The cutting blade includes two sets of rollers bearing against one of a pair of profiled side surfaces of the axial actuator rod.
Claims5
A metal strip cutting apparatus for use with a metal strip, comprising:
- two rotatable drums each having a cutting blade and an axial actuator rod, the two rotatable drums being arranged side-by-side so that said metal strip passes between said two rotatable drums;
- each axial actuator rod having a pair of profiled side surfaces and being disposed within the corresponding rotatable drum;
- each cutting blade including two sets of rollers, each set of rollers bearing against one of said pair of profiled side surfaces of said axial actuator rod, said pair of profiled side surfaces disposed between said two sets of rollers;
- and
- wherein each axial actuator rod is adapted to move each cutting blade between a retracted position in which said metal strip passes freely between said rotatable drums and an extended position in which said cutting blades cut said metal strip.
