Abstract: Apparatus for wrapping an article 14, e.g. a silage bale, in a film 4 (e.g. a plastics film) comprises a pair of stretch rollers 8 and 12 for stretching the film 4, a dispenser 2 for delivering the film to the rollers and means for rotating the article e.g. a turntable, to take up film 10 from the rollers, wherein the means for rotating the article comprises a first hydraulic motor (20, Fig. 2) and the stretch rollers are driven by a second hydraulic motor (22, Fig. 2) connected in series to the first motor to run on the exhaust there from the ratio of, the output of the motors being fixed. Roller 12 runs faster (e.g. 55% 70% faster) then roller 8 to stretch the film. One of the stretch rollers constitutes the first of two nipped rollers 6 and 8, the second 6 being directly driven by the second motor and geared to the first nipped roller to drive it at the same peripheral velocity. The nipped rollers act to isolate dispenser 2 from fluctuations in film tension. A biassed jockey may be included to maintain the tension in the film between roller 12 and article 14. A flow control valve 24 regulates the coupling between the motors by diverting some of the exhaust oil from motor 20. Other valves may be incorporated as safety features or to allow reversal of the turntable. <IMAGE>
