A production method of producing a fiber-reinforced resin molding includes: kneading, in a kneader, molten thermoplastic resin with opened reinforcing fibers obtained by opening a bundle of reinforcing fibers, to produce a kneaded mixture; and placing or charging the kneaded mixture into a molding device to produce a fiber-reinforced resin molding.

A fiber block molding apparatus comprising: —a mold having a lower part and an upper part forming between them a cavity for forming a fiber blank into a fiber block article upon closing the mold; —a conveyor system for receiving the fiber blank to be molded at a receiving position, transporting the fiber blank via a heater for activation of a binding agent, and delivering the heated fiber blank into the lower part of the mold at a delivery end of the conveyor system, and —a horizontal position shifting arrangement for shifting the horizontal position of the delivery end of the conveyor system relative to the lower part of the mold between a first and a second position to lay the fiber blank on the lower part of the mold.

The present invention provides a method for producing a press molded body, wherein a material X that contains a thermoplastic resin Rx and carbon fibers A having a weight average fiber length L.sub.WA and a material Y that contains a thermoplastic resin R.sub.Y and carbon fibers B having a weight average fiber length L.sub.WB are heated, and the heated material X and material Y are pressed within a mold at the same time, thereby producing a press molded body which has a region X that is formed of the material X and a region Y that is formed of the material Y. This method for producing a press molded body is configured such that: Lw.sub.B < Lw.sub.A; Lw.sub.B is from 0.1 mm to 15 mm (inclusive); and the press molded body has a transition zone XY wherein the region X and the region Y overlap with each other.

A die comprises a concave die, a blank holder, and a punch passing through the blank holder. The concave die has a first reference surface, a second reference surface that forms the bottom of a concave shape, and an upright surface connecting the first reference surface and the second reference surface. The blank holder has a blank holder surface that sandwiches a prepreg together with the first reference surface. The punch has a punch surface that sandwiches the prepreg together with the second reference surface, and a punch side face that sandwiches the prepreg together with the upright surface. There is a prescribed relationship between R1, which is the radius of curvature of the corner formed by the second reference surface and the upright surface, and R3, which is the radius of curvature of the corner formed by the punch surface and the punch side face.

A method of making a mesh cushion. The method includes extruding a material through a plurality of filament forming openings in at least one die plate to form a plurality of filaments. The filaments may be at least partially submerged into a fluid to cool and harden the filaments into the mesh cushion.

A method for producing a film having a fine irregular pattern intermittently includes feeding a film to be processed intermittently from upstream side to the vicinity of the surface of a die having a fine irregular pattern, transferring the pattern to the surface of the film by pressing the film against the surface of a die, stripping the processed film on which a pattern is formed from the surface of a die, and then feeding a new film to be processed to the die, wherein the processed film is stripped from the surface of a die by gripping and moving the processed film to the upstream side, and then the processed film is fed by a length of intermittent feed to the surface of a die while preventing the processed film from creasing.
