<p>A device is disclosed that can remove the side wall from a tyre carcass. A movable table (4) is fitted to a pivoting support (3). A shaped arm (29) is attached to the table (4) and ends in a tapered portion (13) which terminates with two rollers (9a,b). A powered disk blade (14) is positioned on the device such that, when in use, the blade (14) can penetrate through the side wall of the tyre carcass. At the end of the table (4) which faces the rollers (9a,b) there are positioned a set of powered rollers (10). A tyre carcass (15) is positioned on the table (4) and then the table (4) is positioned to allow the rollers (9a,b) and the tapered portion (13) to spread apart the beads (17a,b) while positioning the rollers (9a,b) within the interior of the tyre carcass (15). The table (4) is then re-positioned whereby the rollers (9a,b) engage the interior surface of the tread of the tyre carcass (15). The drive rollers (10) are then positioned against the outer surface of the tread. The cutting blade (14) is then moved upwards to commence cutting through the side wall of the tyre carcass (15). The rollers (10) rotate the tyre carcass on the table (4) until the cutting blade has completed an annular cut of the side wall. The drive rollers (10) are retracted and the table is then returned to its original starting position.</p> |
