An agricultural round baler comprising: - a main frame; - a baling chamber supported by said main frame, said baling chamber having a pair of opposing sidewalls, and a pair of stationary, adjacent rolls (8, 9) which are rotationally affixed to said sidewalls; - means for feeding crop material into said baling chamber for forming therein a cylindrical bale having a cylindrical portion and a pair of opposing ends; and - a bale wrapping mechanism comprising: • a roll holding station provided for holding a roll of wrapping material; • a duckbill provided for clamping one end of the roll of wrapping material, said duckbill being pivotally mounted, via at least a first hinge, to the baling chamber sidewalls, for delivering said wrapping material to said baling chamber by insertion of said duckbill between said adjacent rolls (8, 9) of said baling chamber; and • at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, the axis of said first guiding roll substantially coincides with the axis of said first hinge in such a manner that pivoting said duckbill has no significant influence in the wrapping material distance between the duckbill and the roll holding station, characterized in that said first hinge connects said baling chamber sidewalls with an intermediary arm that is connected to said duckbill so that said duckbill is pivotally mounted to the baling chamber sidewalls via said intermediary arm, and in that the duckbill is pivotally connected to said intermediary arm via a second hinge, whereby the wrapping mechanism comprises a second guiding roll, whereby the axis of said second guiding roll substantially coincides with the axis of said second hinge. - a main frame; - a baling chamber supported by said main frame, said baling chamber having a pair of opposing sidewalls, and a pair of stationary, adjacent rolls (8, 9) which are rotationally affixed to said sidewalls; - means for feeding crop material into said baling chamber for forming therein a cylindrical bale having a cylindrical portion and a pair of opposing ends; and - a bale wrapping mechanism comprising: • a roll holding station provided for holding a roll of wrapping material; • a duckbill provided for clamping one end of the roll of wrapping material, said duckbill being pivotally mounted, via at least a first hinge, to the baling chamber sidewalls, for delivering said wrapping material to said baling chamber by insertion of said duckbill between said adjacent rolls (8, 9) of said baling chamber; and • at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, the axis of said first guiding roll substantially coincides with the axis of said first hinge in such a manner that pivoting said duckbill has no significant influence in the wrapping material distance between the duckbill and the roll holding station, • a roll holding station provided for holding a roll of wrapping material; • a duckbill provided for clamping one end of the roll of wrapping material, said duckbill being pivotally mounted, via at least a first hinge, to the baling chamber sidewalls, for delivering said wrapping material to said baling chamber by insertion of said duckbill between said adjacent rolls (8, 9) of said baling chamber; and • at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, the axis of said first guiding roll substantially coincides with the axis of said first hinge in such a manner that pivoting said duckbill has no significant influence in the wrapping material distance between the duckbill and the roll holding station,
