A TTORNEYS.
THREE COMPONENT PRTNTING RIBBON AND METHOD OF MAKING SAME The invention is directed to a printing ribbon which is to be wound on spools for use in machines such as typewriters, computers, bank record machines, etc.
The ribbon has three components including first and second ribbon portions which are different from each other and interconnected by an uninked connector strip. The connector strip is preferably welded to each of the first and second portions by a weld disposed along a bias. The bias of the weld is preferably a 45 angle.
The first and second ribbon portions may differ from each other by details of construction. For example, one ribbon portion may be a conventional printing ribbon and the other may be a strip of correction material such as the correction material designated as layer 22 in U.S. Pat. No. 3,273,686. For a conventional printing ribbon which is preferably made from nylon, see U.S. Pat. No. 3,010,559. Alternatively, the first and second portions of the ribbon may differ from one another only in the color of the ink or other printing medium on each portion. Each of the first and second portions need not be inked completely from a single color, but may be inked with dual colors.
The connector strip may be a layer of nylon plastic film. Preferably, the connector strip is a sandwich of uninked nylon fabric between layers of nylonfilm with the layers being welded along their longitudinally extending side edges. The sandwich construction is preferred so as to be opaque and thereby facilitate ease of distinguishing between the ribbon portions. A trademark, installation instructions, or other information may be printed on the connector strip. The connector strip is preferably located at the center of the ribbon so that it will be'the portion grasped by the fingers when installing the ribbon without soiling ones fingers. A connector strip prevents migration of the ink or printing medium from one portion of the ribbon to the other. The connector strip is preferably of a sufficient length so that it may completely wrap around one portion of the ribbon wound on the spool and thereby prevent contact between the portions when they are wound on the same spool. I
It is an object of the present invention to provide a novel printing ribbon.
It is another object of the present invention to provide a novel printing ribbon having two differently constructed portions interconnected by a connector strip.
It is another object of the present invention to provide a more versatile printing ribbon having two differently inked portions interconnected by an uninked connector strip.
It is another object of the present invention to provide a printing ribbon having an uninked connector strip substantially at the center thereof to prevent soiling fingers when installing the ribbon.
it is another object of the present invention to provide a novel method of making a printing ribbon.
It is another object of the present invention to provide a novel method of making a printing ribbon from two differently constructed portions in a simple, reliable and inexpensive manner.
Other objects will appear hereinafter.
For the purpose of illustrating the invention, there is shown in the drawing a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.
FIG. 1 is a perspective view of a printing ribbon in accordance with the present invention wound on spools.
FIG. 2 is a perspective view of apparatus used in making the printing ribbon of the present invention.
FIG. 3 is a sectional view taken along the line 33 in FIG. 1.
Referring to the drawing in detail, wherein like numerals indicate like elements, there is shown in FIG. 1 a printing ribbon designated generally as 10. The ribbon 10 includes a first ribbon portion 12 wound on spool 14 and a second ribbon portion 16 wound on spool 18. One end of ribbon portion 12 is secured to its spool 14. One end of ribbon portion 16 is secured to its spool 18. The free ends of the ribbon portions 12 and 14 are interconnected by a connector strip 20.
The connector strip 20, if desired, may have a grommet 22 attached thereto to designate the center of the ribbon 10. The ribbon portion 12 differs from the ribbon portion 16. For purposes of disclosure, these ribbon portions 12 and 16 differ from one another in the color of ink or printing medium applied thereto. For example, ribbon portion 12 is comprised of longitudinally extending strips 24 and 26 which are inked with different colors separated by the barrier 28.
The barrier 28 may be a mechanical barrier such as that disclosed in U. S. Pat. No. 3,274,039. Alternatively, the barrier 28 may be a normal barrier attained when strip 24 is inked with a color red and strip 26 is inked with a color black, using repelling inks which do not migrate into one another. In a similar manner, the strips 32 and 34 may be colored blue and green respectively with the barrier 36 preventing migration of the different colored inks.
The connector strip 20 is joined at one end to ribbon portion 12 by a butt weld 30. Weld 30 is disposed at a bias of approximately 45 with respect to the side edges of the ribbon 10. The other end of the connector strip 20 is joined to the ribbon portion 16 by means of weld 38. Weld 38 is likewise disposed at a bias of approximately'45 with respect to the side edges of the ribbon 10. It will be noted that the welds 30 and 38 converge.
