DEFINITION

Classification: 72/183

By tension applied to work or product (e.g., uncoiling):

(under subclass 127) Subject matter wherein the instrumentality comprises means for applying a tensile stress to the work during deformation.

(1) Note. This subclass includes patents disclosing the

straightening of coiled metal by pulling on the free end thereof with a force sufficient to uncoil and deform the metal.
