Beschreibung
Zusammenfassung:	A shear band (10) is disclosed comprising an annular first, radially outer fabric layer (21) and an annular second, radially inner fabric layer (22). The shear band (10) 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 having a first extension flap (310) for engaging an opposite second edge of the shear band strip. The first extension flap (310) is continuously secured to the opposite second edge linearly along the second opposite edge of the shear band strip. Further, a tire comprising such a shear band (10) is disclosed. Finally, a method for constructing a plurality of shear bands (10) is disclosed, the method including the steps of: helically winding a single shear band strip about itself to produce a cylindrical structure; securing a first edge of the single shear band strip to a second opposite edge of the single shear band strip by a first extension flap (310) extending from the first edge of the single shear band strip; and axially and circumferentially cutting the cylindrical structure in multiple locations.
