Abstract

Annular tyre heel wire is placed on a radially deformable drum of a tyre producing machine by (a) placing the wire over the periphery of a fixed, centring ring, coaxial with the drum, in order to centre the wire relative to the drum, (b) laterally seizing the wire at several points on its circumference, and displacing it axial, while maintaining it in the centred state, to lead it into a predetermined position along the drum, and (c) radially expanding the drum towards the exterior in order to place it against the inside peripheral part of the wire. The heel wire remains firmly centred during its placement on the drum. Modified wires e.g. with flappers, can be easily placed on the drum.
