Future Blogs

I plan on doing some posts on the following topics (to name a few):
  • Tapio RQP (roll hardness) applications
  • Gauge R & R
  • FPMonitAir (entrained air) applications
  • Zeta potential applications
  • Tissue softness applications
  • Standards committees
  • PaperCon '13, Atlanta, GA 
What are some other topics you would like to see covered?  Email me at

Building an Automated Test System Makes Sense

Technidyne's PROFILE/Plus automated test system has existed for over 12 years.  It was the first modular approach to automated testing in the Paper Industry.  Approximately 700 modules have been sold over the years.  These PROFILE/Plus modules reside in about 250 different locations in 21 countries around the world.  Currently, there are 43 systems with an average of 5 modules/system.  Before the PROFILE/Plus modular concept customers had to purchase an entire 'big-box' system all at once. To justify the US$1 Million price tag, people were eliminated.  By contrast most PROFILE/Plus systems were built over time. Many PROFILE/Plus systems were started with an initial investment of US$15,000.  Manpower is usually reallocated to more important, analytical tasks after PROFILE/Plus implementation since the automated system provides efficient, frequent, quality data on each roll of paper. 

The US$1 Million price tag for a 'big-box' system doesn't even include the cost to install the 10 ft X 5 ft structure into the lab.  PROFILE/Plus modules sit on the existing counter top.

Over time, as testing needs and strategic objectives change PROFILE/Plus systems can be reconfigured to accommodate this.  In some cases a single system is split into two systems. This is simply not possible with traditional, 'big-box' systems, and the investment is thousands of dollars instead US$500,000 or more.

Since the inception of the PROFILE/Plus product line, compatibility has been a core feature.  As an example, Technidyne still maintains Hagerty Technologies smoothness, porosity and opacity modules which are over 20 years old.  Therefore, if you are building a system over time, you can feel confident that you won't have to be concerned about compatibility.

Recent Standards Committee Activities (Feb. 2013)

TAPPI issues a Standards & TIPS Action Report (STAR) on a regular basis to keep industry personnel up to speed with activities in various committees and organizations.
TAPPI STAR - February 2013


Some highlights include:
  • New or revised TAPPI Standards
  • Announcement of TAPPI Standards in Ballot
  • Proposed new Standards
  • 26 TAPPI Standards coming up for review
  • Announcements - How to propose a new Standard or Technical Information Paper (TIP)
  • Where to access the list of suppliers providing equipment and supplies for TAPPI Standards
  • A list of common acronyms:
    • TIP = Technical Information Paper
    • SSIG = Standard-Specific Interest Group
    • om = Official Method
    • pm = Provisional Method
    • cm = Standard Practice
    • UM = Useful Method
  •  How to search and order TAPPI Standards
Technidyne is actively involved in organizations such as TAPPI, ISO and PAPTAC to ensure there are meaningful and usable standards for us in the Paper Industry.

Predicting Roll Runnability

The Tapio RQP can be used quite effectively to rank rolls and predict their runnability.

Statistical ranking of the rolls

This statistical ranking of the rolls is accomplished by using the COV% roll hardness and mean hardness (D. Wanigaratne, Appita 2010).  This can be seen in the graph above.  Groupings can be developed

Rule of thumb in determining poor roll structure (D. Wanigaratne, Appita 2010)
