摘要:
A monitoring system comprising: (a) one or more sensors that monitor activity, amplitude, size, scale, duration of activity or a combination thereof of stock on a paper machine and (b) a control system in communication with the one or more sensors and one or more foil sections within the paper machine; wherein the control system measures the activity, amplitude, size, scale, duration of activity or a combination thereof of the stock and correlates the activity, amplitude, size, scale, duration of activity or a combination thereof to formation of fibers within the stock so that an angle, height, or both of the one or more foil sections are adjusted to change the activity, amplitude, size, scale, duration of activity or a combination thereof in the stock.

An improved method for producing paper from pulp includes a plurality of subassemblies arranged in the forming or wet section of a Fourdrinier. The Fourdrinier includes a dewatering table having a plurality of blades that are static and on-the run adjustable in height and/or angle to control orientation of paper fibers in the stock to create a superior quality of paper and improved paper strength characteristics. Gravity and vacuum assisted drainage elements are equipped with on-the-run adjustable angle and height dewatering foil blades starting from a paper dryness of 0.1% and extending all the way to 5% dryness. The result of this process and machine is to improve the paper quality, save fibers and chemicals and fulfill the required paper properties.
摘要:
An apparatus for introducing an endless fabric loop over rolls in a paper making machine in connection with changing the fabric therein comprising an inflatable changing bag which, upon being inflated, has a vertical cross-sectional configuration in the machine direction which is substantially the same as the configuration of the intended run of the fabric loop over the rolls. The changing bag is located in its deflated condition within the fabric loop which is to be introduced over the rolls whereupon the bag is inflated with the fabric loop encircling the same. The assembly of the inflated changing bag and the encircling fabric loop is located on one side of the paper machine in the region adjacent to the rolls onto which the fabric loop is to be introduced whereupon the fabric loop is moved from over the inflated changing bag onto the paper machine so that it encircles the rolls. The changing bag is preferably provided with a plurality of interior partitions which divide the bag interior into a plurality of independent airtight compartments, each of which extends in the machine direction. As the fabric loop is pulled from the changing bag onto the rolls, the compartments are successively deflated to facilitate the introduction of the fabric loop over the rolls.

A draping system, for use in clothing a pulp forming section with an endless belt, has a rigid top frame to receive a plurality of substantially rigid poles in mutually parallel, loop supporting relation thereon, and a lightweight lower frame having semi-rigid poles for insertion within the loop of the belt and detachable spacers for holding the semi-rigid poles in spaced apart relation, the lower frame being sufficiently light to be readily supported within the belt in loop extending relation by the belt, for transverse insertion into a forming section.

A PORTION OF A PAPERMAKING MACHINE IS DISCLOSED WHERE PAPER STOCK DISCHARGE FROM A HEADBOX IS DEPOSITED UPON A FOURDRINIER TYPE WEB FORMING WIRE PROVIDED WITH DRAINAGE FOIL ASSEMBLIES BENEATH THE WIRE (SUBSTITUTED FOR TABLE ROLLS), AND A FOIL ASSEMBLY IS SUPPORTED BENEATH THE WIRE BY A SUPPORT MECHANISM CARRIED ON RAILS BENEATH AND PARALLEL TO THE EDGES OF THE WIRE. THE ASSEMBLY INCLUDES A BODY WHICH IS CONNECTED TO THE SUPPORT MECHANISM AND A FOIL CAP MOUNTED ON TOP OF THE FOIL BODY. THE FOIL BODY AND FOIL CAP ARE PROVIDED WITH A DOVETAIL CONNECTION THEREBETWEEN, A CLAMP BAR OVERLAPPING BOTH THE BODY AND CAP AND PIVOTALLY CONNECTED TO THE BODY, AND A FLUID PRESSURE INFLATABLE TUBE BETWEEN THE BAR AND BODY ON A SIDE OF THE PIVOTAL CONNECTION OPPOSITE THE CAP, THE SECURELY CLAMPING THE CAP TO THE BODY UPON INFLATING THE TUBE.
