High Speed, Non-Contact 3D Laser Scanning in the Rubber & Tyre Industry
- By 0
- May 06, 2020
Rubber presents a challenge for optical-based measurement sensors. By nature, the black surface is difficult to capture reliable data from and accurately measure. This challenge is often intensified by the complex shapes into which rubber derivatives are extruded or molded.
As a solution to this challenge, 3D laser sensor manufacturers have optimised the design of their sensors to successfully implement scanning and quality control functions for both in-process and final product inspection applications in rubber and tyre manufacturing.
3D laser scanning
Rubber material comes in two forms on the production line, either as fresh and uncured from an extruder or a calender, or as a finished product (e.g., vulcanised tyres). Non-contact 3D laser scanning offers the most practical solution for inspection of both of these rubber material types.
Here’s why:
- The soft, gummy nature of the rubber makes contact-type measurement ineffective. This measurement approach is also too slow to keep up with the high-speeds of continuous web material production.
- 2D sensors require complex lighting to see black-on-black contrast. In some applications the lighting is placed underneath the material (e.g., when measuring the width of a strip), and hot sticking rubber can contaminate the lights. In addition, 2D can’t produce measurements related to object geometry (i.e., 3D shape), which means they are unable to measure critical features such as object flatness, surface angles, or part volumes, and are limited to contrast-based inspection. This makes 2D sensors a poor solution for scanning complex shape-based features on dark surfaces, or for operation in low lighting conditions.
3. In comparison, 3D laser sensors are contrast invariants and generate high-resolution scans regardless of the material or lighting conditions. They also capture the complete 3D geometry of the scan target, including critical depth measurements on surface features such as grooves in a tyre tread. 3D laser sensors are also able to achieve the high speeds required for continuous web material scanning.

Laser profile sensors provide an ideal solution to both in-process and final rubber and tyre measurement and quality control applications. Built-in measurement tools for strip positions, including multiple groove location and depth measurement monitoring with automated alignment enable engineers to configure setup parameters––without requiring any measurement software development.
In addition, the ability to store multiple geometry configurations in the sensor makes changes between different recipes quick and simple, which is critical in minimising downtime for operations that make model changes multiple times per shift.
Application examples
- In-Process Inspection
Extrusion Profiling with High-Resolution Gocator® 2440 Laser Profiler
Extruding rubber in a specific shape makes up the tread portion of a tyre. Measurement of the extrusion profile is carried out in-process, correcting the extrusion parameters in real-time to maintain the required shape. Key measurement parameters include thickness, width, and profile. Another required sensor capability is monitoring the position of surface features, such as ridges, center lines, and edges.
Profiling these tread extrusions is done by using 3D laser sensors to scan across the extrusion, generating a profile to which built-in measurement tools and pass/fail decision-making logic can be applied.
In this example, two Gocator 2440 laser line profilers are used to measure the rubber web’s extrusion groove pattern, geometry, and location with an X resolution down to 13 microns. Gocator 2440 sensors are able to inspect multiple grooves in a single setup, and groove measurements are unaffected by changes in surface angle relative to the sensor.
Most importantly, Gocator 2440 sensors generate critical 3D height data for robust shape measurement. 2D solutions are limited to contrast-based inspection.
- Final tyre inspection
Tyre Sidewall Inspection with High-Speed Gocator 2530 Laser Profiler
scanning extruded tyre tread
Traditional methods for measuring tyre sidewalls for defects such as bulges and dents suffer from too many false rejects (i.e., classifying a good tyre as defective). Due to measurement system limitations, many manufacturers have no choice but to “oversensitise” their sidewall bulge and dent measurement systems, resulting in costly manual inspection requirements for all rejected tyres.

In fact, some measurement systems cannot even distinguish between bulges or dents. However, with state-of-the art laser measurement precision and advanced built-in software analysis, false positive rates can be substantially reduced and, in many cases, eliminated altogether.
Using a Gocator 2530 laser profiler the engineer is able to generate full surface point cloud geometry data in order to detect small defects (down to 28 microns X resolution) anywhere on the sidewall surface. The sensor also delivers complete scan, measurement, and control at 4 kHz, allowing engineers to meet stringent cycle time requirements––with no need for industrial PCs or external controllers.
In this configuration, two profile sensors are typically used, one for each sidewall (top and bottom buddy system). A third sensor is often used to monitor radial runout of the tread.
Leveraging 3D Laser Scanning and Inspection
pattern, geometry, and location
Laser-based laser triangulation sensors meet the high speed and high resolution requirements for accurate rubber and tyre measurement. These sensors are used in a variety of in-process and final inspection applications, including extrusion profiling and tyre sidewall inspection.
Adding 3D laser sensors for automated quality control is vital to reducing scrap and rework, and improving final product quality by maintaining consistency throughout the tyre manufacturing process.

