DEFINITION

Classification: 299/40.1

Freely rolling cutter:

(under subclass 39.1) Rotary cutter in which the breaking up device is caused to move about an axis while in rolling contact with the bottom surface, due to the translation of the axis over the bottom surface rather than due to means driving the breaking up device about the axis.
