摘要： Tyre drum (1) including a turn-up mechanism for use in building an unvulcanized tyre having tyre components of rubber or provided with reinforcement cords and two bead cores which either may or may not be provided with a bead filling strip, which tyre drum is provided with a central axis (5), two ring segments (6) placed around the axis and spaced apart each for supporting a bead core (3), means for radially expanding the part of the tyre components that is situated within the ring segments, in which the tyre building drum on either side outside of the ring segments is provided with a set of radially extending hinging arms (11), in which each arm is provided with an end oriented towards the ring segment which end has a first turn-up means, such as a first roller (12), means (20) for axially and radially moving each set of arms from a first position in which the first rollers of the set of arms form a virtually closed ring into an expanded second position for pressing the part of the tyre components situated outside of the ring segments against the expanded part of the tyre components situated within the ring segments, in which the arms at the ends near the first rollers are provided with moveable support surfaces (15) which in the first position form a virtually closed cylindrical surface for supporting the tyre components.
