## Abstract

The present invention relates to a production method of tire cap ply strip (100) by using MICRO SPIN method. The objective of the invention is to provide a production method of tire cap ply strip (6) which is obtained in non-woven state and by the method of micro spinning in order to eliminate the additional processes such as calendaring, coating by extrusion.

## Claims

### Claim at position 1

1-5. (canceled)

### Claim 6

A method of producing of a tire cap ply strip the method comprising:
dipping a plurality of single cords therefore creating a plurality of dipped single cords;
feeding the plurality of dipped single cords to a system;
passing the plurality of dipped single cords through a reed;
conveying the plurality of dipped single cords which are separated by the reed under a spinnerets by the help of a plurality of rollers;
discharging molten polymer which has become yarn/string via spinnerets to the cords; and
obtaining the tire cap ply strip.

### Claim 7 (depends on 1)

The method of claim 1 wherein the step of dipping further comprises:
applying a polymer mixture on spinnerets wherein the polymer is selected from a group consisting of polyamide (nylon), polyesters, acrylic materials and meltible styrene butadiene polymers or a mixture of these used as filament.

### Claim 8 (depends on 1)

The method of claim 1 wherein the polymers discharged on the plurality of single cords are molten at a temperature range of 50-300° C. after dipping of the plurality of single cords.

### Claim 9 (depends on 2)

The method of claim 2 wherein the polymers discharged on the plurality of single cords are molten at a temperature range of 50-300° C. after dipping of the plurality of single cords.

### Claim 10 (depends on 2)

The method of claim 2 wherein the polymers discharged on the plurality of single cords being an adhesive material in order to keep the single cords together after dipping the plurality of single cords.

### Claim 11 (depends on 3)

The method of claim 3 wherein the polymers discharged on the plurality of single cords an adhesive material in order to keep the single cords together after dipping the plurality of single cords.

### Claim 12 (depends on 4)

The method of claim 4 wherein the polymers discharged on the plurality of single cords being adhesive material in order to keep the single cords together after dipping the plurality of single cords.
