Open the CIPO recordAbstract From the Canadian patent
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.
