Suspension arrangement for a roll

Abstract

A vibration-minimizing suspension mechanism for a press roll is provided. The press roll and an opposing roll each having a rotational axis and cooperate to form a press nip adapted to impart a linear load on a fiber web passing therethrough. The linear load is oriented through the rotational axes of the press roll and the opposing roll. As such, the suspension mechanism comprises a suspension arm having opposed ends and a medially-disposed pivot, wherein the press roll is rotatably engaged at the rotational axis thereof with one of the opposed ends of the suspension arm. The suspension arm is further 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.
