multi-part ribbon and method of making the same . ^ |

The invention relates to printing or typewriter ribbons for typewriters, calculating or printing similar machines and brings a new two-piece or two-colored, possibly multi-colored tape of this type.

One of the biggest problems in the production of multi-color bands of the above type lies in the requirement that different marking or color components or regions from each other to be kept separate to isolate or _e. In the most famous case of a black-eot-typewriter-color | tape, for example, the two half-width longitudinal strips of a single G-ewebebandes are individually, ie each individually, soaked with a dye of the corresponding color; any capillary or similar transition or crossing of one color into the other colored stripe would result in the destruction of the colors and thus the usability. It is therefore necessary, some

impenetrable separation barrier along provide the parting line between the strips and soak the two tissue portions independently with the respectively associated color or colors with enemy, d "h _o a mutual repulsion causing properties to use" The required method steps are critical, difficult and expensive} the entire process is nothing short of error-free; it is unreliable and results in large scrap, that is, a significant percentage of unusable or bad ribbons. The difficulties of the process also place certain limits on the type of colors used; for example, the color intensities that can be achieved are limited

The invention relates to the production of multi-part or multi-colored tapes of the types mentioned at the beginning Kind with improved qualities, in particular with compared to hitherto much more favorable properties both for the Storage as well as for use; it also relates to an improved manufacturing process in which any Risk of mutual mixing or exudation ("bleeding") of the colors or inks is absolute is avoided. In a preferred embodiment of the invention, the color bears produced are similar in one relationship a known type of single-colored ribbons, namely those ribbons in which a color impermeable plastic or plastic membrane or layer (film) is provided which covers the non-printing side or surface

of the ribbon covered and applied along the longitudinal edges or edges of the ribbon, so about through Heat is attached (fused, welded), so that the keeping of the print types is improved and a greater color storage capacity is guaranteed.

Generally speaking, the invention completely frees the process of making multi-part tapes from the previous ones Restrictions, such as those due to the properties of the paint, the type or sequence of the work steps for soaking the paint (Coloring) and given by the various specific ^ details of 4 coloring machines "

The ribbon according to the invention consists of two independent fabric or similar strips (longitudinal ribbon strips), which together have the width of a conventional ribbon (the sum of the widths of both strips is equal to the 'usual ribbon overall width)} these two mutually parallel strips are in or _e along their common line of contact by a plastic (deformable), heat-sealed, -verschmolzene or -verschweißte and color-insulating compound, such as an edge or a (z, B. drahtar.i ^ e ^ iiaht connected. This Haht formed by simultaneously cutting and Seam welding (continuous "line re-welding") of two superimposed strips along their common center line; each of the separate halves of this "sandwich" thus results in a composite strip with independent, but connected elongated sections or areas (longitudinal strips) .These are then separated, ie, individually with Dyes of the corresponding colors

These two layers, placed one on top of the other, but not connected, are guided over a suitable support, such as a roller, like a "sandwich" and cut into several narrow strips 18 by means of sharp knives or circular knives (circular knives) 16! they are kept at a sufficiently high temperature.

hold, so that the substances are connected (welded) to one another at the separating edges of the resulting ribbon strips 18. One of the finished ribbons is shown in FIG. It consists of the fabric layer 10 and the overlying loose plastic lamina or layer or the plastic film 12 (for example, _e plastic film); the two layers or plies are fused to one another (welded or similarly connected) along their common (lateral) longitudinal edges, for example at 20 and 22.

As already mentioned, the be-P written type are already known, the description has only been given so far as is necessary for a clear understanding of the present Invention is required «

To now, for example, a two-tone according to the invention To produce ink ribbon, two of the independent ribbons shown in FIG. 2 are placed one on top of the other (FIG. 3). The G-ewebeteile 10 and 10 'of these bands can already with corresponding Paints or equivalent substances, which have or contain the desired colors, have been soaked. However, as will be shown later, one band or both bands in the as yet unpregnated state can or can also be used in this case Work step can be used "Even if the tapes are already soaked, the plastic separating layers 12, 12 'prevent any unwanted transfer or migration of the impregnating substances in this process stage. The superimposed according to FIG Ribbons are shown slightly separated (closely spaced from one another) for the sake of illustration «In practice, however are they kept in contact with each other, especially during the next stage of the process "

