  • the baling machine may be a self powered unit or may in turn be towed behind a tractor such that, in use, as the baling machine produces bales, the bales are released onto the bale wrapping machine 10 where the bales are wrapped in plastics film and are then deposited on the ground.
  • a front end of the support frame 12 carries a first conveyor belt 18 which is entrained over four rollers 20 which extends widthwise of the support frame 12, one of the rollers 20 being arranged to be driven by an hydraulic motor 22 which is also carried by the support frame 12.
  • a pair of guide arms 24 are provided one at each side of the first conveyor belt 18 to orientate the bale for wrapping.
  • a second conveyor belt 26 is provided at the rear end of the support frame 12, the second conveyor belt 26 being entrained over three rollers 28 each of which extend widthwise of the support frame 12.
  • One of the rollers 28 of the second conveyor belt 26 is driven by an hydraulic motor 30.
  • the wrapping chamber 32 comprises a steel support structure 34 within which is provided a cylindrical wrapping drum 36 supported for rotational movement upon two axial ly spaced sets of four equiangularly spaced wheels 38 rotatably mounted on the support structure 34 and engaging with the outer periphery of the wrapping drum 36.
  • the wrapping drum 36 comprises a pair of parallel steel rings 40 of equal diameter arranged coaxial ly and rigidly separated by means of a plurality of steel spacer bars 42. In order to support the wrapping drum 36 in a stable manner, four of the wheels 38 are arranged to engage with each of the steel rings 40 of the wrapping drum 36.
  • the support structure 34 further carries an hydraulic motor 44 arranged to drive the wrapping drum 36 so as to rotate about its axis.
  • the drive is transmitted to the wrapping drum 36 by means of a drive belt 46 engaging the outer periphery of one of the rings 40.
  • each of the rings 40 Supported at its end by each of the rings 40 is a roll 48 of plastics film and similarly supported, but parallel to the roll 48 is a tensioning roller 50, the plastics film extending over the tensioning roller 50.
  • a cut and hold device 52 is provided at the rear of the wrapping chamber 32, and comprises a blade 54 reciprocable between a lowered position in which it engages with a crimping pad 56 carried by the support frame 12, and a raised position.
  • the bale wrapping machine 10 includes an hydraulic ram 58 arranged to move the blade 54 between its lowered and raised positions.
  • the cut and hold device 52 further comprises an arm 60 which is slidable with respect to the blade 54 and is spring biased towards a position in which it extends below the cutting edge of the blade 54.
  • a support roller 62 is carried by the support frame 12 in the vicinity of the cut and hold device 52 in order to support a wrapped or partially wrapped bale before it reaches the second conveyor 26.
  • plastics film is fed from the supply roll 48, over the tensioning roller 50 and is gripped between the arm 60 and crimping pad 56 of the cut and hold device 52.
  • the hydraulic motors 22, 30, 44 are each connected to the hydraulic output of the tractor towing the baling machine, or any other suitable source.
  • the hydraulic motors 22, 30 used to drive the first and second conveyor belts 18, 26 are operated continuously.
  • the bale On receiving a bale from the baling machine, the bale is carried to the wrapping chamber 32 by the first conveyor 18.
  • a first switch 64 When the front end of the bale reaches the wrapping chamber 32, a first switch 64 is activated thereby initiating operation of the hydraulic motor 44 for driving the drum 36.
  • a third switch 68 is provided in the vicinity of the second switch 66, the third switch 68 overriding the first switch 64 so that whilst a bale extends over the third switch 68, the motor 44 for driving the wrapping drum 36 continues to operate.
  • the third switch 68 is no longer activated and rotation of the wrapping drum 36 stops.
  • a fourth switch 70 is then activated resulting in the lowering of the blade 54 and arm 60 to contact the crimping pad 56. As the arm 60 contacts the crimping pad 56, the plastics film caught therebetween is gripped tightly and the film is then cut by the continued lowering of the blade 54.
  • the bale is carried by the second conveyor 26 until it falls from the rear of the bale wrapping machine 10, the bale wrapping machine 10 then being ready to wrap the next bale, the cut end of the film already being caught between the arm 60 and crimping pad 56 of the cut and hold device 52 in readiness.
  • the bale wrapping machine 10 may include an angled region provided to the rear of the second conveyor 26 in order to control the movement of the wrapped bale to the ground rather than simply letting it fall, thereby reducing the risk of the wrapping splitting on impact with the ground.
  • the tension would be reduced, and then after wrapping for a predetermined length of time, calculated in accordance with the linear speed of movement of the bale and the bale length, the tension would be increased while the length of the bale is being wrapped, and then decreased after a period of time sufficient for wrapping of the trailing end region of the bale to have commenced.
  • the film dispensing arrangement may effect similar control over the speed of rotation of the film supply roll.
  • the efficiency of wrapping of the leading and trailing end faces can be improved by adjusting the angle at which film is supplied to the bale when wrapping the leading and trailing end regions.
  • the tensioning roll or more preferably the whole of the wrapping head, is linked to the rings 40 by extensible linkage arrangements.
  • the extensible linkage arrangements can be mechanically adjustable linkages, or hydraulically extensible devices, and are operated to displace the tensioning roller, or more preferably the whole of the wrapping head assembly, from the normal orientation (parallel to the direction of travel of the bale) when wrapping the leading and trailing end regions.
  • the tensioning roll, or wrapping head will be angled, by means of its linkages such that its end region presented towards the receiving conveyor 26 is disposed closer to the axis of rotation of the drum 36 than the opposite end of the wrapping head or tensioning roller.
  • the wrapping head when the longitudinal extent of the bale is being wrapped the wrapping head will have been moved, relative to the drum 36, such that its axis is parallel to the axis of rotation of the drum and when the bale has moved sufficiently far through the wrapping chamber that it is the trailing end region of the bale which is being wrapped then the angling of the wrapping head or tensioning roll will have been reversed so that the end region of the wrapping head or tensioning roll closest to the input conveyor 18 is closest to the axis of rotation of the drum.
  • Control over the angling of the wrapping head, or the tensioning roller thereof in relation to the region of the bale being wrapped, can be effected in exactly the same manner as described above in relation to the control of the wrapping tension.
  • bale wrapping machine 10 is intended to be towed directly behind a baling machine.
  • the bale wrapping machine 10 may be bolted to or form an integral part of a baling machine.
  • the machine may be towed directly behind a tractor, and used after baling has been completed. In this case, the bale wrapping machine 10 requires a device for loading bales onto the first conveyor 18.
