Experience

I joined Scott Paper Company in January 1978 as a Research Engineer at the corporate location in Philadelphia.  After working on a number of papermaking projects, I joined the Embossing Development Group in February 1983.  Over the next 13 years, I made valuable contributions in several areas. 
  • Product Development:   I designed and tested hundreds of embossing patterns for markets in Europe, USA, Canada, Mexico, Central America, South America, Asia, and SE Asia.  Many of these patterns were implemented in production with my assistance.  I worked closely with brand leaders and marketing researchers around the world and gained valuable understanding of consumer perception of product attributes.  I designed and led experimental trials on pilot equipment and on full-scale manufacturing lines.  Most of my projects involved embossing of bathroom tissue, paper towels, napkins, and facial tissue.  I also led a project on lotionizing facial tissue. 
  • Rapid Prototyping:   I made many improvements to existing methods of making embossed product prototypes and was instrumental in developing the use of laser engraved rolls and sleeves for pilot embossing.
  • Process Development:   I aggressively pursued the use of laser engraved rollers for applications in manufacturing, and determined the conditions that make this economical.  I also developed the mathematics of positioning the repeating elements of an embossing pattern on an embossing cylinder to minimize certain disadvantages of typical repeating patterns (ridging or corrugation in the rolled product, and grooving in the rubber covered embossing cylinder).
  • Manufacturing Support:   I provided technical support for many startups of new or improved products.  I also helped solve process problems at various manufacturing locations.
  • Seminars and Presentations:   I developed and presented several in-house seminars on how embossing affects product properties, with audiences ranging from very small groups to company-wide conferences. 
  • Understanding Product Attributes and Consumer Perception:   I contributed to the development of a new methodology for measuring handfeel (softness) and other subjective attributes. 

Kimberly Clark acquired (merged with) Scott Paper Company in December 1995.  They offered me a position in their R&D facilities in Roswell GA.  I declined, and started my own consulting company in February 1996.

I am the owner and principal specialist of Embossing Technologies.  I continue to do many of the things I did for Scott Paper Company, and I have since broadened my experience into several new areas.



Publications

My first published article was coauthored with Prof. G. Graham Allan at the University of Washington in Seattle, and appeared in the Romanian journal Cellulose Chemistry and Technology sometime between 1975 and 1977.  The general topic was fiber rheology (deformation of fibers), and more specifically how a helically crimped fiber would bend when subjected to the type of forces applied when testing the "drape" of a nonwoven sheet. 

I wrote a large number of technical memos and reports for Scott Paper Company between 1978 and 1995, all proprietary. 

More recently, I have written or coauthored articles that were published by Paperloop for presentations at trade shows:



Presentations