A new milestone in agricultural tyre technology has been achieved through the partnership of Titan International, Inc. and Cerebrum Sensor Technologies, Inc. Together, they have unveiled Titan Pressure Perfect (P2), a smart sensor system designed to transform how farm tyres perform and communicate. This system marks the emergence of a broader category known as Intelligent Tyre Solutions (iTS), developed jointly by the two companies.
At the core of Pressure Perfect (P2) is real-time monitoring of tyre pressure, temperature and load. This data enables continuous oversight and works seamlessly with onboard inflation systems, allowing automatic pressure adjustments while the vehicle is in motion. Whether shifting from roadway to field or responding to varying load demands, the system can reduce air pressure by as much as half. This flexibility helps lower soil compaction by up to 35 percent and has been linked to potential corn yield increases of four to six percent.
Pressure Perfect is compatible with all Titan and Goodyear Farm Tyre products and integrates with nearly all inflation management systems already in use. By supporting more precise tyre management, it contributes to longer tyre life, improved machine efficiency and reduced environmental impact through less ground disturbance.
The innovation draws on Cerebrum’s licensed portfolio of patented technologies, including advanced sensors, proprietary algorithms and sophisticated software capabilities. This technical foundation sets a new standard for intelligent tyre management in agriculture. While other industry players focus on replicating existing central tyre inflation and tyre pressure monitoring systems, Titan and Cerebrum are advancing a more comprehensive and forward-looking approach. Pressure Perfect reflects Titan’s longstanding engineering heritage and its continued commitment to leading the field through purposeful collaboration and applied innovation.
Dubbing it the ‘Holy Grail’ of innovations, Scott Sloan, Global Ag & LSW Product Manager for Titan, said, “This is the first system of its kind that delivers dynamic inflation management. Load, tyre pressure and temperature data are gathered by a single tyre-mounted sensor and integrated with tyre-industry load-inflation tables in real time. Imagine bringing together Central Tyre Inflation System (CTIS) and Tyre Pressure Monitoring System (TPMS) technologies, and now they can work together and talk to each other – all without operator intervention."

Continental Innovates Tyre Technologies For Quieter Driving
- By TT News
- January 30, 2026
As urban areas around the world grow increasingly louder, traffic noise has emerged as a critical environmental and public health challenge. Recognised by health authorities as a major risk factor, this pervasive issue extends from European cities to megacities across Asia and Latin America. Continental is addressing this problem by pioneering tyre technologies that significantly reduce rolling noise, thereby contributing to quieter urban environments and enhanced in-vehicle comfort.
The transition to electric mobility has brought tyre noise into sharper focus. With the near-silent operation of electric motors replacing traditional engine sounds, the acoustic contribution from tyres becomes far more prominent, even at moderate city driving speeds. In response, Continental engineers have developed specialised solutions that target noise generation without compromising the safety, durability or performance of the tyre.
One such innovation is the Silent Pattern tread design, featured on models like the EcoContact 7. This technology disrupts the conventional, uniform arrangement of tread blocks that typically creates a rhythmic humming sound on pavement. By intelligently varying the spacing and angles of these blocks, the pattern breaks up this acoustic consistency. Furthermore, it is tuned to cancel out specific sound frequencies, akin to the principle behind noise-cancelling headphones. This results in a measurable reduction of traffic noise at speeds around 50 kmph, where rolling noise is most perceptible to pedestrians and residents.
For reducing noise inside the vehicle cabin, Continental employs its ContiSilent technology. This involves lining the inside of the tyre with a lightweight polyurethane foam that absorbs vibrations caused by the tyre’s contact with the road. By dampening these air vibrations, the technology can cut perceived in-cabin rolling noise by up to nine decibels – a reduction the human ear experiences as nearly halving the volume. This substantial increase in acoustic comfort is integrated into various product lines, including high-performance summer tyres, without affecting driving dynamics or efficiency.
The company’s commitment to low-noise mobility spans multiple vehicle segments. From the Conti Urban NXT for city buses to passenger car tyres like the EcoContact 6 Q and van tyres such as the VanContact A/S Eco, these products are designed to meet stringent noise standards. Consumers can readily identify these quieter options through regulatory labels, like the EU tyre label, which provides clear decibel ratings for external rolling noise. Through these continuous advancements in tread design and sound-dampening materials, Continental is systematically working to diminish the acoustic footprint of road traffic.
According to Achillefs Tsotras, head of Continental’s Tyre-Vehicle Interaction department, “Noise, especially traffic noise from cars, buses and delivery vehicles, is a major burden for people and the environment. With tyre technologies like ContiSilent and innovative tread designs, we are actively reducing rolling noise without compromising safety. This makes every ride noticeably quieter, benefiting drivers, pedestrians, residents and the environment alike.”
