Abstract:
A vibration-minimizing suspension mechanism for a press roll, the press roll forming a press nip with only an opposing roll, each of the rolls having a rotational axis, the press nip being adapted to impart a linear load on a fiber web passing therethrough, the linear load being oriented through the rotational axes of the press roll and the opposing roll, said suspension mechanism comprising:a suspension arm having opposed ends and a medially-disposed pivot, the press roll being rotatably engaged at the rotational axis thereof with one of the opposed ends of the suspension arm, the other of the opposed ends of the suspension arm being configured to have a force applied thereon so as to provide the linear load at the press nip about the pivot, the suspension arm further being pivotably and adjustably mounted at the pivot so as to allow the pivot to be adjusted in substantially parallel relation to the linear load, the adjustability of the pivot thereby allowing a mounting line along the suspension arm, the mounting line being defined by the pivot and the rotational axis of the press roll, to be maintained in substantially perpendicular orientation to the linear load to thereby minimize vibration in the press roll.
