APV’s tread striping inks are offered in both water-based and solvent-based chemistries for various rubber substrates. The inks are typically used in OEM after the tire tread is extruded in an uncured state and functions to mark the centerline of the tread or to provide color coded stripes for identification purposes. Tread striping ink is also incorporated in other rubber manufacturing processes including the production of automotive belts, sheet rubber, and industrial hose and tubing.
Offered in a variety of colors and viscosity ranges, the formulations are engineered to remain solid and bright, even after curing, and do not produce mold fouling. Solvent-based formulations are co-curable, fast drying and contain no hazardous air pollutants (HAPs). Water-based formulations are free of volatile organic compounds (VOCs) and comply with EPA guidelines. Our development team can formulate custom colors or accommodate unique performance specifications for large projects.
APV has a full-service engineering team for customized equipment design and installation.

Tread Striping Equipment
APV Engineered Coatings offers 3 different systems to apply both our solvent based and water based tread striping inks. These systems consist of a Beugler Wheel®, a Capillary Pressure System and a Capillary Gravity System. An APV representative will recommend a system based on a number of variables such as striping amount, tread temperature, dry time, and distance from application to cooling.
APV’s Beugler Wheel® striping system consists of a bottle of tread striping ink with a Beugler Wheel® cap. The bottle is placed upside down in a holder with the Beugler Wheel® cap against the tread. As the tread moves, it rotates the wheel allowing it to pick up the ink inside the bottle and transfer it evenly onto the tread. The Beugler Wheel® heads are available in a variety of sizes and pitches to allow different stripping widths and transfer amounts.
The APV Capillary System can either be gravity or pressure fed. In either system, the tread striping ink is transferred through a capillary tube to a blunt needle. As the tread is running, the needle is laid against it allowing ink to transfer through it onto the tread. The result is a solid line without variation in width or thickness.
The APV Capillary Gravity System is ideal for production lines that go through a minimal amount of ink per day. It consists of a bottle holder, a gravity feed cap, and a control panel. Bottles are placed upside down in the holder with the gravity feed cap attached. The tubing in the cap then hangs down and the needle is secured in place by a holder. Ink is supplied to the needle through gravity, but still maintains the same flow rates as the Capillary Pressure System. Should the conveyor running the tread stop for any reason, a control panel tied into the conveyor can automatically shut off the system.
APV’s Capillary Pressure System is ideal for production lines that apply a high amount of ink per day. It consists of ASME pressure tanks, an air pressure manifold, an ink pressure manifold, and a control panel. Striping ink in the tanks is pressurized by the air pressure manifold, which then sends the ink through the capillary tubing to the ink manifold. The ink is then fed to the needle, and transferred to the tread. In addition to the air pressure manifold, each color in the system is also independently controlled by an extra sensitive regulator to increase or decrease pressure. These changes in pressure will in turn increase or decrease the flow rate of the ink. Should the conveyor running the tread stop for any reason, a control panel tied into the conveyor can automatically shut off the system.
