Abstract
A process and apparatus for solvent casting which comprises, casting a polymer solution onto a casting support, cooling the polymer solution to gelatinize on the casting support to form web, stripping off the web from the casting support, thrusting side edges of the web into pins of a pin tenter by an inserting device, and drying the web while conveying the web with carrying the side edges of the web by the pin tenter, wherein the inserting device is cooled so that the surface temperature of the web in contact with the inserting device does not exceed a gelation temperature of the polymer solution are proposed. The present invention makes surely to convey the web without slipping from the pin tenters even when the pin tenters convey the web at a high speed. As a result, the productivity of film can be improved.
