The proper application, through Engineering surveys, will allow users of Applied Roller Technology, Inc. Spreader Rollers to achieve an efficient, reliable method of:

• Removing and eliminating wrinkles.


• Width gain.


• Separating slits in processing applications.


• Maximizing yield of finished product to raw material.

Recent research and development work by ARTech. in analysing the functional behavior of curved-axis rollers has yielded a scientific method for selecting the proper roller and the proper placement of the roller in the web process or operation. Operational performance results can now be predicted rather than using the 'rule of thumb' judgments which have been employed in the past. This reduces the trial and error process which, in many cases, has proved to be unsatisfactory, costly, and, most importantly, time consuming.

We recognize that questions will be raised for specific applications of rollers. Applied Roller Technology, Inc. stands ready to assist in providing answers to these questions.

Spreader Roller Applications

The spreader roller or curved-axis roller can be used in many applications on a given web process. The roller can be expected to cause different effects, depending on its placement within the web.

These various uses can be placed in categories such as:

• Removing wrinkles or smoothing.


• Slit separation.


• Web or material expanding on some materials.


• Weft or warp straighteners.


• Warp spacing.


• Equalize tension for webs to be coated or laminated.


• Wet felt conditioning in paper mills.


• Wet felt wash cycle.


• Etc.

All of these applications require specific bits of information that can permit the correct selection of the required roller and the method of installation.

The information necessary to define a wrinkle-removing application can only be provided by the careful examination of the existing line. Call us today for a complete assessment.
