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.

Turn-up device for tyre side walls

The method and the device serve for aligning a belt strip, which has a middle part and triangular end pieces. The belt strip is wound onto a tire building drum in such a way that the triangular end regions extend next to one another, at least in certain regions. At least one of the triangular regions is changed in its alignment, at least in certain regions. This achieves the effect that the triangular regions extend next to one another on the tire building drum with matching edge contours

Method and device for aligning a belt strip

A pressing roll for a tire building machine includes a shaft having a longitudinal axis; a plurality of discs inserted on the shaft in an axial series; a mounting arrangement for providing for an individual, radial displaceability of each disc relative to the longitudinal axis; and a force-exerting power arrangement for displacing the discs relative to the shaft.
