DEFINITION

Classification: 425/200

(under the class definition) Apparatus including means ahead of a former for agitation, mixing, blending or kneading material to be shaped.

(1) Note. Disclosure of apparatus for kneading of the material simultaneously with shaping into the desired shape, e.g.., as in "balling" dough into loaves, are not included under this definition. However, where such apparatus is combined with separate shaping means, the patent is included herein, e.g.., kneading means downstream or upstream of sheeting means.

(2) Note. Milling means in combination with the shaping or extrusion means are included within the scope of "agitating or kneading means" and are classified within this subclass or appropriate indented subclass.
