Abstract

The tyre building drum has a series of curved, overlapping split screens, which extend radially outwards relative to the drum segments, and are provided, at their centres, with radial valve rods in sliding contact, in the radial direction, with peripherally distributed hollow spokes, at least some of the split screens possessing radial guides, which can slide radially along the spokes, and have eye bolts for hooking onto the tension springs for inwardly drawing the split screens.
