Patent number: 10994876Abstract: An automated wrapping technique for vehicle components is disclosed. A component to be wrapped is secured to a fixture, which in turn is coupled to an actuator. A grabber arm grabs a length of wrap from a feed roll. The grabber arm removes the backing and spreads the wrap over the component. The actuator pushes the component upward until the wrap contacts the component surface. An applicator may concurrently smooth the wrap and evacuate trapped air. The wrap may be cut around the periphery of the component, and hemmed. A controller provides instructions to automate the wrapping mechanism.Type: GrantFiled: June 18, 2018Date of Patent: May 4, 2021Assignee: DIVERGENT TECHNOLOGIES, INC.Inventors: Jon Paul Gunner, Alex James Hamade, Narender Shankar Lakshman, Stuart Paul Macey
