a corporation of North Carolina Filed Mar. 9, 19ml, Ser. No. 13,8% Claims. (Cl. iig-59) This invention relates to the striping of the insulating coating of wire conductors and cables and consists more particularly in new and useful improvements in a method for applying an identifying stripe to a wire coating of polyethylene or the like, by bonding to said coating at the time of the extrusion process, a separate filament of similar or compatible material.

In the manufacture of cables used in the communications iield for example, the cable is usually composed of a series of insulated conductors and because of the large number of similar conductors contained within a single cable, it is necessary to identify individual conductors or groups of conductors embodied in the cable. Conventionally, two basic methods of conductor striping have been used, namely the ink striping method and the method wherein two or more extruders are utilized, each containing plastic materials of the desired color.

ln the ink striping method, a stripe of colored ink is lapplied to the wire by means of a wheel ruiming in an ink bath and transferring the ink to the surface of the wire coating against which the wheel is pressed, the passage of the wire causing the wheel to turn. An alternate ink striping method employs a hypodermic needle which rests against the surface of the running wire and ink is forced through the hypodermic needle onto the coating.

The ink striping method has presented several diiicult problems, both during manufacture and during use of the end product. The ink must have a precisely controlled viscosity to enable it to be carried by the printing wheel to the wire coating and to enable it to be transferred to the wire coating in a sharp, delineated stripe. lf the ink is too thin, it will run on the surface of the Wire, making an uneven blurred stripe. lf it is too thick, the wheel will transfer an excess amount of ink and it will smear on the surface of the wire. The viscosity is controlled by the addition of a thinner to the ink solution and depends entirely on the operators ability to judge the amount of thinner required.

After the ink is on the wire, it must be dried before it can be taken over a sheave or wound on a reel. This is done by passing the wire through a heated tube and the speed at which the ink can be dried determines the production rate and usually restricts high speed processing. ln the case of a hypodermic needle applicator, the viscosity and homogeneity of the ink is even more critical since the needle is so easily clogged.

Perhaps the most diicult problem with ink striping is obtaining -a bond between the ink and the plastic coating on the wire. With polyvinyl chloride insulation, a reasonably good bond can be obtained, but with polyethylene insulation which is now largely in use, it is impossible to obtain a good bond. A poor bond between the ink stripe and the insulation results in aking of the ink from the insulation during further processing of the wire and in handling the wire in the field. .Flaking of the inl: or loss of the ink on the surface due to abrasion results in loss of ability to identify a wire by its colored tate latent @free 3,076,235 Patented Feb. 5, 1953 ductor coating, it is impossible to put enough red pigment in an ink to completely mask the black coloring under the ink. The result, of course, is a stripe with a washed out appearance which can result in erroneous identification of the wire.

The other method of striping which utilizes the two or more extruders containing different colored plastic materials, involves apparatus wherein the eXtruders force the plastic materials through a common orice through which the wire is running, forming an insulating coating on the wire. The colors of this coating correspond to the colors in each of the extruders. The most serious objection to this type of striping is the fact that color changes require the disassembly and cleaning out of one or more of the eXtruders which is a time consuming operation.

lt is therefore the primary object of the present invention to overcome the above-noted difficulties and to provide a method for applying a preformed monofilament to an extruded wire coating, the material of said monolament being similar to or compatible with that of the plastic coating on the wire and wherein the stripe is pressed into the still hot plastic coating on the wire at a point irnmediately posterior to the extruder die orifice.

Another object of the invention is to provide a method of this character wherein a monofilament stripe is applied to the wire coating while the latter is still hot, whereby, since the material of the monoiilament and the plastic wire covering are similar, the material in the monotllament softens and forms a very effective heat sealed bond to the plastic wire covering.

A further object of the invention is to provide a method lfor applying a monofilarnent stripe to a wire coating with a heat sealed bond to thereby avoid flaking and, since the monolament is embedded deeply in the insulation, any abrasion great enough to remove the monolament stripe would completely destroy the insulation.

Still another object of the invention is to provide a method of this character wherein no solvents or thinners are required and bonding occurs so quickly that no practical limit of processing speed exists and the thickness of the monolilament permits sharp, clear contrast between the stripe co-lor and the background color of the Wire coating.

A marked advantage of the present invention resides in the fact that the monollament need not be completely embedded in the conductor insulation, but can be permitted to protrude above the surface of the insulation, creating in effect a raised ridge along the surface of the conductor insulation, thus enabling the stripe to be felt as well as seen for use in identifying striped conductors from plain conductors.

A still further object of the invention is to provide a method for applying a monolament stripe to a wire coating wherein the stripe colors, when applied to a common background color, can be changed without stopping the process, resulting in an obvious saving in time and scrap material.

