    • PROBLEM TO BE SOLVED: To solve the problem of a usual method of joining a pressurized film 2 to a fitting frame 3 over the whole part overlapping therewith, that the film 2 is apt to be torn off when it is pressed on an upper plate 20, since the film 2 is subjected not only to a tensile force in the radial direction of the surface thereof at the opening end face of the fitting frame 3 in particular, but also to the tensile force in the direction of the thickness of the film 2. SOLUTION: The pressurized film 2 is not joined to the fitting frame 3 in the vicinity of the opening end face 13 of the fitting frame 3. Besides, the opening end face 14 of a frame 6 is formed inward from the opening end face 13 of the fitting frame 3 at a distance three times or larger than the dimension of the film thickness of the film 2. Moreover, a stepped part 26 is provided at the outer peripheral end of the pressurized film 2 and the film 2 is joined to the fitting frame 3 on the whole surface of the stepped part so that the opening end face 13 of the fitting frame 3 comes into contact with the stepped part 26.

    • PROBLEM TO BE SOLVED: To provide equipment for forming which eases the friction between the surface of a pressing tool and the surface of a forming material such as a paper sheet on the occasion of press forming and makes creases hardly formed even in a place where the amount of change of shape is large and which is automated, by using the pressing tool which is expanded by a fluid supplied and has flexibility or elasticity, for one tool out of a male force and a female mold. SOLUTION: The equipment (A) for forming has a conveyor device (3) having a conveying chain (34), base forms (4) provided for the conveying chain (34) and a pressing tool device (5) forming a formed article in cooperation with the base forms (4). The pressing tool device (5) is equipped with the pressing tool (56) formed of a sheet which is expanded and contracted by introduction and discharge of a fluid and has flexibility, a hydraulic cylinder (S2) moving the pressing tool (56) up and down, a fluid pump (58) introducing the fluid into the pressing tool (56) and discharging it therefrom and an electric heater heating the pressing tool (56) indirectly. The forming material is pressed against the base form (4) by the surface pressure of the pressing tool (56) and thereby it is formed.
