METHOD OF MAKING TYPEWRITER RIBBONS.

Application filed October 6, 1925. Serial No. 60,844.

To all whom it may concern:

Be it known that I, Howano B. VANNOTE, a citizen of the United States, anda resident of Hasbrouck Heights, in the county of Bergen and State-of New Jersey; have invented a new andv Improved ethod' of Making Typewriter Ribbons, of which the following s a full, clear, and exact description.

This invention relates to typewriter ribbons and method of making the same. An object of the invention isjto provide a typewriter ribbon having end portions which are free from ink so that the operator can readily manipulate the ends of the ribbon to place the same in operative position onat ewriter or remove the same there 7 from without soiling the fin era.

I am of course aware t at various attempts have been made to protect the operators fingers from contact with the ink of ribbons, such for example as covering the ends of the ribbon or impregnating the ends of the ribbon with chemicals or other materials to prevent the absorption of ink therein, which latter, however, do not prevent the smearing of ink on the surface of the ribbon, and it is the purpose of my invention to provide a ribbon which has ink only throughout the main portion thereof, the end portions of the'ribbon being entirely free from ink and untreated in any manner which would interfere with the flexibility of the ribbon or the proper manipulation thereof.

A further ob'ect is to provide an improved arrangement 0 steps in the method of making a ribbon such as defined all of which wil be more fully hereinafter described and pointed out in the claims.

While I shall refer to my invention as applied to typewriter ribbons it is to be understood that I use this term in its broadest possible sense to coverjan inked ribbon or strip for any analogous; urpose. t

In the accompanying-drawings? Figure l'is a erspeeti view illustrating my improved ri bon; I

Figure 2 is a plan n a very much reduced scale, illustrating the first steps in the method of making my improved ribbon;

Figure 3 is an exaggerated view in transverse section on the hue 3-3 of Figure 2. A represents my improved ribbon and B the uninked ends thereof.

In carrying out my improved method I provide a sheet. or strip 1 of suitable material of any desired width and any desired length. On this sheet or strip 1 at points corresponding to the length of the ribbon A to be made, and on both sides of the sheet or strip 1, I secure by adhesive, covering sheets 2 which prevent the assing of the ink to the strip, and I prefzrably employ non-absorbent paper or other suitable material, which may be secured to the material or sheet 1 by adhesive or otherwise.

This sheet or strip 1 is then out along longitudinal lines, as indicated by the dot and dash lines 3, cutting the same into proper widths of ribbon strips. These ribbon strips thus formed are then passed through the inkin process so that the strip becomes thorough y impregnated with ink except at the portions covered by the paper 2. At such points the paper prevents the passage of the ink to the strip. The paper is then removed and the strip out, or vice versa, so that the uninked portions are at the ends thereof.

It is to be understood that the non-absorbent material is applied only at those places where the ribbon is to be protected from receiving the ink.

It is this broad idea of providing an inking ribbon, having uninked ends free from chemicals and other impregnating or covering material, which constitutes the broad idea of my invention and I desire to cover the same broadly as well 'as the process which enables the production of such a ribbon.

I claim:

1. The herein described method of making typewriter ribbons, consisting in providing a sheet of any desired width and length, then securin by adhesive on both faces of said sheet, sieets of non-absorbent material, said sheets of non-absorbent material applied only to those portions of the sheet to be protected from receiving the ink, then cuttingv the sheet into strips, then passing the strips through the ink, then re- I eets of non-absorbent moving the material and severing the strips into lengths. I

2, The herein described method of making t writer ribbons, consisting in securing aper to opposite faees of the material 0 the ribbon sections, said sheets of non-absorbent material applied only to those portions of the ribbon passin the through the ink to impregnate e strip with the ink, the paper serve ing to retain all of the ink to which that portion of. the ribbon covered thereby is subjected then removi' the paper and s eparating'the stri s into en hs.
