Abstract: A method for depositing at least one colored layer on the surface of a vulcanized tire sidewall includes applying by inkjet a colored layer to the whole of the sidewall or to at least a part of the sidewall of the tire and then, after drying, selectively removing the colored layer in such a manner as to create a first pattern. A tire obtained on completion of that method is also disclosed.

Abstract: A drum is provided for building a green tire casing. The drum includes sectors, an expander, and an adjuster. The sectors form a circumferential face of the drum. The expander moves the sectors in a radial direction such that, at any given time, all the sectors extend at a same distance from an axis of the drum. The adjuster moves the sectors in the radial direction separately from movement of the sectors caused by the expander. Movement of the sectors by the adjuster is such that, at any given time, all the sectors extend at an equal distance from the axis of the drum. The expander is usable to move the sectors regardless of a position of the sectors caused by an operation of the adjuster.

Abstract: The drum (2) for building a green tire casing comprises: sectors (8) that form a circumferential face of the drum, expansion means (40, 36, 28, 30, 32) that are able to move the sectors in a radial direction such that, at any time, all of the sectors extend at one and the same distance from the axis, and adjustment means (12, 22) that are separate from the expansion means and are able to move the sectors in a radial direction such that, at any time, all of the sectors extend at one and the same distance from the axis. The expansion means are usable regardless of a position of the sectors under the effect of the adjustment means.
