Abstract:
A wrapping machine for individually wrapping objects, comprising:a delivery conveyor including a plurality of longitudinally arranged stations, each station being adapted to receive one object to be wrapped; means for moving the conveyor stations longitudinally; a film stand for supplying wrapping film longitudinally along the moving delivery conveyor in contact with the objects to be wrapped, the film having longitudinal peripheral edge portions extending laterally and being sufficiently wide to wrap around the objects to be wrapped; a folder mounted on the delivery conveyor and having side arms for folding the film edge portions alongside the objects to partially wrap the objects; a gripping conveyor located adjacent to the delivery conveyor to receive the partially wrapped objects, the gripping conveyor including a plurality of clamping devices spaced apart longitudinally equidistantly with the delivery conveyor stations; means for moving the gripping conveyor and thus the clamping devices longitudinally in synchronization with the delivery conveyor, the clamping devices including opposed gripping fingers; actuation means for causing the gripping fingers adjacent to the delivery conveyor to close to grip the partially wrapped objects through the wrapping film and pull said objects off the delivery conveyor; crimping means located between the clamping devices for crimping closed and cutting off the wrapping film between the wrapped objects; and said actuation means including means for opening the gripping fingers to release the wrapped objects.
