Abstract

A shear band for a tire includes an annular first, radially outer fabric layer extending circumferentially around the tire; and an annular second, radially inner fabric layer extending circumferentially around the tire. The shear band is formed from a single shear band strip helically wound circumferentially and axially with a first edge of the shear band strip. The first edge of the shear band strip has a first extension flap for engaging an opposite second edge of the shear band strip. The first extension flap is continuously secured to the opposite second edge linearly along the opposite second edge of the shear band strip.

First claim

What is claimed:

1. A shear band for a tire comprising:
an annular first, radially outer fabric layer extending circumferentially around the tire; and
an annular second, radially inner fabric layer extending circumferentially around the tire, the shear band being formed from a single shear band strip helically wound circumferentially and axially with a first edge of the shear band strip, the first edge of the shear band strip having a first extension flap for engaging an opposite second edge of the shear band strip, the first extension flap being continuously secured to the opposite second edge linearly along the second opposite edge of the shear band strip.

2. The shear band as set forth in claim 1 wherein a first planar side of the single shear band strip comprises the first, radially outer fabric layer and a second planar side of the single shear band strip comprises the second, radially inner fabric layer.

3. The shear band as set forth in claim 2 wherein a blade cuts the helically wound shear band strip such that the single helically wound shear band strip has annular parallel opposite edges define the first planar side and the second planar side.

4. The shear band as set forth in claim 1 wherein the first extension flap is secured to the opposite second edge by stitch-knitting.

5. The shear band as set forth in claim 1 wherein part of the first radially outer fabric layer of the shear band includes the first extension flap.

6. The shear band as set forth in claim 1 wherein the second edge of the shear band strip has a second extension flap for engaging the opposite first edge of the shear band strip.

7. The shear band as set forth in claim 6 wherein the second edge of the shear band strip has a second extension flap for engaging the opposite first edge of the shear band strip, the second extension flap being continuously secured to the opposite first edge linearly along the second opposite edge of the shear band strip.

8. The shear band as set forth in claim 6 wherein the second extension flap is continuously secured to the opposite first edge linearly along the first opposite edge of the shear band strip.

9. The shear band as set forth in claim 6 wherein the second extension flap is secured to the opposite first edge by stitch-knitting.

10. The shear band as set forth in claim 6 wherein part of the second radially outer fabric layer of the shear band includes the second extension flap.
