Double cylinder press for formation of fibrous layers

In a double cylinder press for the formation of fibrous layers, comprising a stationary butt and a swing butt which are disposed side by side with the opposed sides thereof opened entirely to communicate with each other and which are provided therein one each with cage cylinders covered at the outer circumferences thereof with wire gauzes and rotatably supported within said stationary butt and said swing butt by means of shafts, said swing butt being capable of being longitudinally swung relative to said stationary butt with a pivot portion formed on the lower portion of the opposed opened sides of said stationary butt and said swing butt as a fulcrum, the edges of said opposed opened sides excluding the uppermost edges of said stationary butt and said swing butt being stretchably joined with each other by means of a flexible member, the improvement wherein:

• each of said stationary butt and said swing butt has its lower portion curved along the arc shape of said cage cylinders,
• said cage cylinders have their respective opposite end portions formed to have a diameter smaller than that of the portions thereof covered with said wire gauzes to define between the adjacent end portions of said cage cylinders compartments for collecting therein masses of fibers formed on the surfaces of said wire gauzes due to a peeling phenomenon, and are provided on the inner circumferences thereof with a plurality of inclined drain plates which are extended in the lengthwise direction of said cage cylinders and disposed at regular intervals, and
• part of said flexible member joining the side edges of said opposed opened sides of said stationary butt and said swing butt assume a U-shape and other part thereof joining the lower edges of said opposed opened sides assume an inverted U-shape.
