Another ob ect of this invention is to provide a' process of the character described which is-sim- -ple and adapted to be carried out by even unskilled persons.

More particularly, it is an object of this invention to provide a process for the application of continuous strands of fibrous material to a resilient or rubber-like base. which process includes the step of reciprocating a hollow needle into and out of sa d base. the needle having threaded therethrough the strands of fibrous ma- 1 terials whereby a plurality of loops of fibrous material areapplied to the base, which loops may then be cut, and the resulting strands curled or waved to simulate natural hair.

Other obiects and advantages of this invention it is believed may be readily apparent from the following detailed description of a preferred embod ment thereof, when read in connection with the drawings.

Figure 11 is a fragmentary side elevation, partly in section, illustrating the fibrous strands anchored in place by means of the method illustrated in Figure 10.

Referring now to the drawings, the preferred embodiment of this invention is illustrated in view illustrating connection with the production of a dolls head generally indicated In. The dolls head is preferably formed of a resilient, rubber-like material, and preferably is molded, in a manner familiar to those skilled in the art, of a plasticized resin composition. It is preferred to use a relatively soft, plasticized vinyl chloride polymer, although anv material having resilient or rubber-like properties may be'used.

Secured to the base or scalp portion H of the head In is a plurality of hair-simulating strands of fibres l2. These fibres are a plied to the head in accordance with the process illustrated in Figures 4 through 6. In carrying out this process a hollow needle I3 is provided. and it has been found that needles such as hypodermic needles are ex ellently suited to be used in carrying out this rocess. It is preferred to use a hypodermic needle having a so-cal ed Huber point, which as shown. comprises a ho low needle having a curved and shar ened end I5. I It has been found that there is less ten ency for a needle of this type to cut out portions of the base material, but

success ully ued and. in fact, any relatively narrow hollow needle having a sharp point and an openin ad acent the po nt may be used.

The needle 13 is threaded with a number of stran s of continuous fibre [6. A preferred type of material is a denier extruded fibre sold under the trade name Saran, a vinylidine chloride plastic material. Here again other materials may be used, such as, for example, Vinyon, nylon, or any other suitable continuous fibre material. Synthetic fibres of this type are preferred, since they closely resemble human hair when applied by the process herein described. As shown, it is preferred to thread four strands of the continuous fibre through the hollow needle 13, the free ends 20 of the strands extending through the lower opening 2| of the needle and the other ends of the strands extending to a supply spool or spools (not shown).

The needle is thus loaded is then caused to be moved in a path to reciprocate into and out of the scalp portion ll, from the position shown in Figure 4 through the respective positions illus trated in Figures 5 and 6. The needle during its downward stroke is caused to completely penetrate the base scalp portion so that the strands are caused to form the lower loops 23 shown in Figure 6. As the needle is withdrawn, the loops remain in place, due to the'fact that-the free legs z lthereof are gripped'by therubberdike material of the scalp portion, and there being little frictional resistance between the supply legs of the loops and the needles'ince' the supply legs are completely encased within the needle.

There is therefore no tendency for'tl'ieloo'ptobe pulled out as the needle withdrawnor re=- tracted. The needle is caused alternately to penetrate and be withdrawn over the entire area of the scalp portion, the points of penetration being spaced sufficiently close together to -afford complete coverage. Upper loops 36 are thereby formedand these loops are out sit-their outer ends, and the resulting single-"strandsarecurled or wavedto pi-oduce the fln'ished hair coveringillustr'ated'in Figures 1 and 2'. I

The inherent resiliency ofythe base material 'tendsto maintain th'e'strandso'f hair in place,

but" 111- career to avoidpulli'ngout ofthe hair on rough handling the fibres arefirliilyanchored in place; A" preferred method for anchoring the soles shares the use of an adhesive material. no adhesiv'mat'erial may be uses-'wnidhis not compatible'with' the material of di eases-recap portion, 1; el, one which does not have-a solvent action for the base" material, or" vice versa'. I prefer to "e' ordinary carpenters glue; but other adhesives'such as calcined magnesium oXyc'l iloride in a solution or magnesium chloride (is-22 Bi), plaster of Paris; etc; may 'be'used. The'liquid adhesive is merely poured into the inverted head and allowed to set as afllm indicatedat33, whereby the strands arefirnilyanchored in place.

While the reciprocation" of the needle may be accomplished by ha d, it" is preferred to mount a gang'o'f at least four needlesupoh a machine (not shown) is arranged to vertically reciprocate the gang of needles. such machine is neither shown nor described in detail since any mechanical device maybe" used and since it does not per se form a part oftliis'invefition. r further'facilitate' the operation the head i il'is'placed upon a mandrel 39 which is mounted directly snow the-needle is m-jbeids the eerie" of needles, as the case may be, the assessments provided was a central recess a! in which the needle or needles are received at the lower portion of the downward stroke. When the needles are mounted for mechanical reciprocation as described above the operator simply moves the head about on the mandrel to obtain complete coverage of the scal portion.

In Figure 7 is illustrated a modified method for securing the hair to the scalp portion H. Here a jet of gas is forced through a nozzle ii], the gas being at a temperature sufiiciently high to cause the loops 23 to become fused. It has been found that with fibres of thermoplastic material such as Saran, hot air at a temperature of about 660 F. is satisfactory in fusing; the loops without affecting the scalp portion H; It has been found that the jet of hot air need only be directed atany onegroup of loops for only a few seconds to fuse the loops into the form of nodules indicated at 42 in Figure 8; These lumps or nodules 42 are of sufiicient size so that they prevent withdrawal of the air strands from the scalp portion. During the process of fusing, the loops tend to curl and shrink so that the nodules 42 thus formed are brought into contact with the underside of the scalp portion i! as shown in Figure 8.

Another modified method for anchoring the hair strands in place on the scalp portion is shown iii-Figure 9. Hre a relativelythin film $5 of thermoplastic material of the same type as that used for the hair strands is placed inside of the scalp portion H and against the loops 23. A'heate'd'ma'ndrel or die 46 is then inserted into the scalp portion and contacts the film 45 under pressure'to fuse the same integrally with the loops 23.

In-Figure it) is illustrated a further modificatlon of the invention. In carrying out this form of the invention, the hair strands are spaced relative to-thelength of the=loops23-so that-when the loops are deformed to the -position shown. in

Figure ll, adjacent loops are: iii-contactwith each other.- Inorder to anchor the'stlands in place=a heated die ifi isdrawnacross the underside of the scalpportion it with sufficient pressure to'force the loops 23 against the scalp portion-and. to-fuse-adjacentloopstogether as shown in Figure 11.

While the proccsswhich embodies this invention has been described with reference to the application of hair-simulatingfibzes to'- adoil s head, it will be readily apparent thatt-he process isnot inherently so limited, and may be used in applying hair to toy animals and the like, and in the manufacture of other products adapted to simulate hair, such as wigs and the like. Furthcrmore,while-the base H isdescribBd' as being of a rubber-like material, itisapparent that'a fabric base impregnated with a rubber-like material may oe'used.
