ABSTRACT:
A wrapping means tensioning device is provided for a round baler and comprises an idler assembly and an application assembly. Wrapping means, like net, when drawn during a wrapping cycle acts onto the idler assembly, which in turn will press an application element of the application assembly against a roll, on which wrapping means is stored. This provides for proper tension during a wrapping cycle without the need for springs or the like, the force of which would need to be overcome, when a wrapping device is brought into a non-operative loading mode.
