The present invention relates to a method of applying a film to a body. In this respect, a film is first applied to and positioned at a transfer mold and the body to be film coated is introduced into the transfer mold to which the film to be attached is applied or the transfer mold to which the film to be attached is applied is introduced into the body to be film coated so that the film is located between the body and the transfer mold. In the further course, a vacuum is applied in a region between the body and the film and/or an excess pressure is applied in a region between the transfer mold and the film so that the film moves from the transfer mold onto the body. A particularly simple method that is fast to be carried out is thereby provided for applying a film to a surface.

Resin-molded articles, to which such advantages as strength, rigidness and light weight are secured thanks to kneading with fibers, and which has excellent surface characteristics such as smoothness of the surface and beauty in the appearance, and resistance against weather, ultraviolet rays and light are provided.

The resin-molded article 10 is structured by sticking a resin surface skin member 3 provided with an adhering layer 2 to a molded fibrous base member 1 comprising any of carbon fibers, glass fibers and the complex thereof, and the resin-molded article is manufactured according to the following steps, specifically a step of placing a molded member comprising mixture of fibers and resin on a tray 23, a step to arrange a resin surface skin member provided with an adhering layer onto the molded member such that the adhering layer of the resin surface skin member is directed downward, a step to render the surroundings of the molded member and the resin surface skin member in a negatively-pressurized condition and to concurrently heat the resin surface skin member to raise the tray so that the molded member is closely contacted to the softened resin surface skin member, a step to render the upper part of the tray in a pressurized condition, a step to release the pressure applied to surrounding of the tray and a step to remove the molded base covered with the resin surface skin member.

A molding die device is provided for bringing a resin sheet into close contact with a pair of dies by vacuum suction from a cavity surface to perform molding. An outer frame portion is formed integrally with an outer peripheral portion of the respective dies arranged to face each other. Moreover, one of the dies has a recessed portion formed at the position of the one of the dies facing the outer frame portion of the other die and configured so that the outer frame portion of the one of the dies can be housed in the recessed portion. The outer frame portion is formed to protrude most in each die. Upon molding, the dies are clamped together after vacuum suction has been performed with the resin sheet being arranged in contact with the outer frame portions.

Disclosed is a method for producing an automobile sound absorbing member through molding. In the method, a first fiber and a second fiber are bonded to each other and molded at the same time, so that a working process and a process cycle are simplified, thereby improving production speed and reducing investment for equipment and facility. The method includes (a) preparing a first fiber and a second fiber, (b) providing an adhesive member between the first fiber and the second fiber and placing an aggregate of the first fiber, adhesive member, and the second fiber in a molding machine, and (c) pressing an upper mold and a lower mold of the molding machine so that the first fiber and the second fiber are bonded and molded into a molded body.
