Title: Innovations by David A. Kearney
Introduction
David A. Kearney is an accomplished inventor based in Keene, NH (US). He holds a total of 6 patents that showcase his expertise in developing innovative solutions for processing materials. His work primarily focuses on improving the efficiency and effectiveness of cutting mechanisms for continuously flowing materials.
Latest Patents
One of Kearney's latest patents is an "Apparatus for cutting a continuously flowing material web." This invention enhances the method for processing a web of material at a constant velocity. The improvements include a cutting mechanism that stops the web using a side surface of a movable blade. Additionally, the design of the web accumulator and cutting speed is optimized to create the right amount of force between the severed end of the web and the blade. This innovation reduces cutting time and modifies cutting force to accommodate different web characteristics, such as splices. A low inertia rotary solenoid is employed to accelerate the blade, which bounces off a resilient stop, returning to its spring-biased home position. This design results in reduced noise and shorter cutting times, allowing for increased web speeds.
Another significant patent is the "Label stacking apparatus." This invention provides methods and apparatus for accumulating, cutting, and stacking continuously moving web materials, such as fabric tape. The system allows for the accumulation of the web between a base and a resilient spring member while other processing steps, like cutting, are performed. The spring member temporarily suspends the tape's forward movement, enabling it to accumulate effectively. The cut labels are then stacked in a bottom-fed assembly, facilitating the removal of processed labels during operation.
