Title: Thomas N. Kershaw: Innovator in Absorbent Paper Products

Introduction

Thomas N. Kershaw is a prolific inventor based in Neenah, Wisconsin, known for his extensive contributions to the field of absorbent paper products. With an impressive portfolio of 44 patents, Kershaw has made significant advancements in tissue design and production methods, enhancing both functionality and user experience.

Latest Patents

One of Kershaw's latest innovations is the multi-ply absorbent paper product featuring an impressed pattern. This multi-ply tissue incorporates a first cellulosic embossed ply with an emboss pattern on part of its surface, coupled with a second cellulosic embossed ply. The first ply is contact laminated to the second ply, creating primary adhesion through the contact of cellulosic fibers. The configured contact areas between the plies not only define compliant voids but also employ elongated and/or rounded contact areas, optimizing absorbency and softness. Moreover, Kershaw has developed a method for forming a multi-ply tissue that involves feeding a base sheet through a nip between an impression roll and a pattern roll, followed by applying adhesive and a flat backing sheet in a manner that improves the overall structural integrity of the product. He has also created a method for producing an embossed tissue that utilizes a rubber second impression roll with lower hardness than the first, ensuring improved texture and performance.

Career Highlights

Throughout his career, Thomas N. Kershaw has been associated with notable companies such as Fort James Corporation and James River Corporation of Virginia. His work has had a lasting impact in the paper manufacturing industry, especially in the development of high-quality tissue products.
