Abstract:
A tensioning mechanism for minimizing tension variations in a moveable endless belt having a desired tension setting, the tensioning mechanism comprising:(a) a moveable member for mounting transversely to a direction of movement of the moveable endless belt and into contact with the moveable endless belt;(b) a first assembly including a first rotatable arm having a first end connected to said moveable member, and a second end coupled to a first pivot; and(c) a second assembly including a tensioning force applying means, and a second rotatable arm having a first end connected to said moveable member and a second end coupled to a second pivot, said second rotatable arm forming a lap angle with said first rotatable arm, and said tensioning force applying means applying a tensioning force to said moveable member having a force direction that is non-orthogonal relative to the direction of movement of the moveable endless belt, thereby tensioning the moveable endless belt and minimizing variations from the desired tension setting of the moveable endless belt.
