A wrapping machine for wrapping materials, in particular compacted bales (20) of material such as fodder, loose materials and the like with a strip of wrapping material such as plastics film. It comprises a first wrapping station (2) having wrapping means (94) for applying a strip of wrapping around the bale to partially wrap the bale (20) in wrapping material, a second wrapping station (3) having wrapping means (41, 63) for applying a strip of wrapping material around the bale to completely wrap the bale (20) in wrapping material, and transfer means (50) for transferring the partially wrapped bale (20) from the first wrapping station (2) to the second wrapping station (3). The partial wrapping of the bale prevents its disintegration during transfer. The transfer means (50) is swingable, to transfer the bale (20), through approximately 90 DEG from the first wrapping station (2) to the second wrapping station (3). The first wrapping station (2) includes wrapping means comprising a dispenser (94) for dispensing a strip of plastics film, and means for rotating the dispenser, about a substantially vertical axis, around the bale to partially wrap the bale. The second wrapping station (3) includes means, for rotating the bale about a substantially horizontal axis, and at least one dispenser (4), for dispensing a strip of wrapping material and means for rotating the dispenser (41) around the bale as the bale (20) is turned about the horizontal axis. The invention also includes a compaction station (1) having a compactor (10) for compacting loose material into a bale (20), before wrapping. The compactor (10) comprises a compaction chamber (7), open at both ends, means (87) for directing loose material into the chamber (7), a rotating compaction head (15) including at least one roller (13) rotatable over the loose material within the compaction chamber (7), and capable of moving within the compaction chamber (7) as loose material accumulates within the chamber (7) to compact the material in the chamber (7). Preferably, the compaction chamber (7) is moveable upwardly in a vertical direction as the bale (20) is being formed to expose a part of the partially-formed bale (20), and wrapping means (94) are included to wrap an exposed part of the bale (20) with wrapping material as the compaction chamber (7) is raised.
