(under the class definition) Device provided with means to
bend the material laterally* within its elastic limit to facilitate the moving thereof.
(1) Note. To be placed here as an original, a patent must positively recite that the bending in some way significantly alters or enhances the operation of the advancer thereon. Thus, for example, a patent claim reciting a shaped roller or guideway which bends the material into an arcuate cross-section will be placed herein only if the purpose is stated to be for stiffening the material to make the material self-supporting.
(2) Note. Longitudinal bending is not considered to be significant for this subclass.
