摘要： A self-propelled wrapping machine movable on a supporting surface includes a self-propelled carriage provided with a drive wheel for moving the self-propelled wrapping machine and a lifting device having a supporting element provided with an idle auxiliary wheel associated with the carriage and selectively movable between a raised position, where the auxiliary wheel is spaced from a supporting plane, and a lowered position, where the auxiliary wheel abuts the supporting plane and lifts and detaches the drive wheel from the supporting plane. The supporting element is rotatably associated with the carriage to rotate between the raised and lowered positions. The lifting device has a lever rotatably supported by the carriage, connected to the supporting element by a connecting element and movable between a non-operating position and an operating position, where the lever arranges the supporting element respectively in the raised and lowered positions.

摘要： A wrapping machine for wrapping material around a load includes a wrapping unit to wrap a portion of the material around the load and a supplying unit to supply the material portion to the wrapping unit. The wrapping unit includes wrapping device to unwind the material portion from the supplying unit and wrap it around the load. The wrapping unit includes a supporting ring, rotating around a wrapping axis and provided with a plurality of wrapping rollers, and an unwinding arm having a first end rotatably fixed to the support ring and a second end supporting at least one unwinding roller to abut and guide the portion of material towards the load during wrapping. The unwinding arm is movable to move the unwinding roller to/from the load during wrapping.

摘要： A locking device associable to a wrapping machine for locking in a defined locked position a wheeled load to be wrapped with a plastics film, the locking device including a first element elongated along a first direction and arranged to rest on, and be fixed to, a supporting plane of the wrapping machine, and a second element connected to the first element. The second element is provided with a seat open on the supporting plane and includes an inlet opening for allowing a first wheel of the wheeled load be inserted into, or disengaged from, the seat along an insertion direction, and a recess arranged to be engaged by the first wheel in the locked position so as to prevent the first wheel from moving along the first direction and along a second direction, which is substantially orthogonal to the first direction, and from disengaging from the seat.
