  • Patent number: 10683113
    Abstract: A device and corresponding systems and methods are provided for wrapping an object resting on an object conveyor defining an object path, the object conveyor conveying the object in a forward direction along the object path, the device comprising: an orbital wrapping mechanism configured to travel in an elliptical path around the object path and to deposit a stretch wrapping material; a wrapping material conveyor configured for cooperation with the object conveyor, the wrapping material conveyor positioned beneath the object conveyor such that when the orbital wrapping mechanism travels along the elliptical path, the orbital wrapping mechanism deposits the stretch wrapping material around both at least a portion of the object and at least a portion of the wrapping material conveyor, the wrapping material conveyor having at least one bearing surface in contact with the stretch wrapping material and movable in a forward direction such that the stretch wrapping material is conveyed along with the object in the f

  • Patent number: 10287043
    Abstract: Apparatuses and methods are provided in relation to a wrapping machine for wrapping packages, and more particularly, to a film-breaking apparatus for use with a wrapping machine having a dispenser carriage movable along a wrapping axis for wrapping a film around a package. The film-breaking apparatus includes a trigger arm coupled to the dispenser carriage; a puncturing arm including a puncturing member, the puncturing arm pivotably connected to the trigger arm such that the trigger arm is free to rotate relative to the puncturing arm in a first rotational direction, and rotationally coupled to the puncturing arm in a second rotational direction. The puncturing arm is configured to puncture the film being dispensed by the dispenser carriage with the puncturing member when rotated by the trigger arm.
