2.1.4.2. Carriage Cut Off
This application is typically cutting strip material such as steel into pre-set lengths
by means of a Flying Shear (heavy-duty knife mounted on a moving carriage).
The shear must be stationary relative to the material (for example, moving at line
speed) when the cut is made and the cut takes a fixed time.
Strip material is unwound from a reel at constant surface speed and fed via
separately driven leveler rolls. After the cut is complete, the shear is stopped then
moved back to its start position. It must accelerate to match the line speed at the
correct position to cut the required length of material.
