Abstract

A device is disclosed for turning up the side walls of tyres on a shaping drum for shaping a tyre carcase, the spindle arrangement of which has a central spindle and at least two side spindles running in parallel, between which the central spindle extends, wherein the central spindle and the side spindles are drivable in a mutually independent manner and the core clamping devices are allocated to the central spindle and the turn-over devices are allocated to the side spindles or the turn-over devices are allocated to the central spindle and the core clamping devices are allocated to the side spindles.

Claims

1-10. -10. (canceled)

11. An apparatus for turning up tire side walls on a shaping drum for shaping a tire carcass, comprising:

two core clamping devices;

two turn-over devices; and

a spindle arrangement for synchronous axial movement of core clamping devices in opposite directions and for synchronous axial movement of the turn-over devices in opposite directions independently of the core clamping devices, wherein the spindle arrangement has a central spindle and at least two synchronously running side spindles between which the central spindle runs, wherein the core clamping devices are assigned to the central spindle and the turn-over devices are assigned to the side spindles, or the turn-over devices are assigned to the central spindle and the core clamping devices are assigned to the side spindles.
