1. 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 movement of the core clamping devices axially in opposite directions and for synchronous movement of the turn-over devices axially in opposite directions independently of the core clamping devices, wherein the spindle arrangement has a central spindle and two synchronously running side spindles between which the central spindle extends, wherein the core clamping devices are in transmission connection with the central spindle and the turn-over devices are in transmission connection with the side spindles, or the turn-over devices are in transmission connection with the central spindle and the core clamping devices are in transmission connection with the side spindles, wherein two first spindle nuts are guided on the central spindle, each of the first spindle nuts has at least two first drivers that respectively transmit a driving, force from the spindle nut to one of the devices associated with the central spindle, wherein the drivers are distributed uniformly in a circumferential direction of the drum, wherein the central spindle has two opposing threaded sections, one of the first spindle nuts being arranged on each of the threaded sections, wherein each of the side spindles has two opposing threaded sections, wherein a second spindle nut having a second driver is respectively arranged on each of the threaded sections of the side spindles.
