Title:
Shaver inner cutter
Abstract:
A landless inner cutter having a body portion which is made from a single piece of metallic material such as a flat strip of sheet metal. The inner cutter has a body portion including a pair of longitudinal flanges provided with ledges which support a plurality of parallel, arch-shaped, cutter tooth blade sections. The blade sections span the space between the flanges and are disposed normal to the same. In addition, the inner cutter includes a support which is also made of a single piece of sheet metal, to which the blade sections are individually secured so as to rigidly maintain the same parallel to one another. The blade sections are formed in a flat strip of sheet metal in order to form a landless inner cutter. Material if formed from the strip to provide the same with a first archlike edge which has a rise and a span. A second archlike edge is formed in the strip which is longitudinally displaced from the first edge such that the span of the second edge intersects the rise of the first edge. Bending the resulting arch-shaped strip material or blade section out of and normal to the plane of the strip, provides a normally disposed, arch-shaped blade section. Successive repetition of the cutting and bending provides a plurality of equidistantly-spaced blade sections in the strip.
