Abstract: A radially expandable building drum, in which is intended for manufacturing an adapter for mounting a tire on a wheel rim, includes a central shaft, a first set of segments, and a second set of segments. All of the segments are arranged circumferentially around the shaft to form a generally cylindrically shaped external face of the drum. The segments of the first set and the segments of the second set face one another axially. The drum is structured to allow a different radial expansion of the segments of the first set in relation to the segments of the second set, between two working positions.

Abstract: A crown reinforcement of a tyre includes at least one crown triangulation belt having a given width value (R). The belt essentially includes elementary widths each having a given width value (B). Each of the elementary widths has a flattened cross section and forms an angle (?) with a circumferential direction of the tyre, the angle (?) being between 10° and 80°. Adjacent elementary widths, which are positioned directly next to each other, are separated by a groove of a given width value (j) and are connected to each other by one or more weak bridges.

Abstract: A method for assembling a green tire blank includes, in succession, laying rubber plies on a drum having segments that are radially moveable, with respect to a main axis, between expanded and collapsed positions; laying bead wires; lifting up edges of the plies that extend axially beyond the bead wires towards ends of the drum using wings that extend axially and that are arranged circumferentially around the main axis; and folding the edges of the plies using rollers. The segments form an external circumferential face of the drum. The rollers are independent of the drum and move in an axial direction on the circumferential face of the drum in order to turn the edges of the plies around the bead wire. The wings move in longitudinal cuts that run parallel to the main axis at ends of the segments in order to lift up the edges of the plies.

Abstract: A method for manufacturing a tire involves successively performing steps that include: continuously converting a flat reinforcing strip into an undulating reinforcing strip; pressing peaks of waves of the undulating reinforcing strip one by one onto a surface of a tire blank that is driven in rotation by a drum about a drum axis; and winding the undulating reinforcing strip onto the tire blank. In the converting step, the flat reinforcing strip is converted into the undulating reinforcing strip in an immediate vicinity of the drum. The waves of the undulating reinforcing strip and movement of the peaks of the waves of the undulating reinforcing strip towards the surface of the tire blank extend in a plane substantially perpendicular to the drum axis.
