  • Publication number: 20070187856
    Abstract: A multi-layered blown film forming apparatus contains an adapter provided to supply a multiple types of resins, a forming die provided on a downstream side in an axial direction of the adapter, and a temperature controller mechanism. Molten resins of multiple types are individually fed to the forming die through the adapter. The forming die contains a main body, a multi-layer structure of a plurality of single-layer thin film dies disposed in an inner portion of the main body in an axial direction to produce a plurality of resin thin films corresponding to the molten resins of the multiple types, and a first annular path formed between main body and the multi-layer structure. A multi-layered thin film in which the plurality of resin thin films are overlaid is passed through the first annular path and is outputted as a multi-layered thin annular film. The temperature controller mechanism controls individual temperatures of the plurality of single-layer thin film forming dies independently.

  • Patent number: 6273704
    Abstract: The present invention relates to a casting apparatus for formation of a resin-made membrane which is made to be capable of accomplishing a stable pressure reduction through a suction chamber irrespective of the dimension of an interval between a die and a cooling roll. Thus, in the apparatus according to this invention, a suction chamber is disposed independently of a die and is located to define a necessary seal gap with respect to a cooling roll. Further, a circumferentially moving mechanism is provided to shift the suction chamber along the circumferential directions of the cooling roll while maintaining the necessary seal gap. This invention is applicable, for example, to a biaxial oriented film machine, a non-oriented film machine, a sheet machine, and others.
