Latest Patents

One of his latest inventions is the Scrap Scraper. This technology provides an improved means for separating loose scrap from boxes within a layboy, minimizing the risk of flap bending. The design features a distinct intersection of action that addresses issues found in prior art. The shallow scraper funnel, combined with a steep scraper angle of action, allows for effective scrap scraping while avoiding flap bending. Additionally, the flexible scraper facilitates active scrap ejection from the upper side of the box, ensuring efficient removal of loose scrap. The variable board line penetration and scraper stiffness enhance the effectiveness of scrap removal across a wide range of boxes.

Another notable patent is the Scrubber Layboy, which is designed for the transportation of corrugated boxes. This machine incorporates multiple scrap separation devices to improve the efficiency of scrap separation. Key features include a compliant scrap blocker for loose scrap, an opposing phase shift beater for trapped scrap, and a chad wall for stripping various types of trim scrap. The staggered wheel assemblies in the design contribute to reduced order setup time, better board control, and minimized print damage.
