Cutting apparatuses

A cutting apparatus comprising:

• a drive shaft having a longitudinal axis;
• a drum configured to orbit about the longitudinal axis when driven by the drive shaft;
• a first actuator;
• and
• a cutting assembly joined to the drum and configured to orbit about the longitudinal axis with the drum, the cutting assembly comprising:
• a second actuator operably engaged with a portion of the cutting assembly;
• and
• a cutting device driven by the second actuator, wherein the second actuator is configured to rotate the cutting device at least 1,500 revolutions per minute during cutting of an article, and wherein the first actuator is operably engaged with a portion of the cutting assembly and is configured to reciprocate the cutting device in directions substantially parallel to the longitudinal axis as the cutting assembly orbits the longitudinal axis.

A cutting apparatus comprising:

• a drive shaft having a longitudinal axis;
• a drum configured to orbit about the longitudinal axis when driven by the drive shaft;
• a barrel cam positioned at least partially intermediate the drive shaft and a portion of the drum, wherein the barrel cam comprises a track that forms a path that surrounds the longitudinal axis, and wherein the drum and the drive shaft rotate relative to the barrel cam;
• and
• a cutting assembly joined to the drum and configured to orbit about the longitudinal axis with the drum, the cutting assembly comprising:
• a rack comprising a first end and a second end, wherein the rack extends in a direction substantially parallel to the longitudinal axis between the first end and the second end;
• a compounding gear assembly comprising:
• a plurality of gears comprising a first gear operably engaged with the rack, wherein the first gear is configured to travel at least partially intermediate the first end and the second end of the rack;
• a cutting device driven by the plurality of gears, wherein the cutting device rotates faster than first gear;
• and
• a cam follower at least partially engaged with the track and configured to orbit about the longitudinal axis within the path of the track, wherein the cam follower is configured to move the first gear at least partially intermediate the first end and the second end of the rack when the cutting assembly is orbiting about the longitudinal axis to cause the cutting device to translate substantially parallel to the longitudinal axis.
