Ordinarily, shears were start-stop types, which began moving when the shearing point arrived. However, there was a limit to the speed of the blade rotation shearing speed because the blades went from a standstill then began rotation and acceleration. Continuous rotating shears were adopted for the HSDS system, enabling faster shearing speeds. This makes stable shearing possible at even faster rolling speeds.
