For continuous production of a resin film having a plain surface, a resin solution cast in film form over an endless belt is pre-hardened by a gas stream supplied for flow in a direction generally parallel to the surface of the endless belt, and then a jet of gas is blown in the direction of movement of the endless belt whereby the resin is hardened. In the process for resin film production wherein the resin film is cast over the endless belt and then pre-hardened by a parallel gas stream, the cast film being then hardened by a jet of gas, the installation for production is divided by partitions so as to enable various stages to be operated independently.

Method and apparatus for continuously producing resin films and

An end portion-treating method and apparatus for manufacturing a synthetic resin film by first extruding through a slit die or coating with the use of a coater onto or on a conveyor belt or drum a fluid synthetic resin composition in a smooth layer form, and then solidifying it. Gas is blown at both end portions of the film of the fluid synthetic resin composition extruded onto the surface of the conveyor belt or drum to change the sectional form of both end portions. A synthetic resin film is obtained without creasing in the process of drying or cooling of the film or lifting of the film off the surface of the conveyor belt. A film of superior quality is thus provided. Also, since both longitudinal end portions of the film need not be trimmed off and discarded, the film manufacturing effifiency is improved, and the manufacturing cost is reduced substantially.

End portion-treating method for synthetic resin film and device therefor

Disclosed is a process for continuously mixing two liquid components, whose one liquid component is a two-liquid curing type resin which comprises continuously supplying one liquid component under stirring into a mixing container and pouring the other liquid component into said container by pushing open a needle forcibly provided to a check valve, the improvement wherein said needle is pushed open with a non-curing liquid, thereafter, a curing liquid is poured into said mixing container. According to the present invention, when, for example, a polyamide acid and a curing agent are caused to mix and react with each other, a transparent polyimide mixed uniformly is obtained and high quality molded articles of polyimide are provided therefrom.

Process for continuous mixing of a two-liquid curing type resin

The present invention provides a polyimide resin laminate of one layer of a polyimide resin film and one or more layers of activated fluorine resin films, wherein undulations of 0.03-5 .mu.m are formed on the outer surface of the fluorine resin films. According to the present invention, the slidability of the laminate is improved, trouble in the course of taping due to poor slidability is prevented, the taping workability is markedly improved and an improved quality of polyimide laminates is provided.

Polyimide resin laminate improved in slidability

Disclosed is a continuous two-liquid type mixer comprising:

Continuous two-liquid type mixer

A process for preparing foodstuff having continuous fiber structure which involves forming a wet mixture by adding meat stuff and/or other foods to wheat gluten alone or to a mixture of wheat gluten with other vegetable proteins, stretching the wet mixture, and heating the wet mixture in a high-temperature dry atmosphere, wherein steam is mixed with air alone or with a mixture of air and an inert gas, and the relative humidity is maintained within the range of 75 to less than 100%.
