The apparatus is for forming a resin film from a resin for a middle portion to form a resin film main body of the resin film and a resin for edge portions to form both side edge portions in a crosswise direction of the resin film. The apparatus comprises: a feed block which includes a joining part where the resin for the middle portion in a molten state and the resin for the edge portions in a molten state are joined in such a manner as to enclose both side edges in the crosswise direction of the resin film main body with the resin for the edge portions; and an extruding die through which the joined resins are extruded to form the resin film. Thus, a method and apparatus for forming the resin film can avoid the inclusion of the resin for the middle portion in the trimmed-off selvages while preventing the film separation of the resins for the middle portion and for the edge portions, and therefore, increase the recyclability and the productivity of the resin film.

In the resin film forming method for extruding a fused resin from an extruder die to form a resin film, the second resin forming both ends in width direction of the resin film uses a resin greater in extension viscosity than the first resin forming the center in width direction of the resin film. Thereby, even if production conditions such as resin condition and operating conditions change, faults such as neck-in and its resultant thickening at both ends of the resin film can be suppressed. In the production of a laminate by nipping a support and a resin film of a thermoplastic resin by means of a nip roller and a cooling roller while coating the resin film onto the surface of the support, the accompanying air following the rotation of the cooling roller to the nip point is shut off by blowing a gas permeable through the resin film from a gas jet nozzle toward the surface of the cooling roller. Thereby, the occurrence of craters can be inhibited, a laminate excellent in surface appearance can be produced and the production of a laminate effective especially at the time of a line speed rise in the laminate production is performable.

The present invention provides a method of producing a pattern member at high productivity and low cost. In the method of the present invention, inks of plural colors are applied on a substrate and dried to produce several kinds of single color films having color ink layers of plural colors formed on the surface, then, the single color film of R color is overlapped on the substrate, and the overlapped substrate and single color film are pressed by a pressing member having a convex portion of given pattern formed on the surface, to transfer parts corresponding to the pattern of the convex portion of the color ink layer to the substrate. The above-described operation is repeated at frequency corresponding to plural colors to form a multi-color pattern composed of color ink layers of plural colors of given pattern on the substrate.

Rollers, substrates, products and the like are not smeared with a sticky volatile component when a gas is blown from a blower provided near an extruding die to produce laminates. The blower is heated by a heater at a temperature not below the volatilization temperature of the volatile component volatilized from a resin film of thermoplastic resin extruded in molten conditions from the extruding die, and therefore the volatile component cannot stick on the blower and is immediately volatilized on the blower.

In the method for manufacturing pattern members, a plurality of different kinds of materials are formed into the respective patterns on a web. In the method, a material transfer sheet on which a material layer for a pattern member has been formed is made in close proximity to the web and to run in such a direction as to intersect the direction of the web running, while allowing the web to run, and at the points where the web and the material transfer sheet intersect, the material layer for the pattern member is transferred from the material transfer sheet to the web with a transferring device so that it is formed into a pattern. Thus, both productivity and product quality are improved in the manufacturing of pattern members.

The manufacturing apparatus of a resin molded product has a feed block that sets a layer configuration of the resin molded product obtained by molding a plurality of molten resins. The feed block includes a feed block body having a through hole, and a plurality of replacement blocks that are removably fitted into the through hole and have layer configuring passages corresponding to different layer configurations. A replacement block before change is pushed out of the through hole by a replacement block having a layer configuring passage corresponding to a layer configuration after change, thereby changing the layer configuration. This allows an easy change of a layer configuration, and in particular, prevents degradation of resin due to heat or oxidation, and reduces time for the change and a material loss even when a significant change of the layer configuration such as a change of a layer arrangement is performed.