As shown more clearly in FIG. 3, the connector strip 20 is preferably a sandwich comprised of uninked fabric 40 between layers of film 42 and 44. The combined thickness of the layers 40, 42, and 44 of the sandwich forming the connector strip 20 preferably correspond approximately to the thickness of the ribbon portions 12 and 16. The fabric 40 is preferably one which can be welded, and therefore is preferably nylon. The film layers 42 and 44 are also preferably nylon film having their longitudinally extending side edges welded to the longitudinally extending side edges of the fabric 40. The connector strip 20 preferably has a length which is slightly greater than the diameter of the ribbon portion 12 when it is wound on spool 14 or the ribbon portion 16 when it is wound on spool 18. In this manner, the connector strip 20' will prevent migration of ink or printing medium from ribbon portion 12 to ribbon portion 16 when they are wound on the same spool. Typically, connector strip 20 will have a length of approximately 6 inches.
In FIG. 2, there is shown apparatus as used in the present invention. As shown therein, reels 46 and 48 are mounted on a shaft 50 for rotation therewith in the direction of rotation indicated in FIG. 2. Reels 52 and 54 are mounted on shaft 56 for rotation in the direction thereof as indicated in FIG. 2. The reels 46, 48, 52 and 54 are preferably adjustable along the length of their respective shafts 50 and 56 so that they may be aligned with one another as indicated in P16. 2.
The ribbon material 12' wound on reel 46 corresponds to the ribbon portion 12. The ribbon material 12' is to be unwound from reel 46 and wound on reel 52.
The ribbon material 16' corresponds to the ribbon portion 16. The ribbon material 16' is wound on reel 48. As the material 16' is unwound from reel 48 it is wound onto reel 54. The distance between adjacent reels 46, 48, 52 and 54 on the shafts 50 and 56 is selected so as to correspond generally to the desired length of the connector strip 20.
Ribbon material 20' is wound on spool 58. Spool 58 is attached to shaft 60 which rotates in a direction indicated in FIG. 2. When a sufficient or desired amount of the materials 12' and 16' have been wound on the reels 52 and 54 respectively, rotation of the shafts 50 and 56 is terminated. Thereafter, the material 20' is unwound from spool 58 so that it overlies the ribbon materials 12' and 16' is shown in FIG. 2. Thereafter, a cut is made with a heated knife along the lines designated AB and CD. This cutting action severs the connector strip 20 from the ribbon material 20', severs the ribbon portion 12 from the ribbon material 12', severs the ribbon portion 16 from the ribbon material 16', and simultaneously welds the ends of the connector strip 20 to the free ends of the ribbon portions 12 and 14. In this manner, the ribbon that is produced is wound on a pair of reels wherein reels 52 and 54 would correspond to spools 14 and 18 respectively.
As soon as the reels 52 and 54 are removed from the shaft 56, replacement reels may be added thereto so that the process may be repeated. in repeating the process, the free end of ribbon material 12' is secured to the replacement reel aligned therewith. Also, the free end of ribbon material 16' is attached to the replacement reel aligned therewith. Reel 46 preferably contains ribbon 12' of nylon fabric inch wide and reel 48 preferably contains similar ribbon material 16 of the same width. The ribbon material 20 has a width corresponding to the width of the ribbon materials 12' and 16. After the cutting action along the lines AB and CD, the free ends of the ribbon materials l2, l6 and 20, may be squared. That is, the ribbon materials 12, 16' and 20 are cut transversely and any portion of the ribbon materials 12', and 16' and 20' which were joined together when said cutting action occurred along lines A, B, and C, D are discarded.
The cutting of the material 12', 16 and 20' along lines AB and CD may be accomplished by heated knives, heated wires, or other conventional devices well know to those skilled in the art. Hence, the structure of such knives or heated wires are not described in detail.
While nylon is the preferred material referred to above, other materials capable of being welded may be used. Thus, portions 12 and 16, and fabric 40 may be made from Dacron, while the layers of films 42 and 44 may be made of Mylar. If desired, portions 13 and 16 may be provided with a protective film welded only to the side edges thereof as disclosed in U. S. Pat. No. 3,010,559 to prevent direct contact between a type bar and the printing medium on the ribbon portions 12 and 16. The lack of such direct contact eliminates the need for cleaning the printing key. The printing portions 12 and 16 and the connector strip 20 are each flexible and pliable so that they may be wound on spools and used in the machines referred to above.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
