Intermediate Rolls are used to guide, support, and maintain alignment of materials (such as paper webs) as they move between different processing stages in an industrial system. They prevent sagging, wrinkling, and misalignment, ensuring smooth and continuous production.
According to the directory, Intermediate Rolls are available in carbon steel or stainless steel. Some rolls may have a rubber or polyurethane surface coating, with a typical thickness of 3–10 mm, depending on the application.
Key specifications include roll diameter, face width, surface roughness, hardness, maximum operating speed, operating temperature, TIR, dynamic balance grade, bearing type, weight, load capacity, and coating thickness. These parameters must be matched to the specific process requirements and verified with the manufacturer.
You should consult the legal manufacturer or supplier and provide your process parameters (e.g., web width, speed, tension, temperature). They can confirm the appropriate roll specifications and relevant standards. The values listed in the directory are reference ranges and must be confirmed for the actual model.
