Claims. (Cl. 154-77) This is a continuation-in-part of my copending application Serial Number 277,950 filed on March 22, 1952, now abandoned.

This invention relates to a method or process of making semi-artificial fur seamless material or patterned pieces from a natural fur pelt or a number of pelts by using the hair from the pelts, retaining the natural organization and arrangement of animal hair in the finished product.

Those skilled in this art readily appreciate the limitations in the use of fur for garments, trim material and the like. Among many others are the impossibility of washing it, the expense in some instances, incorrect density of hair, and others. It is the object of this invention to teach a method of making semi-artificial fur, that is natural fur but unnatural backing for the hair is used, which can be washed without injury thereto, which is more inexpensive than natural fur but is in appearance much like a natural fur since the same organization of real fur or hair is maintained.

Often a low grade of pelt must be discarded or used in such capacity as to be almost valueless. In those instances where the cause of the low classification is the sparseness of hair, the present method provides a correction making it possible to salvage much material. Accordingly, it is an object of this invention to provide the teaching or" a step which increases the density of hair that will be used in the finished product. Conversely, if desired, a very dense pelt may be stretched over a larger area by decreasing the density of hair prior to application of a backing upon it. The above mentioned step with its alternatives make it possible to regulate the quality factor of the finished product depending upon the volition of the person practicing the invention.

A more specific object of the invention is to apply a coagulant to the hair side of a fur pelt, the coagulant being flexible and pliable, remove the leather skin from the pelt, thereafter slide the remaining coagulated hair down a slippery surface, the inclination of which is adjustable to cause the coagulated hair to crowd together or stretch, turn the coagulated hair over so that the roots of the hair are exposed upwardly and at the same time again control the crowding and stretching of the coagulated hair, applying a pre-cut sheet of backing having an adhesive face on the root ends of the coagulated hair, and finally apply heat and/or pressure to the backing to complete bonding between the fur hair and the backing. The crowding or stretching of the coagulated hair may be accomplished by actuating conveyors that successively transport the hair at difierent relative speeds.

Another object of the invention is to provide the backing of the previously described article and made by the above method, by spraying a suitable plastic directly upon the coagulated assembly of hair, the plastic material being any one of the large number of those commercially available, which are thermoplastic or normally in the liquid state and air dry to a pliable film attached to the hair.

Another object of the invention is to provide a method, the practice of which avoids the necessity of having to cut the fur piece, which operation is diflicult and which often reduces the value of the cut fur, by pro-cutting the backing sheet to pattern size and shape prior to applying the backing sheet to the fur.

Ancillary objects and features such as being able to produce the finished product in any degree of pliability by selection of backing, and the production of any length and width of products, will become apparent in the following description of the specifically disclosed form of invention.

Although I have illustrated only two apparatus capable of practicing the method to be described in detail, there are a great number of alternative structures which can be used, and the method may be practiced by hand.

A common, ordinary pelt, for example a rabbit, sheep or lamb, or other fur bearing animal pelt, is to be considered, it being obvious that any pelt may be used. After initial preparation for softening and cleaning, a coagulant is manually or mechanically brushed by brush [2, on the hair of the pelt p. The coagulant may be a solution of glucose or any other pliable, flexible and soluble coagulant, several of which are commercially available at this time. The purpose of this coagulant is to hold the fur hair in place while the leather skin s of the pelt is being cut therefrom, and to give added weight which improves the rate of descent down the slide 10. After applying the coagulant, the pelt p is allowed to dry naturally or this step is accelerated by passing the pelt p through a dryer 12 or under a bank of heaters such as infrared lamps or heat coils. After drying, if it is determined that the coagulant is heavier than neces sary for the type of pelt being treated, the skin may be brushed to remove some of the coagulant.

Next, the coagulated pelt is fed between the juxtaposed fluted rollers 14 and 16 which feeds the pelt p to the cutter c that removes the skin s from the pelt, the coagu lated hair being held in place in its natural, original ar rangement and organization by the coagulant. The cutter and the feed rollers are of the type known in the art for removing the skin from the pelt. The skin is shredded in this operation and the residue falls in a chute 18 for reception in a container 20. As the coagulated hair passes around the roller 16, it is guided by the plate 22 upon the slide 10 having a smooth surface, whence it descends at a rate controlled by the angle of inclination of the slide. This angle may be varied by changing the included angle between the slide 10 and a conveyor 26 at the discharge end of the slide. Such an angle change may be arrived at by a variety of means such as mounting the slide on pivot bolts 28 having nuts carried in slots 30 which are formed in links 32 that hold the lower end of the slide '10. If the conveyor roller 34 is also carried by these links, the conveyor 26 may be adjusted to correspond to the adjustment of the slide. Alternatively, the slide angle may be adjusted by the simple expedient of providing vertical screws in it to serve as feet at the lower end thereof.

If the slide is angled steeply, the coagulated fur hair will descend rapidly and compact as it strikes the conveyor 26. But if the slide it) is angled less steeply, the rate of descent will be lower and assuming constant conveyor speed, the coagulated assembly of hair will be stretched due to the pulling effect of the conveyor on the coagulated hair. This is possible because of the presence of pliable and flexible coagulant, and accordingly, the density of the hair may be selectively regulated, while retaining the original arrangement of hair.

