DEFINITION

Classification: 264/622

Unconfined drawing or extending of plastic mass to form article:

(under subclass 621) Process wherein the article is formed by the free and unconfined pulling out of a plastic mass.

(1) Note. The surface configuration of the article formed is imparted solely by the extension and not by coaction of the plastic mass with a shape imparting mold surface.

(2) Note. Kneading or mulling operations, per se, (e.g., taffy pulling type, etc.) are not included herein since a shaped article is not produced. See subclass 349 and the notes thereto for such subject matter.
