Abstract
A twine tension relief assembly for a baler including a tension detection apparatus for detecting the tension in a line of twine, a biased cutting element displaceable between a first retained position and a second released position and an actuator adapted to cause the biased cutting element to move from the first retained position to the second released position in response to a signal issued by the tension detection apparatus. The practical application includes when the tension in a strand of twine exceeds a predetermined threshold, the tension detection apparatus causes movement of the biased cutting element so that a strand of twine passing though the twine tension relief assembly is severed and damage to the knotter mechanism and its component parts is avoided.
