Filed:

Apr 21, 2012

Appl. No.:

13/506470

Inventors:

James Faufau - Alpharetta GA, US
Andrew Forester - Schoolcraft MI, US

Assignee:

IBS Corp. - Chesapeake VA

International Classification:

D21F 11/00

US Classification:

162208, 162209, 162348

Abstract:

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.

Appl. No.:

10/036263

Inventors:

Andrew Forester - Wrightstown WI, US

International Classification:

D21F001/54
D21G003/00

US Classification:

162/352000, 162/281000

Abstract:

A hydrofoil blade having a top surface with a leading edge in contact with a forming fabric and a trailing edge, and a leading side surface disposed transversely to the direction of movement of said fabric upstream of and generally at an acute angle to the top surface thereby draining water from the stock. A plurality of slots extend at an acute angle from the leading side surface to a point between the leading and trailing edges on the top surface to force a portion of the drained water back into the stock, whereby any flocs formed in the stock are dispersed in the transversal shear generated by the drained water.

International Classification:

D21F 1/26
D21F 1/56
D21F 1/48
D21F 1/80

Abstract:

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.

Abstract:

Improved height and angle adjustment mechanisms and methods for producing paper includes a plurality of height and angle adjustment mechanisms arranged in the forming or wet section of a Fourdrinier. Glide shoes and cam-blocks having sloped grooves are arranged to be driven within a recess of an upper pultrusion assembly to change the angle or height of a particular foil blade. Actuators extend or withdraw a connecting rod, coupled to the cam-blocks, to influence heights and angles of various foils blades.
