Patent ID: 7431063

Claim:
A method of producing a belt structure for a vehicle tyre, comprising: forming a radially innermost belt strip comprising a continuous circumferential extension about a geometrical axis of rotation of a preparation drum, the radially innermost belt strip including a plurality of reinforcing cords; and forming at least one radially outer belt strip comprising a continuous circumferential extension about a geometrical axis of rotation of the preparation drum, wherein the plurality of reinforcing cords in the radially innermost belt strip are parallel to each other within the belt strip so that the reinforcing cords do not cross each other within the belt strip, wherein only the radially innermost belt strip is formed so as to have circumferential broken-line edges each with a profile extending along a broken line, wherein the at least one radially outer belt strip is formed so as to have circumferential continuous edges each with a profile extending along a continuous unbroken line, and wherein the at least one radially outer belt strip has a width smaller than a width of said radially innermost belt strip, so that said at least one radially outer belt strip is contained within the broken-line edges of the radially innermost belt strip.
