DEFINITION

Classification: 241/230

(under subclass 227) Apparatus provided with means for adjustably or yieldably mounting one or both of the rotary surfaces.

(1) Note. See the reference to "Search Class" under subclasses 221 and 227, for other classes providing for adjustably or yieldably mounted roll members.
