Abstract
A press roll device for applying pressure on a piece of wood moving along a path. The device has a frame mounted in proximity to the path of the piece of wood and a lower and an upper arm both pivotally connected to the frame. A roller is rotationally mounted on the end of the lower arm and a jack is resiliently connected to the corresponding end of the upper arm. A bag of compressed air is disposed between the ends of the lower and upper arm, resiliently separating the roller and the jack. In this manner, the bag of compressed air absorbs the vibration of the roller caused by unevenness in the piece of wood, at least partially.

A press roll device for applying pressure on a piece of wood moving along a path, the device comprising:
- a frame mounted in proximity to the path of the piece of wood;
- a lower arm having a first end and a second end, the first end being pivotally connected to the frame;
- a roller for applying pressure on the piece of wood as said piece of wood moves along the path, the roller being rotationally mounted on the second end of the lower arm;
- an upper arm having a first end and a second end, the first end of the upper arm being pivotally connected to the frame, and the second end of the upper arm extending in proximity to and above the second end of the lower arm;
- a bag filled with compressed air disposed between the second ends of the lower and upper arms;
- and
- a jack connected to the second end of the upper arm, for applying a pressure on the piece of wood via the second end of the upper arm, the bag, the second end of the lower arm and the roller.