Fig. 4 shows this next stage of the method according to the invention; the upper band of Fig. 3 (and Fig. 4) is provided with the reference symbol "R ⁿ , for example to indicate that its fabric layer is or is to be soaked with a red printing ink. The lower of the two bands is similar with the letter "B ^w (= Black) for black. This Fig. 4 illustrates how the superimposed strips are simultaneously separated (cut lengthways) along their longitudinal center line, for example by means of a heated knife (circular knife) 24, which works together with a counter support such as a λ washer plate (table top) or a roller 26 this process is carried out in a manner as illustrated in Fig. 1, wherein the heated knife 24 is stationary or a sharp-edged disc or roller, i.e. a rotatable circular knife is between the knife 24 and the base or counter support 26, the superimposed strips R and B passed through. During the cutting process, the heated knives 24 simultaneously fuse the edges that are adjacent to them and each on one side of the cutting or dividing plane (i.e. the cutting edges of the right half of the knife 24 in FIG from the knife 24 lying half of B welded together t).

now in longitudinal connection with the underlying half of the 'black band B. At the same time, the two areas, which form the left (newly created) band in Fig. 5, with a continuous weld or fusion line has been provided, which is an impenetrable barrier against any migration of dyes or other impregnating agents (i.e. against any transition from one color to the other) that affects the adjacent halves of the tissue had been applied or “still need to be applied. The right (newly created) band is in the same way with a fused or similar connection 30, that is to say for example a weld seam preventing the change in color been.

Fig. 6 illustrates how the two bands according to 'Fig. look like they have been completely spread apart and laid flat. The two (newly created) bands are adjacent to each other shown at only a small horizontal distance, analogous and corresponding to FIG. 5. It is readily clear that the two independent two-part (newly created) color ribbons, as they are through the process according to Figo are produced on completely separate paths to suitable guide and winding mechanisms as is customary in the manufacture of ribbons · In all drawings, the thickness of the ribbon components is exaggerated for the sake of clarity

If the two superimposed strips of FIG. 3, in particular their tissue parts, which have not already been soaked with their corresponding colors, are of course the ones

Tissue parts of the (newly created) tapes "RB" and "RB" shown in FIG. 6 are still unimpregnated. The fused by means of heat or welded midline region 28,30 (Figure "6) each • band allows to apply to both sides of the center seam dyes without any risk of mixing accordingly or" on these tapes mono- or _"e Undesired mixing may either within of the belt still take place between the different parts of the impregnation device. For example, the impregnating substance can be safely applied to the corresponding tissue parts by means of devices that are completely separated from one another and arranged along the conveyor belt direction.

Since the production of multi-colored ribbons by means of this process is single-colored or even not impregnated Tapes with full width (normal width) as the starting material used, the requirements for any combination of different colors can easily by means of a minimum stored, finished monochrome ribbons are fulfilled (relatively low supply or storage requirements). Also brings that inventive method complete liberation from all Limitations previously imposed by the known dyeing processes, dyes and equipment or devices.

It should be noted that any of the tapes made by the method described above has the advantage that it is composed of lamellar one-piece strips, specifically as shown in FIG Ribbons according to Fig. 2 are obtained by severing). Both appropriately and differently colored or impregnated ribbon stripes are each with a plastic layer or

Provided lamella, which keeps the printing or typewriter clean, an improved ink storage capacity and ensure a long service life.

It does not speak a serious reason, however, that the two bands shown in Figo 3, superimposed (in the method) can be reversed, d _e h that they touch with their fusible (weldable) fabric pieces 10,10 '. This is particularly possible if the tissue parts are not yet soaked in this state. Such a variant is of course within the scope of the invention - it is no longer recognizable in the finished product after the strips have been unfolded and leveled (the finished product is identical to the one that is produced without using the variant.

The method described above is generally applicable where a color or impregnation substance-separation barrier between two strips of tape is required, not only to migration of color from one stripe to the adjacent strips or _e differently colored in its or different layer or impregnation, but also to prevent the color from migrating into the material of the other strip. For example, a two-part tape can carry a printing ink in one of its longitudinal stripes, and its other stripe can be coated with a transferable cover material (camouflage), which results in a combined printing and error-correcting tape for typewriters or the like. (Camouflage = correcting printing or typing errors by applying and "sticking", for example, white covering color onto the wrong, ie incorrectly printed or typed letters on the writing paper) η ORIGINAL ~ ^Β1βΐΐ 11 -
