Why WrinkleSTOP®?
  • Linear face = zero web destortion
  • Smooth surface = zero web marking or scratching
  • Adjustablity = web spreading where wrinkles are the worst
  • Aggressive wrinkle removal = less waste for fast return on investment

Why use any other type of anti-wrinkle roll?

Technical Report:
Webs without wrinkles

"Only a few degrees short of perfection, expanding surface spreader rolls shine with thin gauge webs."

An impartial examination and evaluation of the performance of all wrinkle-removing systems came in a definite study published in a bound edition, edited by J. K. Good, of the Fourth International Conference on Web Handling, held June 1-4, 1997, at the Web Handling Research Center, Oklahoma State University, Stillwater, OK. The specific study, "Testing and Analysis of Web Spreading and Anti-Wrinkle Devices" by R. P. Swanson, 3M Company, (pp414-428), found "the expanding surface rollers did not wrinkle under any test conditions. The regime 1 (one) performance was excellent. This roller is an aggressive web-spreading device. An expanding surface roller would be insensitive to wrinkles at low, medium, and high tension. This roller is an excellent, high drag, web spreading and anti wrinkle device."(p421). Of the ten types of systems tested, only the expanding surface spreader rolls and the "curved axis" or bowed roll systems were described as "excellent" systems according to the study.

Features:

  • Aggressive wrinkle removal with zero-web distortion.
  • Bowless, smooth roll does not mark or distort the web.
  • Independent edge-to-edge adjustability while the web is in motion.
  • No special tools needed to adjust degree of spreading action.
  • Works well in vacuum chambers and can be used to run in high-heat applications.
  • Easy installation.
  • Accepts and delivers web at any angle.
  • Surface designed for high traction.
  • Works well with extremely short lead-in and lead-out web distances.
  • Drive sheave available: perfect for light webs.
