Abstract
Abstract of the Disclosure A cushioned panel is provided together with a method of molding it. A non-woven fabric having an outer layer composed of polypropylene or other thermoplastic fibers is heated to the melting point of the fibers. It is inserted into a mold having a decorative surface fabric and a piece of foam cushioning therein. The mold is designed so that the edges of the male and female mold halves compress the molten non-woven substrate and the surface fabric forcing the molten surface of the substrate into the interstices of the surface fabric. A mechanical bond is formed upon cooling.

2. Brief Description of the Prior Art.
The bonding of textiles to various substrates such as textiles, paper, plastics and metals has been accom-plished through dielectric bonding, spray or heat activated ¦ adhesives, sewing, and heating and pressing.
In U.SO Patent No. 3,562,052, an interior lining for motor vehicles is made by sprinkling a needle fleece with polye-thylene powder and heating the powder to its melting point. Upon cooling, the flee^e fibers will be anchored in the polyethylene layer. The resulting lining may be heated and placed in a die to shape it in a desired form.
U.S. Patent No. 3,713,936 discloses a laminate including a fabric layer secured to a non-woven mat by means of an adhesive material, the mat being secured to a thermoplastic material by a heat fusing step. The laminate is then placed in a mold of an appropriate shape.
U.S. Patent No. 4,186,235 discloses a method wherein a non-woven cloth is positioned against the article-l defining surface of a mold and a thermoplastic material is ¦ then introduced. The material may be a foam. Heat and ¦ pressure are applied to fuse the cloth and material.

¦ U.S. Patent No. 4,199,635 discloses a method ¦¦ of producing a decorative laminate pànel such as used in the ¦~ interior of automobiles. An unconsolidated layer of synthetic 1ll fibers and a layer of melt fibers are applied to a con-! tinuously advancing web of melt fibers. The three layers are then needled to form a composite web. A batt is needled to the composite web and a decorative fabric is applied to the layer of melt fibers. Heat and pressure are then applied.
Summary of the Invention The invention is directed to a method of bonding two textile materials to each other as they are being molded.
The product obtained in accordance with the method may be used as a trim panel inserted in a door of an automobile.
Il Other applications would also be possible. A unique mold l¦ configuration is also employed which allows two materials to ~¦ be bonded in selected areas and permits the incorporation of a cushioning material between the two materials.
In accordance with the method, a first fabric l including at least an outer layer of thermoplastic fibers is heated to a point in excess of i-ts melting point. The first fabric is inserted within a mold having a second fabric -therein.
A piece o foam of appropriate size and shape is positioned between the two fabrics. The mold is designed so that the ~l edges of the male and female halves thereof compress the juxta-ll posed portions of the fabrics causing the molten surface of the first fabric to penetrate within the interstices of the 1 ' I

ll9~
second fabric. Upon cooling within the mold, a mechanical ~¦ bond is ~ormed between portions of the two fabrics. The ¦I resulting structure is a panel having cushioning material l locked between two fabrics. No cushioning material is visible 1 from either side of the panel.
The method according to the invention is ad-vantageous in that no powders, films, or adhesives need to be used. No secondary operatlon is required to attach a fabric to a molded substrate. The bonding of the two fabrics will withstand relatively high temperatures for long periods of time.

Detailed Description of the Invention _ _ A eirst non-woven fabric 10 similar in construction to the material described in U.S. Patent No. 4,199,635 is pro-vided. The fabric 10 has outer layers composed of polypropy-lene or other thermoplastic fibers. Unlike the patented structure, an outer decorative surface is not yet provided.
A layer of batting has also been omitted from the structure I shown herein.

