<p>The invention relates to a device for inspecting the inner surface between first and second beads of a tire (P), including means for acquiring an image of the inner surface of a tire (1), and centering means capable of locking the first bead over the entire circumference thereof on a reference plate, and driving the tire into relative rotation about the XX' axis thereof relative to said image acquisition means. The device includes means for opening and holding the second bead, which comprises two inner holding rollers (32, 32) having a substantially radial axis, and at least one outer holding roller (33) having a substantially radial axis, which are arranged substantially in the middle of the angular sector formed by the two inner holding rollers (31, 32) and are capable of bearing on the outer portion of said second bead, wherein the inner (31, 32) and outer (33) holding rollers are mounted so as to be rigidly connected in rotation relative to the axis XX' of said image acquisition means (1).</p> |
