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.
