His work has been instrumental in advancing the efficiency and effectiveness of web cutting apparatuses.
Latest Patents
Cogswell holds a patent for a Rotary Web Cutting Apparatus. This invention employs a rotary knife cylinder equipped with elongated, radially outwardly projecting knife blade assemblies spaced around its periphery. A rotary anvil cylinder, which is spaced parallel to the knife cylinder, carries a corresponding peripheral array of elongated anvils. When the two cylinders rotate, the knife blades bear against the anvils at the nip between the two cylinders. The knife blade assemblies are designed to be flexible and resilient, ensuring that each blade edge is biased against its anvil at the moment of interference, providing sufficient local force to cut the web. Additionally, the natural frequency of the knife assemblies is selected to be considerably higher than that of the other machine parts, allowing the spacing between the knife blades and the anvils at the nip to remain largely unaffected by vibrations. This apparatus also efficiently removes trim strips produced by the web cuts.