During the above operation, the root ends of the hair are down, that is, the coagulated hair is supported by the root ends of the hair. But to inspect the hair, it is necessary to see the root ends of the hair, and the next procedure is to turn the coagulated hair over so that the root ends thereof are exposed upwardly. This is done by locating a conveyor 36 with its upper flight below the conveyor 26, the confronting and adjacent flight of the conveyors Z6 and 36 operating in the same direction. Hence, when the coagulated hair falls from the conveyor 26 upon the conveyor 36, it is reversed with the root ends of the hair facing upward, in lieu of or in addition to the density control step described previously, the relationship of the

conveyors

26 and 36 may be used to control the density of fur hairs. If the speeds of the

conveyors

26 and 36 are identical there will be no compacting or stretching of the hair assembly and therefore the density will be unchanged as the coagulated hair is transferred from one conveyor to another. However, by increasing the speed of the conveyor 36, the density may be decreased because less hair is fed than is capable of being handled. Selectively, by decreasing the speed of conveyor 36 with respect to the other conveyor, the density will be increased due to the compacting of the hair assembly at the inlet part of the conveyor 36.

Now, the coagulated hair is ready to have a backing sheet applied. Arbitrarily a glove backing sheet 40 has been selected for illustration. One sheet 40 is shown being applied to the fur, the sheet 42 already applied to the fur, and sheet 44' being heated and pressed by the heated roller 46 mounted above the roll 43 of the conveyor 36, by placing the backing sheet upon the coagulated hair manually, several backing sheets may be arranged on a single hair assembly in order that there be as little waste as possible. That hair which is not used may be saved and used for other commercial purposes.

The backing sheet may be selected from a large number of available fabrics, such as, nylon, plastics, hides, and others depending upon the quality and character desired in the finished product. is shown in Figure 4. It includes the sheet 52 together with a layer 5'4 of pressure and/ or heat sensitive adhesive of any known type. The adhesive surface of the backing sheet is placed upon the upwardy exposed root ends of the coagulated hair or hair assembly 56 as shown in Figures 1 and 3. If a heat sensitive adhesive is used, the roller 46 will be heated, if a pressure sensitive adhesive is used, the roller 46 will be used only to exact a pressure on the backing.

In Figure 7 the assembly 56 is shown with two backing panels on it. The panel 66 is secured to the fur of the assembly, and on panel 6-6 there is fixed a fabric panel 68. The purpose of this organization is to show that the backing may be a single material or a plurality of materials used in a laminar fashion.

Instead of machine or manually applyingv a backing to the assembly 56, a backing may be sprayed on the hair f the assembly 56. In Figure 5 the apparatus of Figure 1 is partially reproduced with a slight structural modification. There is a tank 60 containing a vinyl plastic or A typical backing sheet 5%) some other type of plastic and it is to be conducted through conduit 62 to discharge nozzle 64. The nozzle is directed toward the upper surface of conveyor 36 on which the assemblies 56 are disposed. Thus, as coagulated hair assemblies are conveyed under nozzle 64, they are sprayed with the plastic material which becomes plastic backing 66. Obviously, the use of valves to control the actual flow and/or rate of flow from nozzle 6 may be resorted to.

After the backing has been applied by hand, machine or spraying, the finished product may be treated for finishing purposes, such as dyeing, cleaning out the coagulant, fiufling and other known operations such as stenciling and plucking.

it is apparent that various changes may be made without departing from the scope of the following claims.

What I claim is:

l. The method of applying fur to a backing comprising the steps of applying a coagulant to the hair of a pelt, removing the skin from the pelt thereby leaving the hair of the pelt in an orderly coagulated assembly, selectively controlling the density of the hair while the hair is in the coagulated state, placing the backing upon the hair of said assembly, and securing the backing upon said assembly of hair.

2. The method of applying fur from a pelt to a backing sheet comprising the steps of flexibly binding together the hair of the pelt near the roots thereof, removing the skin from the pelt thereby leaving the hair of the pelt in its orderly original assembly, selectively controlling the density of the hair while the hair is flexibly bound together, reversing the hair of the assembly so that the root ends are upwardly exposed while the entire assembly of hair is supported on its front surface, and then securing the backing sheet to the upwardly exposed root ends of the hair of the assembly.

3. The method of claim 2 wherein the density of hair in the flexibly bound state is varied prior to the securing of the backing sheet to the root ends of the hair so that the hair density factor of the finished product may be altered.

4. Method of removing hair from a fur pelt and applying it to a backing comprising the steps of applying a coagulant to the hair while it is still held rooted in the skin of the pelt for the purpose of holding the hair substantially in its natural arrangement, removing the skin from the hair and coagulant thereby leaving the hair substantially in its original arrangement with the root ends of the hair supporting its weight, controlling the density of hair by selectively compacting or stretching the coagulated hair assembly, turning the assembly of hair so that the root ends of hair are facing in an upward direction, and then fastening the backing the root ends of the hair.

5. The method of making an artificial pelt from the hair of a natural pelt while preserving the general organization and arrangement of hair placement of the natural pelt comprising the steps of flexibly conjoining the hair of the natural pelt and then cutting the natural skin from the hair at the roots thereof in order to leave the hair of the natural pelt remaining in its natural organization, sliding the conjoined hair down an inclined surface, selectively stretching or compacting the hair of the natural pelt by varying the angle of inclination of said surface to control the density of the hair while the hair is in the flexibly conjoined state, and then applying a backing to the root ends of the hair.
