An apparatus for facilitating the replacement of an endless press felt in a paper and board making machine includes an actuator for lifting a roll which is in contact with a press felt. The actuator operates to lower a roll holder carrying the second end of a roll. The apparatus also includes a roll support mounted on a section between roll ends and, through the intermediary of a lever, is pivotably linked to a fixed fulcrum on a base structure. The roll support is linked by means of a chain serving as a connecting member to the second end of the roll. |
