ABSTRACT:
A wrapping mechanism for use in combination with a round baling machine is disclosed wherein the baling machine has a frame, a baling chamber, and arms for supporting the roll of flexible material. An electric motor is provided on a shaft upon which the flexible material is mounted for selectively imparting rotational motion to the roll. The shaft is provided with an overriding clutch. A pulley is provided on the shaft for the roll. A belt extends around the pulley and is secured by its ends to a spring which in turn is secured to the frame of the machine to provide a drag for the shaft and the roll.
A plate means is mounted on the frame adjacent the roll to separate a layer of material as it departs from the roll. The layer of material is directed towards the baling chamber or compartment.
A wind shield plate is mounted on the frame adjacent the separated layer of material to protect the material from drafts. A cutter bar is mounted adjacent the entrance to the baling compartment. Spring means maintain the cutter bar in an inoperative position. The cutter bar may then be manually tilted to cause it to move against the layer of material to sever the same.
The method of this invention involves forming a round bale in the baling compartment of the baling machine, and then providing a roll of plastic material on the baling machine with an initial rotational surge to cause a layer of plastic material to emerge from the roll towards the baling compartment. The baling machine is then actuated to cause additional material to be baled to engage the layer of plastic material and to move the layer of plastic material into fixed contact with the bale. The bale is then rotated within the machine to cause the bale to pull additional material from the roll and to wrap the material around the periphery of the bale. The material then is cut between the bale and the roll of material. Rotational resistance is provided to the roll of plastic material to prevent it from free wheeling while the layer of material is being separated therefrom. The leading edge of the layer of material is shielded from wind currents.
