Flex Cut VS Crush/Score Cut
Crush or score cutting uses a semi sharp circular blade that is pneumatically loaded against a hardened anvil roll. The blade crushes the fibers and causes the fabric to split. Since it crushes the fibers and does not shear them, it tends to leave some fuzz on the edge of the material. It works the same way a pizza cutter works.
Advantages of Crush/Score Cut:
Less expensive to set up and operate
Use of thin knife enables knife holders to be mounted close together for cutting narrow strips of material.
Blades can be quickly changed when they become dull.
Important note: Blades must be sharpened properly, not to a razor sharp point, but rather to a rounded point with a specific radius.
