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.
