DEFINITION

Classification: 264/290.7

Including contact with mechanism in stretch path (e.g., snubbing, etc.):

(under subclass 290.5) Process wherein the fiber, besides contact with the two essential mechanisms which cause the tension application and define the stretch path, contacts also a third solid object arranged between the two essential mechanisms.

(1) Note. The third object often, but not always, serves the purpose of defining the necking point of the fiber during stretching.
