- the central portion of the flank 2a is traversed by the device 47 'and the hook 6 is located at the rod.
- FIG. 18c illustrates the locking device 47 'in the working position.
- the front portion 71 of the locking element 48 is actuated by a hydraulic jack 84 and pivots around a hinge 72 of horizontal axis of a cradle 73 to block the side 2a bearing against the plate 22
- the blocking element 48 thus holds the sidewall 2a
- the upper end of the front portion 71 is closest to the hook 6 in order to firmly hold the sidewall at the place where the force is applied. uprooting.
- the hook 6 can be actuated to perform a relief.
- Figures 13 to 17 illustrate for their part a variant of the movable element 9.
- the movable element 9 comprises an additional hook 54.
- This additional hook 54 is pivotally hinged (relative to a fulcrum 46) to rotate between two extreme positions (one represented on the Figure 13 and the other shown in Figure 15).
- the additional hook 54 is movable in a direction D3 perpendicular to the direction D1 of movement of the hook 6. It should be noted that this hook 54 is movable in this direction D3 between two extreme positions, shown respectively in FIG. 13 (first position) and 16 (second position).
- the machine 1 therefore preferably comprises handling means (not shown) of the additional hook 54 in the direction D3.
- the machine 1 also comprises means 45 for actuating the additional hook 54 in rotation.
- the means 45 for actuating the additional hook 54 in rotation comprise a shaft 55a (to which this other hook 54 is connected) and a drive 55b (which may be an electric motor or similar device).
- this other hook 54 is guided in the direction D3 by means of a slide 51, which extends in this direction D3.
- Figures 13 to 17 illustrate the stall sequence of the cable 32 of the hook 6 by means of the additional hook 54.
- the hook 54 is rotated in an extraction direction W1 and, after going to meet the cable 32 in position P3, it raises and detaches the hook 6. [099] After detaching the cable 32 of the hook 6, the additional hook 54 holds the cable 32.
- Figure 15 illustrates a movement of the hook 6 in the direction D1 to cause the hook 6 out of the overall dimensions of the action zone of the additional hook 54, until it reaches the position P2 '. Following this operation, it is then possible to rotate the additional hook 54 to release the cable 32. To this end, the hook 54 is rotated in the direction W2 inverse of the direction of rotation W1 previously described for reach the position P4, so as to release the cable 32 ( Figure 17).
- it is intended to move the additional hook 54 in the direction D3, away from the hook 6, so as to release the cable 32 at the predetermined release zone.
- the additional hook 54 preferably comprises a pair of fastening elements (44a, 44b).
- these attachment elements (44a, 44b) are spaced from each other in the direction D3 by a distance S1 greater than the thickness S2 of the hook 6 in this direction D3: so that, during the rotation in the hooking direction W1 of the cable 32, these hooking elements (44a, 44b) are arranged on either side of the hook 6 and do not interfere with the hook 6 during rotation.
- An advantage of the invention is to provide a machine 1 for separating the steel heel reinforcing cable 32 from the sidewall of a tire which is very thin. flexible, that is to say able to work with tires of various sizes and which is, in particular, able to perform the relief even with heavy tires.
- Another advantage of the invention is to provide a machine 1 which is very safe for the final operator: indeed it will be noted that in this machine 1, the intervention of the operator is simply limited to order the machine 1 and, except exceptional events, the operator does not have to manipulate the cable 32 extracted.
- this machine 1 is particularly safe is of considerable importance if we consider that the machine 1 itself is able to treat particularly bulky tires and, therefore, the dangers related to the dimensions and the forces involved are greater than those of known type machines.
- the present invention further defines a method of extracting a metal cable 32 from the sidewall 2a of a tire 2, said cable 32 constituting the support structure of said tire 2, which method comprises the steps of :
- the method further comprises the steps of:
- the cable extraction operations can then proceed identically to those described for the extraction of the cable 32 located on the side of the flank 2a.
