DEFINITION

Classification: 264/210.1

And reshaping:

(under subclass 176) Process which includes the additional step of stretching or permanently reshaping the formed article.

(1) Note. Classification of patents in this and indented subclasses. Patents should not be cross-referenced to this or its indented subclasses on the basis of disclosure, unless an unusual feature of the extrusion step or an unusual interrelationship between the extrusion and reforming steps is disclosed. Subclasses 239+ provide more specifically for molding and reshaping operations and are the preferred loci for such disclosures.

138+, for a process wherein stretching causes a tearing of the workpiece.

154, for pore formation due to stretching. 168, for crimping or crinkling of indefinite length articles.

181, for stretching of indefinite length articles in liquid in motion.

197, and 198, for stretching or deforming of indefinite length viscose articles.

208, for stretching of cellulose derivative articles formed by extrusion and solvent evaporation.
