DEFINITION

Classification: 226/55

(under subclass 52) Device in which said prong contacts the variations periodically to hold said material against motion in any of (1) a forward direction or (2) a rearward direction or (3) both directions.

(1) Note. The prong of the patent placed herein may produce movement of the material either forwardly or rearwardly of normal travel, by reason of the shape of the prong and/or movement thereof, as it engages the variation to effect registration of the material. However, such additional material movement is deemed to be incidental since no material movement takes place if the material is properly located when the prong engages the variation.

(2) Note. See (1) Note of subclass 2 for further discussion of "registration".
