NON-SLIP BONING MATERIAL Filed Aug.
INVENTOR. FeAHvkm/v D/p/v 2,773,265 NON-SLIP BONING MATERIAL Franklin Dick, New York, N. Y., assignor to Richard A. Fisch, Long Island City, N. Y.
Application August s, 1953, Serial No. 372,561 2 Claims. c1. 2-2s6 This invention relates to a non-slip plastic boning material, to the process of making same and to the combination of the non-slip boning material with a jacketing.
Artificial plastic boning is used extensively in the garment industry, both for undergarments and outergar ments, in order to provide desired stiffness along certain lines. Artificial plastic boning as it has been made heretofore is formed with a smooth and slippery surface. In garments the boning material is confined in a jacket or channel of tape to obtain the stiffness along the desired lines. With the smooth surfaced plastic boning of the prior art substantially all the thrust or compressive strain on the garment containing boning material must be borne by one or both ends of the jacket, usually the bottom end. Continuous slipping and rubbing will cause the ends of the boning to pierce the fabric and may also cause the ends of the boning to shred. Also, in garments such as dresses the problem of sWivelling occurs, wherein the boning twists or swivels and must be straightened out with care before the dress can be worn.
One phase of this invention is based on the discovery that it is possible to distribute the strain or thrust of the boning all along the sides of the fabric confining channel so that a substantial portion of the wear and strain at the ends of the channel is eliminated.
Among the objects of the invention, therefore, is to provide a boning material which will frictionally grip the fibers in a fabric confining channel to prevent slipping of the bone in the said channel.
Among other objects of the invention is to provide a boning and tape combination adapted to be attached to garments which combination is capable of supporting the garments along the desired line without all the thrust and strain being concentrated at the end of the confining tape and without any tendency toward swivelling.
These objects and others ancillary thereto are obtained by providing a thermoplastic strip with a roughened surface adapted to frictionally resist movement along a fabric such as a binding tape. The roughened surfaces may take the form of transverse ridges or depressions, of two or more series of diagonally-crossed, indented lines of diamond shaped indentations or ridges, longitudinal ridges formed during extrusion which are broken or afterwards interrupted, for example, or any other similar design. Preferably the indentions, are of a depth and spacing which is large enough to catch or grip the threads of the jacket or confining fabric with which the boning is to be employed but of insufficient size to change the smoothness of the jacket itself when the boning is in place therein. A very satisfactory surface is one which duplicates the projections on grade sandpaper.
The invention will be best understood from the following description of exemplifications of the same when read in connection with the accompanying drawing in which,
Fig. 1 is a top view of a boning material made according to the invention.
Fig. 1A is an end view of the boning of Fig. 1.
United States Patent P 2,773,265 Patented Dec. 11, 1 9356 Fig. 2 is a view illustrating one method of forming the boning of the invention.
Fig. 3 is a top view partly cut away, of the boning and jacket or confining tape combination.
Fig. 4 is a cross sectional view taken along line 4-4 of Fig. 3.
Fig. 5 is a view of a brassiere containing the jacketed boning of the invention.
The form of boning shown in Figs. 11 and 1A consists of 'astrip 10 of plastic material having a plurality of criss-crosse'd indentations 11, 12 on the flat sides thereof. The indentations compose, for example 60 parallel lines to the inch in each direction. The boning can be made from the thermoplastic material by extruding, rolling, laminating, or otherwise molding the same. The thermoplastic material employed may be any of the known thermoplastic materials which have desirable strength, flexibility, etc. A preferred material is the incompatible mixture of cellulose acetate and cellulose acetate butyrate which is molded by extruding into strip form whereby a unitary product with an embedded thread structure is formed as disclosed in U. S. Patent No. 2,531,234.
One method of making the boning 10 is shown in Fig. 2. The smooth surfaced strip 10 is extruded from nozzle 13 and while still soft is passed between the embossing surfaces of rollers 20, 21. Preferably the rollers 20, 21 are heated to the softening point of the thermoplastic material of strip 10 but if sufliciently close to nozzle 13 they do not need to be heated. The rollers 20, 21 when heated to the softening point of the thermoplastic material may be employed to roughen the surface of said strip 10 at any time after extrusion. Brushes 22, 23 may be provided to remove adhering particles of thermoplastic material from rollers 20, 21, respectively.
The boning of Figs. 1-2 can be jacketed or encased in a confining fabric 30 as shown in Figs. 3 and 4. Preferably two fabric tapes 31, 32 with folded edges 33, 34 and 35, 36 are sewed together at 40, 41 to surround the boning 10. The stitches are formed simultaneously on a double needle sewing machine and there is a limit to the tightness of fit obtainable so that the jacket or encasing tape does not fit very snugly about the boning. For this reason the jacketed boning made heretofore would slip very easily within the confining fabric. However, with the boning of the present invention there is a definite interlocking obtained between the projecting portions of surfaces 11, 12 and the interstices of the covering channel 30.
Fig. 5 shows a brassiere cup 50 containing two jacketed boning members 30-1 and 30-2. The boning members 30-1 and 30-2 may be attached at two or more regions by sewing the tape members 31, 32 to the body of the brassiere. The number of attaching points depends on the flexibility desired in the garment, etc. The ends of the tape 31, 32 must, however, be secured to the garment. Usually the tape and bone combination is cut to a size somewhat longer than desired, the ends of the internal boning 10 are cut off to provide an overlapping fabric at the end and the overlapping ends are: folded back on themselves before attaching to the garment. Regardless of how the ends are attached, all the compressing forces to which the garment is subjected would be transmitted in full to one end of the confining tapes 30-1 and 30-2 if this boning is smooth surfaced. With the boning of the invention a considerable portion of such a compressive force is distributed along the tape 30-1 or 30-2. There is less tendency for the boning tape to fail at the ends. In addition to aiding in distributing the forces applied to the garment to which the boning is applied a much more stable and desirable stiffness is obtained due to the tendency of the boning 10 to stay in position.
The features and principles underlying the invention described above in connection with specific exemplifications will suggest to those skilled in the art many other modifications thereof. It is accordingly desired that the appended claims shall not be limited to any specific feature or details shown or'described in connection with exemplifications thereof.
I claim:
1. In combination a synthetic boning material comprising a longitudinal strip comprising two incompatible thermoplastic materials, said strip containing a multiplicity of toughening projections extending upwardly from substantially the entire fiat surface regions thereof and a tape-like fabric jacketing the said strip, the depth and spacing of the said projections being of a size sufiicient to catch the surface of the threads of said jacketing fabric but of insufiicient size to :change the smoothness of the jacket itself when the boning is held therein.
2. In combination a synthetic boning material comprising a longitudinal strip comprising the incompatible mixture of cellulose acetate and cellulose acetate butyrate, said strip containing a multiplicity of roughening projections extending upwardly from substantially the entire flat surface regions thereof and a tape-like fabric jacketing the said strip, said jacketing comprising a projecting portion extending along each side edge of said internal boning, the depth and spacing of the said projections being of a size sufficient to catch the surface of the threads of said jacketing fabric but of insuffi-cient size to change the smoothness of the jacket itself when the boning is held therein, said strip and jacket therefor being relatively long with respect to the length of boning required in a garment whereby appropriate lengths may be cut therefrom and secured to a garment.
