Positively Mark Defects:

When combined with appropriate machine vision web inspection technology, the RKB Model 1280 Guardian® Multicolor Edge Marking™ Technology makes it possible to positively identify defect types and/or locations in a variety of web based materials. Up to five standard colors of water based, re-pulpable inks can be applied by means of atomizing systems to form a controlled mark along the web edge. Additional colors can be applied depending on your overall application. Additionally, any type of ink can be utilized in our spray marking technology provided it is liquid form.

Achieve Automatic Control:

Marks produced by the RKB Model 1280 Guardian® Multicolor Edge Marking™ Technology are detectable with a variety of on-line sensors for automated control of subsequent processing machinery such as winders, slitters, sheeters and coaters. These marks are also visually pronounced as concentric circles on the outside edge of the material roll for corrective patching or splicing of defective areas, sorting or grading decisions. Our spray marking technologies can be integrated with RKB "Auto Break" technologies to ensure complete automatic control capabilities.

Track Edge of Web Motion:

Solid state laser sensing technologies are used for corrective web edge tracking up to 12" (30.5cm) of web travel in the cross machine direction. This prevents potential damage to the web and ensures that marks are placed only on the edge of the web material. The spray head assembly will automatically retract during web break conditions and advance upon detection of web material. Our spray marking technology can also be retracted or advanced under manual control for setup operations.

Prevent Product Contamination:

Each spray head assembly is equipped with an overspray collection system that completely encloses the atomizing spray systems preventing potential coloration of good web material. The collection system also prevents any atomized ink from entering the production environment.


Choose A Complete System:

The RKB Model 1280 Guardian® Multicolor Edge Marking™ Technology includes a marker control station which contains the system's control electronics, power supplies and operational verification systems. Our marking system also includes a complete spray head assembly, main body assembly configured for the desired number of inks required, a test station, overspray collection system, and a water and air purification system. Ink is delivered through gravity controls to electronic and pneumatic control technologies for accurate, consistent, and reliable operation.
