Abstract

A wrapping arrangement for an agricultural round baler includes a support frame and a wrapping mechanism including at least one wrap material feeder mounted on the support frame. The wrap material feeder includes a supply of wrap material. At least one wrap material clamp and cutting device is operably mounted to the wrap material feeder, and a clamp mechanism is mounted proximate to the wrap material clamp and cutting device. The clamp mechanism is adapted to clamp a free end of the wrap material by a biasing clamping force for pre-positioning the wrap material for functional operation with the wrapping mechanism.

First claim

The invention claimed is:

1. A wrapping arrangement for an agricultural round baler, comprising:
a support frame having a frame member;
a wrapping mechanism including at least one wrap material feeding means mounted on the support frame, the at least one wrap material feeding means including a supply of wrap material;
at least one wrap material clamp and cutting device operably mounted to the at least one wrap material feeding means; and
a clamp mechanism mounted proximate to the at least one wrap material clamp and cutting device, the clamp mechanism including a profiled resilient element mounted on the frame member and moveable between an operative clamping configuration and an operative de-clamping configuration, and a stationary element positioned against the profiled resilient element when the profiled resilient element is disposed in the operative clamping configuration for engaging the wrap material directly between the stationary element and the profiled resilient element in clamping engagement, wherein the profiled resilient element is elastically displaceable between the operative clamping configuration and the operative de-clamping configuration to apply a biasing clamping force against the stationary element for pre-positioning the wrap material for functional operation with the wrapping mechanism.

2. The wrapping arrangement of claim 1 , wherein the stationary element is integrally formed on the frame member of the wrapping mechanism.

3. The wrapping arrangement of claim 1 , wherein, in the operative clamping configuration, the profiled resilient element applies a clamping force against the stationary element.

4. The wrapping arrangement of claim 1 , wherein, in the operative de-clamping configuration, the profiled resilient element is displaced away from the stationary element thereby relieving the clamping force.

5. The wrapping arrangement of claim 1 , wherein the profiled resilient element is displaceable from the operative clamping configuration to the operative de-clamping configuration by applying a displacement force, where the displacement force generates elastic energy in the profiled resilient element.

6. The wrapping arrangement of claim 1 , wherein an initial free end of the wrap material remains clamped to the clamp mechanism.

7. An agricultural round baler, comprising:
a support frame having a frame member;
a baling chamber supported by the support frame;
a wrapping mechanism including at least one wrap material feeding means mounted on the support frame, the at least one wrap material feeding means including a supply of wrap material;
at least one wrap material clamp and cutting device operably mounted to the at least one wrap material feeding means; and
a clamp mechanism mounted proximate to the at least one wrap material clamp and cutting device, the clamp mechanism including a profiled resilient element mounted on the frame member and moveable between an operative clamping configuration and an operative de-clamping configuration, and a stationary element positioned against the profiled resilient element when the profiled resilient element is disposed in the operative clamping configuration for engaging the wrap material directly between the stationary element and the profiled resilient element in clamping engagement, wherein the profiled resilient element is elastically displaceable between the operative clamping configuration and the operative de-clamping configuration to apply a biasing clamping force against the stationary element for pre-positioning the wrap material for functional operation with the wrapping mechanism.

8. The agricultural round baler of claim 7 , wherein the stationary element is integrally formed on the frame member of the wrapping mechanism.

9. The agricultural round baler of claim 7 , wherein, in the operative clamping configuration, the profiled resilient element applies a clamping force against the stationary element.

10. The agricultural round baler of claim 7 , wherein, in the operative de-clamping configuration, the profiled resilient element is displaced away from the stationary element thereby relieving the clamping force.

11. The agricultural round baler of claim 7 , wherein the profiled resilient element is displaceable from the operative clamping configuration to the operative de-clamping configuration by applying a displacement force, where the displacement force generates elastic energy in the profiled resilient element.

12. The agricultural round baler of claim 7 , wherein an initial free end of the wrap material remains clamped to the clamp mechanism.
