Abstract

An improved tubular openwork fabric or net for food products, the openwork fabric including alternating cojoined and intermediate members, each intermediate member including a filament assembly and each cojoined member including a pair of filament assemblies that are worked together, the filament assemblies being extensible and the open work fabric being extensible in both longitudinal and transverse directions.

Claims

1. A tubular net formed of an openwork fabric comprising alternating cojoined and intermediate members, each intermediate member comprising a filament assembly and each cojoined member comprising a pair of filament assemblies that are worked together, each filament assemblies being extensible and comprises of one or more filaments that comprise elastic thread such that the open work fabric is elastically extensible in both longitudinal and transverse directions such that when stuffed with a food product the alternating cojoined and intermediate members stretch to provide indentations on the food product to define a surface pattern wherein the shape and size varies with a diameter of the food product retained within the tubular net

wherein each cojoined member comprises a pair of adjacent filament assemblies that transition from adjacent first and second intermediate members by joining to form a first end of a cojoined member and separate at a second end of the cojoined member to form adjacent third and fourth intermediate members, and each intermediate member comprises a chain stitch to form a filament assembly, and each cojoined member comprises a chain stitch of a pair of filament assemblies.

2. The tubular net formed of an openwork fabric of claim 1, wherein each filament assembly transitions from an intermediate member in a first direction into a cojoined member and then transitions into a subsequent intermediate member in a second direction to form a hexagonal pattern, such that each filament assembly extends substantially longitudinally along the openwork fabric as the filament transitions through alternating cojoined and intermediate members.

3. The tubular net formed of an openwork fabric of claim 1, wherein each cojoined member comprises two chain stitches of filament assemblies that are joined together.

4. The tubular net formed of an openwork fabric of claim 1, wherein the filament assemblies are formed from one or more filaments that comprise one or more non-composite elastic threads.

5. The tubular net formed of an openwork fabric of claim 1, wherein each filament assembly comprises a composite filament.

6. The tubular net formed of an openwork fabric of claim 5, wherein each composite filament comprises an inner layer and an outer layer, the inner layer being extensible and the outer layer comprising at least one spiral winding of an inextensible thread.

7. The tubular net formed of an openwork fabric of claim 6, wherein the inner extensible layer comprises natural rubber, synthetic rubber or elastane.

8. The tubular net formed of an openwork fabric of claim 5, wherein each composite filament comprises an inner layer and an outer layer, the inner layer being extensible and the outer layer comprising two or more threads braided together.

9. The tubular net formed of an openwork fabric of claim 8, wherein the inner extensible layer comprises natural rubber, synthetic rubber or elastane.

10. The tubular net formed of an openwork fabric of claim 1 wherein, in use, the openwork fabric provides indentations on the surface of a food product along a full length of the food product in which the diameter varies with length.

11. A meat food product covered with the tubular net of claim 1.

12. The meat food product of claim 11 wherein the meat product is a rugby ball shaped meat product with a hexagonal surface pattern wherein a size of a hexagon increases with the diameter of the meat product.
