Summary

Bottom anvils with multiple grooves for slitting applications

• Free locking - anvils are locked by the knife shaft, typically an air expanding strip shaft.
• Set screw locking - a set screw fixes the rotation of the anvil on a hardened shaft.
• Multilock - Using a single grub screw, a flexible element tightens the multilock ring concentrically around the knife shaft eliminating problems with runout caused by set screw mounting.
