LOUISVILLE, Ky.-A number of companies displayed new products at the recent American Retreaders' Association World Tire Conference. Among them:
Oliver Rubber Co. introduced two tire painters, the ILC II and ILC III.
The ILC II is fully automatic with manual or automatic eject, while the ILC III is semi-automatic with manual eject. The ILC II also automatically adjusts for tire sizes 7.00R15 to 11R24.5 and sprays inside, outside or both as specified by the operator, Oliver said.

The Ultrasonic Tire Analyzer, introduced by Vulcan-Vulcap Industries Inc., detects air leaks, nail hole punctures, tread separations and other defects on unbuffed tires, the company said.
The analyzer uses 18 ultrasonic transducers and receivers to inspect a tire. Robotic arms automatically position the unit's sensors to conform to the tire's shape.
The information is shown on a color monitor and a spray marking system, controlled by the analyzer, marks defects on the tire.
The analyzer can be programed to scan for a desired flaw size.

Hercules Tire & Rubber Co. introduced the Hercules Cement-less Cushion Gum Applicator and the Hercules/CEDCO Tiger 125p Automatic Buffer, made by CISAP.
The gum applicator eliminates the need for using cement in retreading operations by applying heated cushion gum to the casing under pressure. The applicator can service several tread builders at once and can handle all popular light and medium truck tire sizes, Hercules said.
The Tiger 125p is a computer-controlled buffer, capable of finishing truck tires in two to three minutes.
The buffer can be programmed for either cold or hot processing, the company said.
Operators also can program buffed radius, width and circumference, shoulder radius and blade wear allowance.

The Opto R-C-G roller circumference gauge from Opto Electronica S.A. electronically measures a tire's circumference during buffing. The gauge uses a pneumatic arm to keep the sensor on the tire's surface and sends its measurements to a readout that can be mounted on the buffing machine.

McNeil & NRM Inc. introduced an ultrasonic tire tester, manufactured by Technic Systems in England, that detects separations that can't be seen visually.
The system consists of a computer screen, keyboard, ultrasonic generator and a rotating bath tank.
What makes the tester unique is that separations and nail holes can be seen in proportion to their actual size and location, said Don Bibona, manager of engineering at McNeil & NRM.
Results are shown clearly in real world terms and no deciphering is necessary.
The system has no toxic hazards towards the operators and detects more thoroughly than an ultrasonic tester used with an air medium, Mr. Bibona added.

Bridgestone/Firestone Inc. displayed the new Bridgestone M774 drive axle tire designed for logging, refuse and construction-service vehicles.
The M774 has deep original tread depth, an anti-chip/cut tread compound and a split-belt package for flexibility and enveloping.
The M774 comes in sizes 11R22.5 16; 12R22.5 16 and 11R24.5 16.

Piedmont Service Trucks introduced an off-the-road tire service truck that includes an articulating tire service crane operated by a wireless remote control system called CombiDrive.
The A2-250 service truck, which also includes a rotary screw compressor, ``extra large'' tool boxes and a nylon tire hold down system, handles tire sizes from 16.00x25 to 36.00x51.
The CombiDrive remote control system allows the operator to control crane and tire hand movements away from the truck, saving time and improving safety, according to Piedmont.
The Spruce Pine, N.C.-based company also introduced a new air compressor package, called the Vi-per, to support its service trucks.
The Viper features a rotary screw air compressor driven by a 25 hp V-twin, overhead valve Kohler gas engine. The compressor has a six-gallon gas reservoir and electric start and is capable of producing 60 ACFM at 150 psi.
Piedmont said the Viper eliminates the need for a power take off outlet.

Rema Tip Top/North America Inc. introduced the first in a series of tire repair education wall charts for repair technicians.
The charts provide step-by-step instruction on various tire repairs including: one-piece, two-piece and section repairs for passenger/light truck and medium/heavy truck tires.
Rema said the charts include listings of the materials and tools needed for the different types of repairs.
Contact: Rema Tip/Top North America, Dept. TB, 200 Paris Ave., Northvale, N.J. 07647; (800) 225-7362.
Truflex/Pang Rubber Products Co. introduced the Monaflex off-the-road sidewall vulcanizing repair system and a tire repair cement.
The Monaflex sidewall vulcanizing system is portable and can be installed by one man, according to Truflex/Pang Rubber.
It is designed for mid-range OTR tires as well as skidder and Terra tires.
The new repair cement, which is blue in color, dries faster than competitive products, gives increased initial tack and improves the performance in chemical applications, the company said.

Cold Jet Inc. has begun marketing the RDS ``CUB'' Remote Delivery System dry ice blast cleaner to retread shops, according to David Eddy, marketing manager.
The RDS system uses dry ice pellets delivered through a pressurized blow gun to enable employees to clean molds during the production process without disassembly, Mr. Eddy said.
The company said the pellets do not abrade surfaces like traditional ``grit blasting, high-pressure water blasting and most chemical solutions.''
Previously the company produced its cleaning systems for tire and other product manufacturers' molds, Mr. Eddy said.
Contact: Cold Jet Inc., Dept. TB, 455 Wards Corner Road, Suite 100, Loveland, Ohio 45140; (800) 337-9423 or (513) 831-3211.
SemiSystems Inc. displayed a new system for monitoring tire air pressure and wheel temperature on over-the-road trucks.
Called the WMS 100, the system uses a miniature transmitter mounted in the drop center (channel) of the wheel that sends a signal to an on-board computer to notify the driver of changes in air pressures and wheel temperatures while the vehicle is in operation.
