High Traction Idler Rolls

High traction idler rolls - for the coating, laminating, printing and converting industries.

 

Two Problems: Slippage and Creasing

Proper idler performance is a critical parameter in your high speed conveyance process. If the idler rolls slip, scratches and resultant particle contamination dramatically increase product defects.

Misaligned idlers and/or excessive web tension cause web creasing and foldover leading to waste.

 

One Solution:

Our precision-made High Traction Idler Rolls solve both of these problems and have demonstrated their superiority in the extremely demanding manufacture of magnetic tape.

Slippage
Idler slippage caused by the boundary layer effect can occur at web speeds as low as 200 fpm, well below typical process speeds.

Just 1/3 the weight of conventional rolls to minimize inertia, our High Traction Idler Rolls have a special hardened surface finish which resists abrasion.

The special surface finish breaks the boundary layer and maintains equal web-idler speed in high speed, thin film, low tension web-conveyance operations.

Creasing
The High Traction Idler Roll design also eliminates web creasing and foldovers caused by tension lines.

The High Traction Idler Roll acts as a spreading device on thin webs, imparting lateral forces on the film, maintaining flatness and stability across the entire width.

 

Many Applications:

System Retrofits
The High Traction Idler Roll is a cost effective way to upgrade an existing system. Make the conversion to thin web or higher speed conveyance without the installation of expensive helper devices or web spreaders.

The High Traction roll easily replaces conventional idlers. Available in standard support as well as cantilevered design.

Lower Tension Conveyance
The high traction characteristics of our Idler Roll make it ideal for low tension applications.

Example: lower tensions are required in magnetic tape solvent dryers. Dryer temperatures can significantly deduce the yield strength of base film.

Permanent dryer temperatures exceed 90C. High Traction Idler Rolls run successfully at tension as low as 1/4 pli to eliminate base film deformation!

Incorporate our High Traction Idler Rolls into your low tension line for the same success.

Quality Upgrade
Immediate product quality improvements are achieved by integrating our High Traction Idler Rolls into your process. Eliminate scratching and creasing, and gain the benefits of lower yields losses and immediate investment payback!
