Barbco’s Revolutionary FlexBor is Now Patented
February 24, 2020 by NASTT Staff
Barbco, Inc. Co-Owner and CEO, Anthony R. Barbera was granted U.S. Patent #10465460 for the Barbco FlexBor tooling and technology on November 5, 2019. This is a proud moment in this East Canton, Ohio manufacturer’s storied 30-year history of driving the trenchless technology, horizontal boring, and underground manufacturing industries forward with world class capital equipment and cutting-edge technology. The FlexBor is an extremely cost-effective, environmentally safe trenchless method and tooling. The FlexBor is designed to virtually eliminate “frac-outs” / ”inadvertent returns” that are often associated with horizontal directional drilling and the use of bentonite.
The Patent Abstract reads: “A cutting assembly and method for drilling an underground borehole. The cutting assembly includes front and rear cutting heads of different diameters mounted on a shaft. An air passage defined through the cutting assembly may be placed in fluid communication with a pressurized remote air source and with a bore of a casing extending rearwardly from the cutting assembly. Pressurized air flows through the air passage and entrains cuttings produced by the front and rear cutting heads. A housing extends rearwardly from the larger diameter rear cutting head and an auger provided within the housing aids in directing cuttings into the casing. The auger rotates independently of the rest of the cutting assembly and may be configured to further reduce the size of the cuttings. A collar on the housing seals the borehole cut by the rear cutting assembly and aids in preventing frac-out.”
