What is difference between fly shear cut-to-length line and traditional stop cut-to-length line?

Fly Shear - Coils are shear under continuous running status. The shearing systems are controlled by PLC (Programmable Logic Controller) in order to make shearing speed the same (or similar) as coils running speed.

Stop Shearing - Coils are shear under stop status.

Fly shear cut to length line has better production efficiency than stop shear cut to length line. Also, fly shear can reduce roller mark on surface finish.
