A winding device (1,10,100,1000) for loads, comprising a reel-holder roll (2) destined for receiving a reel of an extensible plastic film and comprising a vertical column (3). According to the invention the roll (2) is movable along the column (3); the device (1,10) comprises a lifting plane (4) suitable for receiving a load movable along the column (2), so that said device (1,10) can be used as both winder and lifter for forming the load.
摘要:
A bale wrapping mechanism has a roll holding station and 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 adjacent rolls of said baling chamber, wherein the wrapping mechanism further has at least a first guiding roll for guiding the wrapping material between said roll holding station and said duckbill, wherein said first guiding roll axis substantially coincides with the first hinge axis.
