Abstract: In a twine wrapping apparatus for a crop roll forming machine effective to bind the periphery of a crop roll with a binding material having at least a first binding material dispenser and a second binding material dispenser, drive apparatus connected to the binding material dispensers and overload protective apparatus positionable between a driving connection and a non-driving connection between the drive apparatus and the binding material dispensers, there is provided an alignment apparatus cooperable with the drive apparatus and the overload protective apparatus to retain the drive apparatus so that it is held in a fixed position while the overload protective apparatus is moved from the non-driving connection to the driving connection to thereby permit the binding material dispensers to be driven through their predetermined paths of travel.
