A machine for manufacturing tires (P) using at least one core (N) used as a reference surface of the manufacture of the tires (P) by moving consecutively from one manufacturing station to another from the start of assembly through to vulcanisation, comprising a first line of stations, oriented in a horizontal direction XX', capable of receiving the core whose axis of rotation rr&#x2032; is oriented horizontally, and a second line of stations (&#x2032;), oriented in a horizontal direction YY&#x2032;, perpendicular to the direction XX&#x2032;, in which the stations are capable of receiving a core (N) whose axis rr&#x2032; is oriented vertically. The first line of stations comprises a first () and a second () station for assembling the tire including member () for grasping and driving the core (N) in rotation about a horizontal axis rr&#x2032;, merged with the axis XX&#x2032;, such members being placed opposite one another. A turning device () is movable in the direction XX&#x2032; and is capable of transferring the core from one station to another within the first line of stations () by making the axis rr&#x2032; of the core effect a translation along the axis XX&#x2032; and a rotation of 180&#xb0; about a horizontal axis yy&#x2032; parallel to the direction YY&#x2032;.
