Abstract: 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.

Abstract: A self-propelled wrapping machine is movable around a product for wrapping the product with a film of synthetic plastic material and includes a self-propalled carriage provided with directional wheels and with a steering assembly for maneuvering the directional wheels. The wrapping machine further includes a spring acting on the steering assembly to exert a first torque and induce the steering assembly (11) to orient the directional wheels according to a prescribed work direction. The wrapping machine also includes a device that is drivable by the steering assembly to exert a further torque, opposite the first torque, on the steering assembly to lighten the assembly and thus facilitate an orienting maneuver of the directional wheels according to a further direction.
