Abstract: An assemblage for bonding the skin of an airfoil to the core of the airfoil includes a hybrid caul plate assembly for covering the surface of the airfoil assembly which is exposed to bonding pressure. The hybrid caul plate includes a central elastomeric component and peripheral semi-rigid metal components. The semi-rigid metal components are formed from a steel sinusoidal mesh and are axially elongated. The mesh is flexible in the direction of elongation, but are rigid in the transverse direction. The peripheral semi-rigid caul componnents will thus closely conform to the contours of the core in the axial direction, and will, at the same time, provide support for the edges of the core so that the core edges will not be crushed or deformed by bonding pressure applied to the assemblage during the skin-to-core bonding process. The result of using the hybrid caul plate assembly is an improved skin-to-core bond wherein bridging or voids in the bond line at the periphery of the airfoil are avoided.

Abstract: In a method and device for molding a laminated molded assembly by simultaneously forming a resin core member and integrally joining a surface skin member in a die assembly for mold press forming comprising an upper die and a lower die, the moldability of the surface skin member is improved by softening the surface skin member by blowing hot air against the surface skin member from air holes provided in the upper die which is associated with the surface skin member.

Therefore, distortion of the decoration sheet, appearance of wrinkles, and breakage thereof become little. Next, the female die and the male die are coupled with each other to effect die clamping, and a molten resin is poured to fill the molding cavity to effect injection molding.

Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.
