PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF INVENTION
[0001] The present invention relates to a non-destructive tyre section measurement system, and more specifically related to a non-destructive tyre section measurement system and method for testing defects in tyres through non¬destructive tyre cross section measurements of the tyre.
BACKGROUND OF INVENTION
[0002] The tyre industry has recognized for many years that it is useful to examine or test a tyre in a nondestructive manner. This need has been identified both for new tyres, prior to their initial use on a vehicle, and for used tyres, prior to retreading. Thus, it is desirable to detect flaws in the tyre when the tyre is complete with its tread. Various technologies have been suggested in the existing systems to achieve these desirable results, but none has achieved substantial commercial acceptance.
[0003] In an example, in the existing systems, an ultrasonic transmitter positioned outside of the tyre and applies pulses of ultrasound to the tyre at a plurality of locations around the tyre's circumference for transmission through a tyre wall and receipt by an ultrasonic receiver located within the tyre. An ultrasonic receiver generates signals in response to the received ultrasonic transmissions and a computer processes these signals to generate characterizing data from which defects in the tyre may be determined.
[0004] In another existing systems, a support structure receives a tyre and an actuator disposed proximate the tyre for impacting the tyre. A microphone disposed proximate the actuator for receiving a sound wave generated when the actuator impacts the tyre and a computer responsive to the microphone, the computer programmed to calculate a number of discriminator quantities from the resulting sound wave and to compare the calculated discriminator quantities with

stored discriminator quantities indicative of a defect to determine whether a defect is present in the tyre.
[0005] In addition, the measurement process involves visual observation or manual method of determination. Therefore, this test is subjective in nature and not accurate. Further, the tyre testing method has another inherent problem that it may not be possible to test air bubble entrapment defect, presence of foreign material defect, improper curing defect unless the cross section is selected from the area of defect.
[0006] Thus, it is desired to address the above mentioned disadvantages or other shortcomings or at least provide a useful alternative.

Further, the method includes analyzing cross section (cut section) from one end of shoulder to the other end of shoulder. Further, the method includes optionally repeating the same process on different positions of the tyre.
[0053] Unlike to conventional methods and systems, the method can be used to test the defects in the tyres without destroying the tyres by using a probe with specific range of wavelength to measure arrangement of layers within the tyre. The proposed method can be used to eliminate the requirement to physically cut the tyre. The tyre section measurement can happen on the production line. In an embodiment, Pulse Echo Ultrasonic – Non-destructive testing has been coupled with a precision C scan measurement system to map the tyre internal layer profile. This will enable measuring the tyre cross section.

[0054] FIG. 4 is a flow chart illustrating a non-destructive tyre cross section measurement method for testing defects in tyres, according to an embodiment as disclosed herein.
[0055] At step S1, the method includes mounting the tyre onto a mounting apparatus (2). Initially, the tyre is loaded, mounted & clamed on the mounting apparatus (2). A probe trolley is aligned with the mounting apparatus (2).
[0056] At step S2, the method includes immersing a portion of the tyre in a liquid included in the tank (8).
[0057] At step S3, the method includes placing a probe (7) in the liquid on an outside portion of the tyre. The probe (7) is mounted on the XY slides (4 and 5) and is immersed in the water in the tank (8). The XY slides (4 and 5) is actuated to move the probe (7) to a home position (i.e., one end of a tyre cut section).
[0058] At step S4, the method includes determining a cross section measurement of the outside portion of the tyre from one end of a shoulder of the tyre to other end of the shoulder of the tyre based on a signal reflected from at least one layer of the tyre. In an embodiment, the signal reflected from a layer of the tyre is obtained by sending a signal towards the layer of the tyre using a transmitter of the probe (7), and receiving the single reflected from the another layer of the tyre using a receiver of the probe (7).
[0059] At step S5, the method includes placing the probe (7) on an inside portion of the tyre within the liquid. The XY slides (4 and 5) is moved at different points along tyre profile and a probe angle is adjusted.
[0060] At step S6, the method includes determining a cross section measurement of the inside portion of the tyre from one end of the shoulder of the tyre to the other end of the shoulder of the tyre based on a signal reflected from

another layer of the tyre. In an embodiment, the signal reflected from another layer of the tyre is obtained by sending a signal towards the another layer of the tyre using a transmitter of the probe (7), and receiving the single reflected from the another layer of the tyre using a receiver of the probe (7).

[0062] At step S8, the method includes plotting an intensity map of the cross section of the tyre based on the slide position of the X-direction slide (5) and the Y-direction slide (4). Based on the measurement, data is captured for tyre layers and is plotted along the C section. Further, the complete tyre internal image is obtained by moving the probe (7) from one end of cut section to another. The probe response at that point will determine the different layer depths & layer information within the tyre at that point.
[0063] At step S9, the method includes displaying the plotted intensity map for testing defects in the tyre. Based on the obtained complete tyre internal image, the tyre internal geometry measurements is conducted/performed.
[0064] It is to be noted that the probe position along the tyre cross section and probe angle with respect to the tyre cross section can be controlled by the user or automatically by the data acquisition unit. The probe response (includes the signals reflected by the layers of the tyre) along different point on the tyre cross section is determined. The determination of the probe response at a particular point involve placing the probe (7) at an angle perpendicular to the tangent drawn at that point. Further, the probe response at that point determines the different layer depths & layer information within the tyre at that point. The probe response at that point is

plotted as an intensity map on a computer screen to indicate the different layer depths within the tyre.
[0065] Further, unlike the conventional mechanism, the cross section (cut section) from one end of portion to the other end of the portion is measured by plotting the probe response for all the points along the tyre cross section. In an embodiment, measuring the tyre cross section involves determining the geometrical arrangement of different layers within the tyre and determining the layer start and end positions and measuring the layer thickness at particular points within the tyre.
[0066] The various steps described in the FIG. 4 may be performed in the order presented, in a different order or simultaneously. Further, in some embodiments, some of the actions, acts, blocks, steps, or the like may be omitted, added, modified, skipped, or the like without departing from the scope of the invention.

[0069] Signal processing and tyre layer position calculation: received Signal is analyzed in frequency domain to calculate the response from different layers within the tyre. Layer information combined with XY & Angle positions helps us to determine the start and end position of different layers within the tyre cross section / hence enables measurement of layers width ¢ering within the tyre.
