Want to know more about web guiding?

Two guiding experts from Fife, Ken Hopcus and John Plumb, have combined to publish a 4-part series in Converting Magazine to answer just about any web guiding question you can think of.
What determines web guide accuracy?
How are actuator sized?
How do you select the right web position sensor?
and the big one...
Which type of guide is right for my application?

Parts 1, 2, and 3 are out already. Part 4 will be out next month.

Full Disclosure: Of course you know that Maxcess Int'l that host this site is the parent company for Fife Corp. Though convertingblog.com isn't intended as an advertising outlet for Maxcess and Fife, I felt this series of articles that emphasize fundamentals and aims a education rather than product promotion.

How hard, that is, resistant to wear, is an anodized alumninum surface?

Quite good, actually.

Here's an interesting link to a Products Finishing magazine article on anodization.

"Anodized Bright; Anodized Tough"

Scroll to the bottom of this page to see an interesting graph of wear testing (using a Taber abraser testor) for anodized aluminum, stainless steel, chrome, regular aluminum and some other surfaces.

Result: Steel is initially more wear resistant, but anodized aluminum wins in the long run (per this test).

More web resources useful to understand roller surfaces:

What surface modification processes produce what range of roughnesses?

One answer, courtesy of Precision Devices, Inc web page (a maker of surface roughness measurement equipment).

1. Surface Profile Parameters
Defines Ra and other roughness parameters and show how they are calculated.
2. Drawing Indication of Surface Texture
A table showing the range of roughnesses typically produced by differ processes and how to indicate surfaced on engineering drawings.

AWEB: The Applied Web Handling Conference
May 6-10, Charlotte, NC

I first gave you the heads up on this new conference last October.

This week, AIMCAL put up the conference program on their website. Look it over. Plan on attending.

Full Disclosure: I'm on the AWEB conference program committee, I'm presenting one or two papers and leading a bonus 1/2 day short course on web wrinkling.

While doing some surfing on roller surfaces this week, I can across a nice roller specifying checklist at the Webex, Inc. website.

Here's their list of the 'ten most critical roller specifications will assist the converter in matching optimum roller performance to system fit and function'

1. Application
2. Quantity
3. Roller material
4. Loading
5. Speed
6. Surface finishing
7. Coatings & coverings
8. Driven or idler roller
9. Elevated temperatures
10. Tolerances

I'm a frequent web surfer. I'll try to keep posting useful sites here at convertingblog.com under the title 'Surf's up!'
