To secure greater penetration of the binder, a. wetting agent, such as sulfonated oils, saponin, sodium sulfanilate, may be mixed with the rubber dispersion. Where a vulcanized product is desired, the binder may have a suitable vulcani'zing agent added to it and also a suitable accelerator if vulcanizing at low temperatures is desired.

The body thus formed is next subjected on the uncoated side and on the side from which the needles entered to the action of a suitable napping machine which acts to raise'a heavy or thick nap or pile formed by upwardly projecting portions ll of some of the fibres, as shown in Fig. 5, which is preferably trimmed to a substantially uniform thickness or height, as shown in Fig. 6, and imparts to the punched product the appearance'and feel of woven carpet. The interlocking ,of the fibres provides a good foundation for anchoring the napped fibres, and these napped fibres for the most part extend substantially normal to the top of the fabric body. The feltable fibres are preferably animal hair, but other fibres such as hemp, jute, or other vegetable fibres might be used or mixed with the animal hair if desired.

The material thus prepared is preferably then subjected to a suitable stretching operation more severe than it will in most cases ever get in service and to this pre-stretched material a base layer It of suitable material is secured by suitable adhesive, as for example rubber cement. This base layer It may be a pre-shrunk and stretched burlap either with or without a sizing. The finished product is shown in Fig. 6.

I desire it to be understood that this invention is not to be limited to any particular form or series of steps except in so far as such limitations are included in the claims.

What I claim as my invention is:

l. The stepsJn the method of making carpets or rugs of feltable fibres which comprises needling a fibrous bat to a woven fabric base, needling this previously needled material directly to another woven fabric base with the base fabrics adjacent each other and projected fibres from both needling operations between them, applying a sizing and binder to the needled material from the base fabric side and to a depth not materially greater than the first base fabric, and napping the top surface of the needled fibres.

2. The method of making carpets or rugs of feltable fibres which comprises needling a fibrous bat to a woven fabric base, needling this pre-. viously needled material directly to another woven fabric base with the base fabrics adjacent each other and projected fibres from both needling operations between them, applying a sizing and binder to the needled material from the base fabric side and to a depth not materially greater than the first base fabric, napping the top surface of the needled fibres, and adhesively securing a shape-maintaining base layer to the bindertreated side of said needled and napped material.

3. Themethod of making carpets or rugs of feltable fibres which comprises needling a fibrous bat to a woven fabric base, needling this previously needled material to another fabric base with the base fabrics adjacent each other and projected fibres from both needling operations between them, applying a sizing and binder to the needled material from the base fabric side and to a depth not materially greater than the first base fabric, napping the top surface of the needled fibres, stretching the needled and napped material, and adheslvely securing a base layer of pre-stretched material to the binder-treated side of said needled and napped material.

4. A pile fabric which comprises a plurality of superimposed woven base fabric layers needled directly together, a bat of fibrous material needled to said base layers with needled fibers from said fibrous material enmeshed between said layers, a binder coating on the base side of said fabric penetrating to the upper of the fabric layers, the fibers between said base layers acting to check penetration of said coating beyond said fabric layers, the uncoated. side having a relatively large proportion of surface fibers projecting therefrom to form a thick pile or nap.

5. A pile fabric which comprises a plurality of superimposed woven base fabric layers needled directly together, a bat of fibrous material needled to said base layers with the needled fibers from said fibrous material enmeshed between said layers, a binder coating on said fabric layers penetrating to the upper of the fabric layers, the fibers between said base layers acting to check penetration'of said coating beyond said fabric layers, the uncoated side having a relatively large proportion of surface fibers projecting therefrom to form a thick pile or nap, and a base layer secured to the coated side of said superimposed base fabric layers.

Q, A pile fabric which comprises a plurality of superimposed woven base fabric layers needled directly together, a bat of fibrous material needled to said base layers with the needled fibers from said fibrous material enmeshed between said layers, a binder coating on said fabric layers penetrating to the upper of the fabric layers, the fibers between said base layers acting to check penetration of said coating beyond said fabric layers, the uncoated side having a relatively large proportion of surface fibers projecting therefrom to form a thick pile or nap, and a woven base layer secured to the coated side 'of said superimposed base fabric layers.
