Web Handling And Converting
AIMCAL will again be holding its annual US web technical conference in partnership with the Society of Plastics Engineers. Sought are papers in the areas of adhesion, coating, vacuum coating, drying and web handling. Deadline for the paper submission for the October 15-18, Naples Florida conference is soon. Speak, attend, learn. I will be there doing all three and then some. http://www.aimcal.org/call-for-papers2.html.
There are a couple of features that are unusual and unique to textiles that affect baggy web troubleshooting. The unusual part is their edges are proportionally thicker than almost any other web material. The unique part is their forming process can make severe bagginess. This is called ‘tight ends’ in textile parlance. In contrast, most other materials are formed flat but are simply uneven in thickness.

Foil must be much more level than the more typical 1-10% that other materials have as their ‘threshold of customer pain.’ Part of the reason is ‘merely’ cosmetic. You can see bent foil from across the room thus a comparison between you and your competitor will be instant and vivid. Part of the reason is quite practical. Foil is ready to wrinkle if you merely look at it crosswise. Adding bagginess means you don’t even need to look, it is wrinkled already.

Mark your calendars for the best web-handling training (May 16-17) and only two day training in winding (May 18-19). This award winning and trademarked class has been taken by about 5,000 students and is considered essential for anyone working with webs. The instructor is Dr David Roisum who has written uncountable articles, books, blog posts, columns, papers and the like. He also has much experience having been into around 1,000 plants so that the class material is field tested, so to speak.

While we have said much about film in this troubleshooting series, I would like to highlight a few engineering best practices. This modeling/measurement approach is proactive instead of reactive.
