DEFINITION

Classification: 72/205

Including tautening of work during deformation (e.g., "tension bridle"):

(under subclass 199) Subject matter including means specifically disclosed as applying a force tending to elongate the work.

(1) Note. To be included herein, a patent must specifically disclose that the work is placed under tension; for example, by pulling the work through a deforming station, or by retarding the movement of work to a deforming station, or by exerting force sufficient to stretch or elongate the work.

(2) Note. Included herein are disclosures known as "bridling apparatus" or "tension bridle" means, wherein the work passes over one roll and under another roll in an undulant path similar to that found in the disclosures of subclasses 160+ and then passes to the bite of a roller couple. In this subclass, however, the metal is not stressed by such rolls acting alone; instead, the movement of the work is retarded by reason of the flexing produced thereby (and other factors), whereby that portion of the work lying between the bridle and a "downstream" roller-couple is tautened and deformed.