With the above and other objects in View which will appear as the description proceeds, the invention consists in the novel features herein set forth, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

Referring to the drawings in which numerals of like character designate similar parts throughout the several views:

FlG. l is a diagrammatic view illustrating the apparatus of the invention in side elevation;

FIG. 2 is an enlarged detail of the striping device in side elevation;

HG. 3 is an edge view of the striping device shown in FlG. 2;

FIG. 4 is Ian enlarged transverse sectional view of a coated wire with an embedded stripe; and

FIG. 5 is Ia similar view showing a raised stripe or rib.

In the drawings, referring first to FIG. l, 6 represents a conventional Wire payoff reel from which conductor wire 7 is fed through a suitable electric preheater or the like 8, to the extruder die 9 of a conventional extruding device 10. The material for providing the insulating coating for the wire 7, preferably polyethylene, is fed in heated condition, to the extrusion die 9 from reservoir 11, and as the wire passes through the orifice of the extruder die 9, it is coated 4with polyethylene in the usual manner. Y

As the coated wire leaves the extiuder orifice 9 and while it is still hot, a preformed monofilament 12 of polyethylene `is applied to the coating by means of a striping roller 13, said monofilament being fed from a payoff reel 14 carried by a 4suitable support 15. The filament 12, while preferably of polyethylene, may be of other compatible material and of any desired color.

Turning to FIGS. 2 and 3 which illustrate the striping device more in detail, the roller 13 is rotatably supported -by a bifurcated yoke 16 suspended from a threaded stem 17 which is vertically adjustable in a complementary threaded opening in a holding bracket 18 supported posterior to the extruder 9. The threaded stem 17 extends through the bracket 18 and, fixed to its upper end, is an adjusting knob 19 whereby the position of the roller 13 with respect to the coated Wire 7 may be adjusted and the pressure of the peripheral engagement of the roller with the wire may be controlled. A knurled lock nut 20 is preferably provided for maintaining aselected vertical position of the roller 13.

Preferably the periphery of the roller 13 is grooved as at 21 to embrace the coated wire 7 immediately after it leaves the orifice of the extruder 9 and in order to present the filament 12 in the center of the wire, a supplemental groove 22 is provided at the base of the main groove 21. As best seen in FIGURES 2 and 3, the groove 21 is of a width and depth to substantially centrally receive the strand of filament 12 and simultaneously directly engage the peripheral coating 7a of the wire 7, on either side of the filament. Thus, as the hot coated wire 7 advances from the extruder, its frictional engagement with the periphery of the freely rotating roller 13 causes the latter to rotate, simultaneously advancing the monofilament 1'2 of a selected color and pressing the same into periphery of the wire coating. As the material in the monofilament 12 is similar to that of the plastic wire covering .and as the latter is still hot, the material in the m'onolament softens and forms an effective heat sealed bond to the plastic wire covering.

Returning n-ow to FIG. l, after the monofilament 12 is applied to the coating of wire 7, the striped wire ad' vances through a conventional cooling trough 23 and after beingv cooled passes to a capstan and take-up for storage.

As before indicated, the identifying monofilament stripe may be completely embedded in the plastic coating of the wire, or it may be permitted to protrude above the surface of the insulation in the form of a raised ridge. In' FIG. 4, We have shown the monofilament 12 completely embedded and lying flush with the surface of the :insulating coating 7a, while in FIG. 5, the mono-filament 12 is only partly embedded in the insulation 7a, so as to form a raised ridge on the surface of the coated wire.

The extent to which the monofilament 12 is embedded in the coating 7a is determined by the pressure applied by the roller 13 which, as before indicated, is adjustable iby means of the knob 19 'and its threaded stem 17. Also, the depth of the supplemental groove 22 in the roller 13 will have a certain effect upon the depth of embedding the monofilament in the insulating coating. In fact, in some instances it may be desirable to eliminate this supplemental groove where it is desired to completely embed the mono-filament.`

The preformed monofilament 12 may be an extruded filament `of the desired material or it may consist of an elongated strip slit lfrom a sheet of plastic material. In either event, the filament is fed in preformed condition in the manner above described.

In this connection, it might be noted that while the convention-al extruded stripe method possesses certain of the advantages of the monofilament stripe of the present invention, it would be extremely difiicult to produce a raised ridge effect which is made possible in the present instance by the application of the preformed monofil-ament and the pressure control of its application to the hot wire coating.

From the foregoing, it is believed that the invention may be readily understood by those 4skilled in the art without further description, it being borne in mind that numerous changes may be made in the details disclosed without departing from the spirit of the invention as set forth in the following claims.

We claim:
