<p>An elongate soaking basin has a screen mounted on a movable frame. The screen is vertically movable into and out of the soaking basin. The soaking basin has a compression wheel feeding pieces of lumber transversely into the soaking basin against the screen. The pieces of lumber are compressed between the screen and the compression wheel. The screen is pivotally supported between two limit positions in the movable frame and when the screen is forced against one of the limit positions, the frame is moved to reposition the screen, thus keeping the pieces of lumber aligned and under the proper compression.</p> |
