web cutting while the remaining unwanted trim can continue in the process to be removed later, for example from the Yankee dryer.
This embodiment will be discussed below in reference to FIG. Following the cutting Trim squirt positioning the web the unwanted trim is removed from the structured papermaking fabric.
Any art recognized method for removal can be used. In one embodiment, the air ejection system and the cutting nozzle are carried on a master assembly to maintain their relative position despite repositioning the cutting nozzles.
Air ejection systems that can be used in the present disclosure include air knives and blow-off pipes. In one embodiment, the air ejection system is on the opposite side of the structured paper fabric from the cutting nozzle. The rate of re-fusion of the cut web will depend to some extent upon the weight of the paper web, and the amount of residual water in the paper web at the time of cutting.
The skilled artisan, based upon the paper to be cut, can determine an appropriate proximity for the air ejection system. The pressure of the air is between about 0 psig and about 80 psig, such as between about 20 psig and about 70 psig. The air pressure is adjusted in response to the behavior and direction of the unwanted piece of trim.
The unwanted trim is blown by the air ejection system into a collection apparatus. In one embodiment, the air ejection system is positioned even with the start of the collection apparatus.
