As a core device at the front end of the cold roll forming line, it is used to carry and unroll metal coils (such as SPCC, SPHC, SGCC, etc.). It provides stable tension through hydraulic or mechanical systems to ensure the coil is fed into the production line smoothly without slipping, wrinkling, or loosening, laying a foundation for subsequent leveling and forming processes.
The Uncoiler is a core component positioned at the front end of a cold roll forming production line. Its primary function is to carry and unroll metal coils such as SPCC, SPHC, SGCC, SUS, and aluminum sheets, ensuring continuous and stable feeding for subsequent processing stages.
Using hydraulic or mechanical tension control, the uncoiler maintains precise tension during operation to prevent slipping, wrinkling, or material loosening. This stability ensures the coil is smoothly fed into the leveling and forming units, providing a solid foundation for high-quality and precise roll forming results.
Built with a heavy-duty structure, adjustable tension system, and high load-bearing capability, the uncoiler delivers consistent performance even under demanding production conditions. It integrates seamlessly with various forming lines, supporting efficient coil handling, operator safety, and long-term reliability in industrial manufacturing environments.
