ABSTRACT:
As the twine dispensing tube swingably approaches its home or standby position, the tube strikes one leg of an L-shaped, pivoting lever of the cutter to swing the opposite leg thereof up into edgewise engagement with the underside of the twine such that the latter is stretched between the raised leg and the end of the tube. A depending, swingable knife of the cutter which has been momentarily pushed by the tube out of its path of travel returns with its sharp edge engaging the twine stretch and depresses the latter out of a straight-line relationship between the tube and the raised leg of the lever such that, as the tension and stress in the moving twine stretch increase due to its deflected, serpentine condition around said knife edge and the lever and the opposite pulling forces exerted by the tube and the bale, the twine severs itself against the sharp edge of the knife.
