US Patent:

6375801, Apr 23, 2002

Filed:

Sep 5, 2001

Appl. No.:

09/948032

Inventors:

Stephen Percival John McGary - Huntsville, CA
Scott A. Baum - Madison WI
Paul Douglas Beuther - Neenah WI
Robert Paul Guarnotta - Evans GA
Richard Martin Urquhart - Broken Arrow OK

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

B65H 2324

US Classification:

162199, 162198, 162202, 162111, 226 7, 226 973, 34444

Abstract:

In manufacturing a moving web, such as a tissue sheet, the web is transported at very high speeds, often in an unsupported manner, which can result in unstable operations regarding handling and winding of the web. This is particularly true in the region between the creping blade and the reel for a lightweight, low modulus tissue sheet that is characteristic of a high-quality, soft tissue basesheet. To provide an improved means of controlling the tissue web during manufacture and to improve the manufacturing rate, an apparatus and method of stabilizing the moving web that incorporates a creping blade foil, one or more aerodynamic sheet stabilizing foils, and a roll foil in a specific relationship to each other is disclosed. This method has been shown to improve the stability of a moving tissue web, allow for a higher rate of operation, and enable the production of softer tissue basesheets.

International Classification:

G01G 11/02

US Classification:

356635, 356431

Abstract:

A measurement system for measuring a parameter of a log is provided. A measuring device produces an emission in a direction of the log. A portion of the emission measures the parameter, such as log diameter, and communicates the diameter to the measuring device, which in turn communicates the diameter to a controller to selectively adjust converting equipment to vary the diameter.

Appl. No.:

9/290746

Inventors:

Richard Martin Urquhart - New Milford CT
Paul Douglas Beuther - Neenah WI

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

D21F 106

US Classification:

162212

Abstract:

An apparatus and method for forming a thin fibrous mat, such as a tissue sheet, with improved edge strength is disclosed. The apparatus includes a headbox having a top, a bottom, a pair of lateral sides, a back with an inlet formed therein and a front with an outlet formed therein. A first conduit is connected to the inlet of the headbox and flow therethrough is regulated to convey a first aqueous slurry at a desired flow rate into the headbox. The first aqueous slurry has a predetermined fiber consistency. A second conduit is connected to one of the lateral sides of the headbox and a second aqueous slurry is directed therethrough into the headbox at a different flow rate than through the first conduit. The apparatus also includes a mechanism for drying or draining water from the aqueous slurry exiting the outlet to form a thin fibrous mat. The thin fibrous mat has increased strength adjacent to an edge located downstream from the second conduit.
