What are Spreader Rolls?
Spreader rolls usually consist of a rigid, curved shaft around which sleeve segments mounted on precision roller bearings rotate. The segments can be made of steel or stainless steel materials, and the surfaces - depending on the area of application - can be of a wide variety of textures: smooth, coated (e.g., chrome), or with a structure (e.g., grooved/rifled) or rubberized or silicone-sleeved. Between the sleeves, there are application-specific protection and sealing systems that prevent moisture and contaminants from entering the roll.
The spreading effect is created by the tendency of the paper web to run in and out at right angles to the spreader roll. The roll curvature causes a lateral deflection of the paper web and, consequently, a transverse stretching of the material.

Use of Spreader Rolls in Paper Manufacturing
Spreader rolls are used at various points in the paper manufacturing process, both in the wet and dry sections. Their main task is to guide the paper web without wrinkles and to keep the transverse stretching constant. This ensures that the paper web runs straight through the machine and achieves a consistently high production quality.
Depending on the position of use in the paper machine, different versions of spreader rolls are used:
- for wet and dry sections
- with fixed or variable curve
- with different materials and surface designs
