[0002] In the longitudinal shearing production line of silicon steel sheets, a tensioning device is usually provided to ensure that the core sheets maintain continuous tension throughout the production line. For the tensioning device, although the most common method is to apply a certain amount of frictional force to the core sheets, and for this reason, the tensioning device is also called a braking and pressing device. Various tensioning devices use their respective technical means to achieve the purpose of applying frictional force to the core sheets. Summary of the Invention
