Summary

WrinkleSTOP® No-Bow Spreader Roller

The WrinkleSTOP^® No-Bow Spreader Roller is designed to remove wrinkles without distortion, marking, or stretching of the web. Unlike bowed or grooved rollers, it uses a smooth, straight, expanding surface that delivers extraordinary performance in wrinkle elimination across a wide range of materials. WrinkleSTOP^® is the ideal for converters in printing, laminating, films and foils, coating, and other related industries.

Works well on all types of material including:

Cloth
Paper
Foil
Film
Plastics
Nonwovens

Eliminate wrinkles without distortion, marking, or stretching. WrinkleSTOP^® is a compact, bowless roller engineered for smooth, flawless web handling. It is the only smooth surface, linear, adjustable, expanding surface roll on the market. Traditional anti-wrinkle rollers can distort webs, require extra space, or demand downtime for adjustments. WrinkleSTOP^® eliminates those challenges with its real-time adjustability while the line is running.

Easily replaces existing idler or anti-wrinkle rollers
Smooth, continuous surface will not mark or distort web during spreading
Independent adjustment of degree of spreading from both sides – adjustments can be done while the line is in motion
Straight, uncurved construction will not create increased tension in the center of the web, unlike bowed rollers
No long entry/exit spans needed – ideal for applications with space constraints
Dead shaft construction
Adjustment completed with a hex key – no special tooling required

Inside of the WrinkleSTOP^® Spreader Roller

Bowless, smooth roll produces zero-web distortion – WrinkleSTOP^® will not mark, stretch, introduce wrinkles into the web, or send non-level web into other level sensitive devices such as moisture or weight meters. This prevents stressed or torn web center areas and altered centerline travel
Independent edge-to-edge adjustability while the web is in motion – Quickly alter the degree of expansion at each end cap. This allows for distortion to be corrected at earlier points in the line and gives total control of spreading action to meet the requirements of the specific application.
No special tools needed to adjust degree of spreading action - Provides productive, cost-effective performance
Directly replaces existing anti-wrinkle rollers or idlers with easy installation
Accepts and delivers web at any angle: WrinkleSTOP^® works will with extremely short lead-in and lead-out web distances without sacrificing productivity. Saves space in your plant line, improves web runs, and allows replacement of existing limited-angle roll arrangements with fewer rolls.
Designed for high traction - Stretchable rubber sleeve maintains high traction without surface glazing
Reliable performance in a variety of conditions - Vacuum chambers, High-heat applications, corrosive atmospheres, food and pharmaceutical operations