A decorative knit, woven or non-woven surface ¦ .
fabric 12 is also provided. The surface fabric 12 has a ..
textile backing. A die cut piece of foam 14 is laid over ¦I the surface fabric 12 when the latter is positioned over ~ the female portion 16 of a mold 18. The textil.e backing of ¦I the surface ~abric contacts the foam. The first non-woven l fabric 10 is then placed over the opposite side of the foam ; 14 sandwiching it between the two fabrics. As shown in the drawing, the foam is laid over the surface fabric in such a manner that the outer perimeter of the cavity 20 of the fe- .
male portion 16 of the mold is not covered thereby. Decora-tive blades may be incorporated in the surface defining the cavity.
l~ The mold 18 is designed so that the edges of the L
lll male 22 and female 16 mold halves compress the non-woven I Ij substrate and the surface fabric into an area approximately 0.040 inches thick. Prior to the compression, the first non-woven fabric 10 is heated to a point beyond the melting point ¦
~¦ of its outer layers. If the outer layers are composed of ~ polypropylene fibers, heat should be applied until the tempera-ture of the fibers exceeds 390F.
: The molten non woven fabric 10 and the surface fabric 12 are compressed within the mold as shown in Figure 1 A symmetrical space is provided between the surface of the cavity 20 and the projecting portion 24 of the male half of : the mold 18 to accomodate the foam 14. High pressure is not~ applied to the foam during the molding operation. The pres9ure ,~
! . , I
119~8'~6 exerted by the mold halves forces the molten surface of fabric 10 into the interstices of the surface fabric 12. Upon cooling, a mechanical bond is formed between the two fabrics, particularly in the tapered areas 26 which may be referred to ¦ as the "pinching gaps" where pressure is relatively high.
The molded part is then die cut or cut by other mechanical means from the full sheet (not shown) and is ready for use.
A structure as shown in Figures 2-3 may be obtained. Other configurations would of course be possible.
The illustrated structure includes substantially flat opposing surfaces 28, 30 and a pair of projecting portions 32, 34 extending from the bottom surface. Due to the shape of the mold, the thickness of the molten non-woven fabric 10 ~ ~ is significantly compressed in the area of the projecting ;` 15 ~ portions 32, 3~ providing excellent bonding between it and the decorative surface fabric 12. The foam does not extend between the fabrics in the bonding araa and only a portion of it is compressed in the pinching gap 26. This compression sub-stantially locks the foam in place between the two fabrics 10, 12. The decorative surface fabric 12 defines three contiguous surfaces o the panel. The fourth surface 30 is defined by the first fabric 10.

A method as described in claim 2 wherein a relatively small portion of said foam piece extends within said tapered area, said small portion of said foam being partially compressed during the applying of pressure by means of said mold thereby locking said foam piece securely in place between said first and second fabrics.
4. A method as described in claim 3 wherein said space is symmetrical and includes a pair of opposing tapered areas, relatively small opposing portions of said foam piece extending into each of said tapered areas and being partially compressed during the applying of pressure by means of said mold thereby locking said foam piece securely in place between said first and second fabrics.
5. A method as described in claims 1, 2 or 3 wherein said first fabric is a non-woven fabric and said second fabric includes a decorative surface.
6. A method as described in claims 2 or 3 wherein a portion of said first fabric is compressed within said tapered area, the bonding of said first and second fabrics occuring at portions where said first fabric is com-pressed.
7. A decorative laminate panel comprising:
a first fabric having at least one thermo-plastic surface;
a second fabric having an edge portion bonded to an edge portion of said thermoplastic surface of said first fabric, said thermoplastic surface of said first fabric at least partially penetrating within said second fabric creating a mechanical bond therewith, said second fabric in-cluding an outer decorative surface, and a piece of foam positioned between and con-tacting said first and second fabrics.
a first fabric having at least one thermo-plastic surface;
a second fabric having an edge portion bonded to an edge portion of said thermoplastic surface of said first fabric, said thermoplastic surface of said first fabric at least partially penetrating within said second fabric creating a mechanical bond therewith, said second fabric in-cluding an outer decorative surface, and a piece of foam positioned between and con-tacting said first and second fabrics.
8. A panel as described in claim 7 wherein said decorative surface defines first, second and third sides of said panel, and a surface of said second fabric defines a fourth side of said panel opposing said first side, said second and third sides adjoining said first and fourth sides, respec-tively.
9. A panel as described in claim 7 having in cross section a body portion and two symmetrical projecting portions forming a generally U-shaped configuration, said foam piece being positioned between said fabrics for the length of said body portion, said fabrics being bonded to each other near the outermost portions of said projecting portions, said first fabric having a progressively decreasing thickness in the direction of the outermost portions of said projecting portions, said foam piece having opposing edge portions ex-tending partially within said projecting portions between said fabrics, said edge portions being compressed.
