Wrapping device

1. A wrapping device for at least one of enveloping and packing agricultural crop bales, the wrapping device comprising:

a wrapping floor for receiving and rotating a pressed crop bale, and

a guide frame for two wrapping material carriers for enveloping the bale situated on the wrapping floor with wrapping material in the form of webs, wherein the guide frame is height adjustable and pivotable about a horizontal axle which runs parallel to the axis of rotation of the crop bale, in order to set the center of the wrapping material approximately at the location of the center of the crop bale to be wrapped; and

wherein the guide frame is configured to be height-displaceable in a straight line in a vertical direction and at right angles to the wrapping floor is fixable at different distances to the wrapping floor.

2. The wrapping device of claim 1 , wherein the axle is arranged approximately at the location of the center of the wrapping material for a medium-sized crop bale which is situated on the wrapping floor.

3. The wrapping device of claim 1 , wherein the guide frame is configured to be set to different angles of inclination with respect to the wrapping floor.

4. The wrapping device of claim 1 , wherein actual diameters of the crop bales determined in a round bale press which is suitable for pressing differently sized bales are used as parameters for the adjustment of the guide frame.

5. The wrapping device of claim 1 , wherein the guide frame is adjustable by an adjusting device, depending on at least one of: a diameter of the crop bale and a width of the wrapping material.

6. The wrapping device according to claim 5 , wherein a control device is directly or indirectly operatively connected to a sensor that determines the bale diameter, and to a sensor that determines a width of the wrapping material.

7. The wrapping device according to claim 6 , wherein the control device is operatively connected to a second sensor that determines the position of the guide frame.

8. The wrapping device according to claim 1 , wherein an adjusting device for pivoting the guide frame is configured as at least one of: an electrical, pneumatic, and hydraulic linear motor.

9. The wrapping device according to claim 1 , wherein the guide frame with the wrapping material carrier is rotatable by a motor, or that at least one wrapping material carrier is mounted in or on the guide frame so as to be displaceable by the motor.

10. The wrapping device according to claim 1 , wherein the wrapping floor is arranged downstream of a bale press, wherein the guide frame is adjustable about a rotary shaft which is arranged on the end situated near the bale press.

11. The wrapping device according claim 1 , wherein the guide frame is movably placed around the bale forming chamber of a bale press and encloses the latter, wherein the bale forming chamber floor or a part thereof is configured as the wrapping floor.

12. The wrapping device according to claim 1 , wherein the guide frame is fixed in the wrapping position, so that it is kept at a constant distance with respect to the wrapping floor, while, in a transport position, the guide frame is movable about its rotary shaft, wherein the movement is limited by at least one of: a spring and damping mechanism.

13. The wrapping device according to claim 1 , wherein the guide frame comprises a ring or at least one pivot arm.
