Narrow (or is it) Web Handling

Posted by David Roisum on January 12, 2012

I am thinking of signing up for your course.  Does web handling apply to narrow webs?

Narrow webs are sometimes defined as less than 1 meter wide.  Most web-handling directly applies to narrow webs.  A few exceptions occur on the narrowest of the narrow, i.e., ribbon-like materials.  For example, spreading and wrinkling are both neither so helpful nor troubling, respectively and relatively.  Also, air entrainment does not exist because of edge effects and very narrow webs are nothing but edges.  Finally, certain wound roll defects, such as corrugations, can not exist on very narrow webs.  However, these differences involving only a fraction of the area are a matter of degree rather than principle so you should probably think seriously about taking The Course.

Tim Walker, Dilwyn Jones and myself will be teaching half-day winding and wrinkling shortcourses at the Web Handling conference June 13-15 in Prague. This is in addition to two days of papers given by ourselves and other luminaries of web handling and in addition to similar fare in coating earlier in the week.

Also, you and your coworkers can, at your leisure, attend a virtual audio/slide version of any or all of my schools. This include some 60 modules on a variety of web-handling, winding, troubleshooting and related topics. All told, there are about 10 days or 1,000 slides worth of training. You can get this with an annual subscription https://www.aimcal.org/technical-resources/bookstore/item/productid/66.aspx. Finally, I am working on converting some of the more popular of the 60 modules to video-on-demand as we speak.

No more excuses not to go to school :\
