A large round baler is equipped with a device for wrapping bales with a web of net wrapping material. The device includes structure for supporting a spare supp ly roll of wrapping material a short distance vertically above a zone for containing an active supply roll of wrapping material. The structure for supporting the spare roll is selectively movable to a non-use position for permitting a pressure-applying roller, that normally engages the active supply roll of wrapping material, to be swung vertically out of the way so a s to permit the spare supply roll to be moved into place as the active supply roll once the latter is depleted. A pair of retractable loading supports are provided for supporting the spare supply roll at a location reawardly of the zone prior to moving the spare roll into the zone to take the place of the depleted active supply roll. A net guide roll has one end mounted for being selectively lifted to permit easier threading of a length of net that has been pulled fr om the spare supply roll when the latter is located on the loading supports.
