A cylindrical bale-wrapping apparatus is provided having a single, rotatable bale-wrapping ring and a ram feed device for feeding unwrapped bales through such bale-wrapping ring, and, after its initial wrapping operation, into contact with a previously wrapped bale. The apparatus has a valve operated by the weight of a bale to move the bale on a feeding stroke through the bale-wrapping ring and by a valve, when the bale is at a bale-wrapping station, to rotate the bale-wrapping ring for bale-wrapping. The ram feed device also assists in moving the wrapped bale from the rear of the apparatus. The apparatus is of simple structure with a single hoop for the wrapping ring which is provided with rotation supports. A cantilever support extends longitudinally from a portion of the hoop to carry the wrap material dispenser and tensioner.

A method of wrapping a bale in a bale-wrapping apparatus which includes a forward end portion including front wheels and a loading zone, a rear end portion including rear wheels and a bale-wrapping station disposed intermediate said forward end portion and said rear end portion, a single rotatable bale-wrapping ring located at said bale-wrapping station, said bale-wrapping ring extending around a longitudinally-extending pass line for said bales, a bale wrap material dispenser and a tensioner for tensioning said bale wrap material as it is being unrolled from said dispenser, a mounting for said bale wrap material dispenser and tensioner, said mounting being carried by, and being rotatable with, said bale-wrapping ring, a ram feed device at said forward end portion of said apparatus means on said ram feed device to actuate an on/off switch, said ram feed device being actuatable to be reciprocally-moveable intermittently between a forward position and a rearward limit position in bale feeding strokes for urging unwrapped bales in succession longitudinally along said pass line, and through said bale-wrapping ring, a conveyor at said rear end portion for directing wrapped bales from said bale-wrapping ring, and cooperative means for moving the apparatus forwardly, said method comprising: (i) detecting an unwrapped bale at said loading zone and as a consequence actuating said ram feed device in a bale feeding stroke to urge said unwrapped bale longitudinally and rearwardly along said pass line towards said bale-wrapping station; (ii) actuating an said “on/off”switch to the “on”position when said ram feed device in its bale feeding strokes and said actuating means thereon pass a first region, thereby causing rotation of said bale-wrapping ring to cause bale wrap material to be wrapped around a bale at said bale-wrapping station; (iii) automatically initiating a ram return stroke to return said ram feed device forwardly to its forward position when said ram feed device abuts a stop detecting means at its rearward limit position; and (iv) actuating said “on/off”switch to the “off”position when said ram feed device and said actuating means thereon pass said first region in its ram return stroke to stop rotation of said bale-wrapping ring.
