Method for manufacturing a green tyre, particularly for manufacturing a breaker ply package for the green tyre on a support surface of a conveyor, wherein the conveyor has a conveyance direction, wherein the method comprises the steps of: producing a first breaker ply having a longitudinal axis, a breaker ply length and mutually parallel cords at a pre-set first cord angle to the longitudinal axis, wherein a leading part of a continuous rubber band provided with substantially parallel longitudinal cords is cut into first strips at the first cord angle, wherein a predetermined number of first strips with cords are juxtaposed substantially parallel at a set strip distance with respect to each other and are spliced together for forming the first breaker ply of a pre-set breaker ply length on the support surface of the conveyor, in the conveyance direction downstream of the first breaker ply producing a second breaker ply having a longitudinal axis, a breaker ply length and mutually parallel cords at a pre-set second cord angle to the longitudinal axis, wherein the leading part of the continuous rubber band provided with substantially parallel longitudinal cords is cut into second strips at the second cord angle, wherein a predetermined number of second strips with cords are juxtaposed substantially parallel at a set strip distance with respect to each other and are spliced together for forming the second breaker ply of a pre-set breaker ply length on the support surface of the conveyor, wherein the continuous rubber band is supplied in the direction of the longitudinal cords by a supply device that can be moved between a first position and a second position, wherein the method further comprises the steps of: prior to manufacturing the first breaker ply placing the supply device in the first position in which the supply device is set for supplying the continuous rubber band at a supply direction which with the conveyance direction includes a first angle that equals the first cord angle, and prior to manufacturing the second breaker ply moving the supply device from the first position into the second position in which the supply device is set for supplying the continuous rubber band at a supply direction which with the conveyance direction includes a second angle that equals the second cord angle, wherein the second angle is not equal to the first angle, wherein the method prior to the step of producing the second breaker ply further comprises the step of turning over the leading part of the rubber band to be cut off, about the longitudinal centre line of the rubber band. producing a first breaker ply having a longitudinal axis, a breaker ply length and mutually parallel cords at a pre-set first cord angle to the
