Title: **Innovative Contributions of David S. Knudsen**
Introduction
David S. Knudsen, an accomplished inventor based in St. Louis, MO, holds an impressive portfolio of 11 patents. His contributions have significantly impacted the efficiency of bag tying machinery, showcasing his expertise in mechanical innovation.
Latest Patents
One of Knudsen’s latest inventions is a sophisticated machine designed for applying twist-type ties to the necks of bags. This innovative machine features a defined path and sets of endless belts that converge at a nip, propelling the bag neck forward into the tying zone. The process involves a twist-type ribbon that crosses the path and is secured to a holder, enabling effective bag sealing. An endless chain transports a pusher tab that gathers the bag neck and deflects the ribbon. During a crucial pause, a bag clamp holds the bag neck in place while a needle elevates a segment of the ribbon to form leading and trailing segments beneath the gathered neck. This procedure allows a twister hook to efficiently twist together the segments, and as the tie concludes, the holder shears the trailing segment while maintaining its position across the path. A ribbon stripper then clears the tying zone, ensuring the machine operates seamlessly.
