Bale wrap removal device utilizing shape memory wire

Abstract:

A wrap removal assembly includes an elongated support member extending along a central longitudinal axis and having an exterior surface. A snagging wire is disposed adjacent the exterior surface of the elongated support member and includes an active material changeable between a first shape and a second shape in response to a control signal. The snagging wire presents a catch spaced outward and away from the exterior surface when disposed in the first shape to snag the wrap material and gather the wrap material around the elongated support member. The snagging wire is positioned substantially flat against the exterior surface of the elongated support member when disposed in the second shape to release the wrap material and allow removal of the wrap material from the elongated support member.
