    As illustrated in FIG. 1, an assembled tire cutting apparatus comprises an open sliding protective cover 36, making it possible to display all the elements allowing the cutting of the tires 31. In this example, the pedal 9 makes it possible to initiate a cutting cycle.
    As illustrated in FIG. 2, the apparatus is mounted without its protective cover 36. The apparatus comprises a frame 1 surrounding a reception area 2 receiving a tire 31 ready to be cut. The apparatus as illustrated is not in a normal operating phase because the tire 31 is not held by the lateral holding means 5, 6 (FIG 6). The tire 31 is placed between cylindrical rollers 12 free to rotate about their longitudinal axis. The reception zone 2 slides vertically and is in the high positron for a future cutting operation whereas during the loading of the tire 31 in the reception zone 2, the latter is in a low position to facilitate the handling operation performed by an operator for arranging the tires 31 to be cut in the reception area. A cutting device 8 of a tread of the tire 31, when the tread is separated from its sidewalls, is arranged on the chassis 1, sliding, to cut the tread transversely.
    As illustrated in FIG. 3, the sectional view of the tire 31 makes it possible to visualize the four parts of the tire 31, namely the sidewalls 32, the tread 33, the heel 34, and the inside 35 of the tread.
    As illustrated in FIG. 4, the frame 1 is composed of a box 25 in which can be integrated the entire electrical part, the adjustment block or a supervision tool. The frame 1 further comprises two first horizontal bars 22 located on the upper part of the frame 1, in particular allowing the attachment of two support structures 3 ', 3 "mounted above and on either side of the reception zone. 2 (Fig. 5). Two vertical bars 23 located below the first two horizontal bars 22 for fixing the reception area 2 (Figure 5). Finally, two second horizontal bars 24 for fixing the cutting device 8 (FIG 9).
    As illustrated in FIG. 5, the receiving area 2 for receiving a tire to be cut, in the frame, comprises a pair of horizontal drive rollers 10, 11 of a tire received in the receiving area 2 is placed on the rollers 10 , 11. The reception area 2 is composed of a frame 30 for fixing a first motor 17 which drives in rotation one of the two rollers 10, 11 thus driving the tire to be cut. Four shoes 13 on which is fixed respectively a cylinder 12 free in rotation about its longitudinal axis, to wedge the sidewalls of the tires to be cut. These shoes 13 are fixed to a first guide rail 14 thus making it possible to adjust the maintenance of the tire according to the size of said tire. The frame 30 is fixed in turn to two second vertical guide rails 16 thus making it possible to vertically adjust the height of the reception zone 2 along a support plate 15 which is in turn fixed to the two vertical bars of the frame.
    As illustrated in FIG. 6, the tire cutting apparatus comprises two support structures 3 ', 3 "mounted above and on either side of the reception area, the two support structures 3', 3" being carried by a second support plate 26, fixed on the first two horizontal bars 22 located on the upper part of the frame 1 (FIG 4). This second support plate 26 carries two fourth guide rails 27 for horizontally displacing the two support structures 3 ', 3 "This horizontal movement is triggered by information given by a laser beam emitted by a device carried by the structure of support 3 ', 3 ". This laser beam is parallel to the tread of a tire to be cut. The two support structures 3 ', 3 "carry lateral support means 5, 6 composed on the one hand of a part 5 comprising two branches 37 and two rollers 38 allowing the maintenance of the inside of the tread 35 of the tire to be cut (FIG 3), and secondly a jaw 6 for maintaining the heel of the tire to be cut.The jaw 6 (FIG 7) slides vertically along the support structures 3 ', 3 "to maintain the heel of the tire to be cut according to the size of the latter. The jaw 6 and the piece 5 are diametrically opposed with respect to the inner circumference of a tire received in the apparatus. The jaws 6 and 5 allow to block position in the tires 31 to cut whose inner diameter of the heels varies from 30 centimeters to 60 centimeters. The blades 7 (FIG 8), arranged on each support structure 3 ', 3 ", when they are in the working position, penetrate into the sidewalls of a tire received between the two branches 37 so as to stabilize the zone In this example, the blades 7 are arranged between the two branches 37 of the part 5.
    Another advantage of the use of the jaws 6 and the part 5 is that the device adapts to the dimensions of the tires to be cut, both on the inner diameter of the beads and on the tread thickness which varies from one tire to another and can be between 6 and 35 millimeters. Indeed the part 5, comprising two branches 37 and two rollers 38 for maintaining the inside of the tread, allows to determine accurately the position of the tread of the tire to be cut and thus prevent the blade 7 sinks into the tread.
    As illustrated in FIG. 7, the jaw 6 is fixed on each support structure thus allowing to slide vertically along each support structure 3 ', 3 "to maintain the heel of the tire to be cut.
    In the example illustrated in Figures 9, 10 and 11, the cutting device 8 of the tread of a tire to be cut, when said tread is separated from its sides, is composed of two arms 39 40. The cutting means 8 is arranged on a third support plate 28 composed of two third horizontal rails 19 so as to be able to move horizontally along the two third rails 19. The upper arm 39 carries one of its ends, a pair of coaxial disks 20 spaced from each other, the other arm, lower 40, carrying a substantially circular blade 21 arranged between the discs 20. The cutting device 8 slides to cut transversely the strip when said tread is separated from its sidewalls. A second motor 18 rotates the circularly shaped blade 21 thus making it possible to cut the tread once the sidewalls of the tire have been cut off during the first cutting phase. In this example, the essentially circular blade 21 has several radii of curvature and is beveled.
    Advantageously, the apparatus is arranged so that each blade 7, 21 is lubricated at defined intervals to improve the cutting.
    After opening the protective cover 36, the operator places the tire 31 in the reception area 2 on the two rollers 10,11 and between the four cylinders 12. The tread of the tire to be cut comes into operation. contact with two rollers 10, 11. At this stage, the reception area 2 is in the low position so as to facilitate handling. The operator then closes the protective cover 36 and presses the pedal 9, or any other command such as a push button, to initiate a cutting cycle. The cutting cycle comprises the following steps: - verification of the presence of a tire by a sensor, - wedging of the tire between the cylinders 12, - recovery of the reception zone 2 comprising the tire by a vertical movement up to detection by the laser beam of the central zone, between heels, of the tire to be cut,
