Breast Roll
The Breast Roll is one of the most important rolls in the forming section of a paper machine line. Located near the headbox at the beginning of the wire section, mainly to supports the forming fabric and helps create the correct path and tension for sheet formation. Its accuracy directly influences the stability of the forming process and the quality of the paper sheet.
A well-manufactured breast roll could help maintain uniform fabric running, stable web formation, and proper drainage conditions in the early stage of papermaking. Its design requires excellent concentricity, surface precision, and dynamic balance to minimize vibration and ensure smooth operation at high machine speeds.
Breast rolls are commonly produced in carbon steel, stainless steel, or alloy steel, with optional surface coatings depending on the machine environment. As a critical support roll in the forming section, the breast roll is essential for paper quality, machine stability, and long-term operating efficiency.
