DEFINITION

Classification: 366/69

RUBBER OR HEAVY PLASTIC WORKING:

(under the class definition) Apparatus and method including a mixing chamber and an agitator therein for use in kneading substantially self-sustaining, semisolid, or heavy plastic

material such as clay, dough, gum, plastic, resin, or similar heavy plastic.

(1) Note. A patent for apparatus or method for mixing ingredients for making a plastic mass and kneading the mass will be placed in this or an indented subclass. However, an apparatus or method for mixing the ingredients without further kneading the mass will be placed in an appropriate subclass elsewhere in this class.

(2) Note. In regard to the line between Class 241 and Class 366, see search note to Class 366 under Class 241 definition, section 12.

(3) Note. Kneading is a process to work substantially self-sustaining, semisolid, or heavy plastic material into a uniform mixture by pressing, folding, and stretching.
