 Image Number 3 for United States Patent #3937614.
A press for compressing a liquid-bearing absorbent article to transfer a portion of the liquid materials to a contiguous article has two concentric pressure feet. One is an outer foot member that bears against the liquid-bearing article along the periphery of the pressure area, and the other is an inner, deformable and contoured foot member that applies pressure to the liquid-bearing article progressively along the pressure area. A photometer can be combined with the press to measure constituents or other properties of the liquid materials being transferred.
