    摘要： A METHOD OF MAKING A FORAMINOUS FORMING CONVEYOR FROM TEXTILE SHEET MATERIAL HAVING A LACE-LIKE DESIGN BY TREATING SUCH MATERIAL SO AS TO PROVIDE A DIMENSIONALLY STABLE CONVEYOR HAVING FLEXIBILITY SUFFICIENT TO ALLOW IT TO TRAVEL IN STRAIGHT AND CURVED PATHS AND FURTHER HAVING A FLAT FORMING SURFACE FOR RECEIVING DEPOSITED SOLIDIFIABLE MATERIAL; SUCH DEPOSITED MATERIAL, AFTER SOLIDIFICATION, BEING EASILY STRIPPED FROM THE FORMING SURFACE IN A CONTINUOUS AND EFFECTIVE MANNER.

    摘要： A continuous method and apparatus for forming foraminous sheet film having elastomeric properties and for composite materials including such film is disclosed. The method generally includes the steps of driving successive portions of a continuous foraminous conveyor in a substantially cylindrical path depositing a material in particularized form which material in dry form possesses elastomeric properties onto and about the inner surface of such cylindrical path; drying such material into a foraminous sheet film and removing said film from said conveyor. The process also may include the adherence of either one or two plies of material to the film. The apparatus includes a deposition arrangement including means to deliver a flowable material which in dry form possesses elastomeric properties to a foraminous conveyor to provide a continuous foraminous film having elastomeric properties. The preferable deposition apparatus includes a centrifugal dishlike member adapted to deliver the flowable material in particularized form onto the foraminous forming surface.

    摘要： APPARATUS AND METHOD ARE DISCLOSED FOR THE CONTINUOUS FORMATION OF FORAMINOUS ELASTOMERIC SHEET MATERIAL FROM A COAGULABLE LIQUID, SUCH AS A LATEX. THE COAGULABLE LIQUID IS DEPOSITED ON A FORMING MEANS SHOWN PROVIDED ABOUT THE FACE OF A ROTATABLE CYLINDER, OR ALTERNATIVELY ALONG AN ENDLESS CONVEYOR BELT. THE LIQUID RECEIVING SURFACE OF THE FORMING MEANS INCLUDES A SPACE SEPARATED PLURALITY OF PROJECTIONS. THE REGIONS BETWEEN THESE PROJECTIONS PROVIDE OPEN FACED LOCATIONS FOR THE RECEPTION OF THE COAGULABLE LIQUID. A MEANS FOR DEPOSITING THE LIQUID AS A LAYER ON THE FORMING SURFACE IS PROVIDED. THIS DEPOSITING MEANS INCLUDES A SPREADING MEANS AT ITS EXIT WHICH ESTABLISHES THE TOP SURFACE OF THE LIQUID. AN ACTIVE GELLING OR COAGULATING AGENT IS APPLIED TO THE LIQUID LAYER IMMEDIATELY EMERGING FROM UNDER THE SPREADING MEANS TO PREVENT THE FORMATION OF A GELLED OR COAGULATED FILM OVER THE PROJECTION TOP SURFACES, AND FORM A HOLE IN THE DEPOSITED LAYER AT EACH PROJECTION LOCATION. IN THE DISCLOSED EMBODIMENTS THE SPREADING MEANS IS PROVIDED BY A FLEXIBLE BLADE MEMBER WHICH WIPES ALONG THE TOPS OF THE PROJECTIONS. THE SURFACE COAGULANT ALSO SERVES TO PREVENT THE BUILD-UP OF A COAGULUM ALONG THE BLADE SPREADING REGION. THE LIQUID IS COAGULATED AND STRIPPED FROM THE FORMING SURFACE AS SHEET MATERIAL. IN ORDER TO REDUCE THE COAGULATION TIME, A HEAT-SENSITIVE COAGULABLE LIQUID MAY BE USED, WITH APPROPRIATE HEAT BEING APPLIED TO THE FORMING SURFACE.
