A machine suitable for using in disintegration of rubber tyres comprising a support 12 for mounting a tyre 10 for rotation about a first axis A, extending in a direction from front to rear of the machine, first and second abrading tools 14 mounted for rotation about second and third axes parallel with the first axis and at opposite sides of the first axis, means mounting each tool for movement lengthwise of its axis of rotation to and fro between a retracted position and an advanced position wherein the retracted position of the first tool is at a rear portion of the machine, the retracted position of the second tool is at a front portion of the machine and the advanced positions are at a central portion between the front and rear portions of the machine, the advanced positions of the first and second tools overlapping when considered in a direction lengthwise of the first axis, the machine further comprising means for mounting the tools for movement towards and away from the first axis. A sensor 26 detects when the metal centre of the tyre is reached to terminate the abrasion action. |
