ABSTRACT:
The tire-building drum comprises alternate drum sectors with fixedly and movably mounted shoulders and mechanisms for moving said drum sectors. Each of these mechanisms consists of two parts having annular slides, which are connected to a screw drive, and levers, which are articulated to the drum sectors and the slides and which have toothed sectors arranged in constant mesh with each other for the purpose of inter-connecting the parts in each of the mechanisms for moving the drum sectors. The slides are mounted coaxially on the drum hub and are adapted to move together and separately in mutually opposite directions. This enables the drum sectors to move only radially and decreases the axial dimensions of the drum.
