  • Patent number: 4522120
    Abstract: The length of a bale is normally gauged by a fixed toothed wheel engaging the top of the bale. Therefore the height of the bale can effect the cut-off point so that bales can be of uneven length. This device utilizes a floating gauge wheel or star wheel which therefore rotates at a constant speed so that its actuation point is constant. It is connected to the knotting device which in turn controls the cut-off point of the bale being formed.

  • Patent number: 4516492
    Abstract: A bale discharge chute normally is provided with a pair of spaced and parallel sides, a lower member and a movable upper pressure plate having links connecting the distal ends. The present invention includes a transverse anchor member for the upper connection of the links together with an adjustable compression spring reacting between the member and the pressure plate thus giving superior pressure plate control and preventing damage from occurring to the structure due to excessive tension yet at the time will permit upward movement of the pressure plate if a predetermined pressure is exceeded.
