Tyre building drum with turn-up apparatus

摘要

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. Each arm is movable from a resting position to a working position. A set of bead support members is disposed about the central axis. The bead support members have a support portion. When the arms are in the working position and the bead support portions are in the support position, the support portions cooperate with the ends of the arms to support the turn-up portion of the tire-component therebetween.
