Abstract: 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 o

Abstract: The present invention relates to a tire building drum. The drum has a central axis and is configured for turning up a turn-up portion of a tire component about a bead core. The drum includes a first support member, which is disposed radially about the central axis and is configured to operably support a portion of the tire component and the bead core. A set of arms is disposed about the central axis. The arms have a first end operably associated with the first support member and a second end spaced apart from the first support member along the central axis and pivotably associated with the tire building drum.
