Title: Apparatus and method for manufacturing film
Inventor: SHIMIZU KAZUYUKI
IPC: B29K33/04
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a film of high quality with a specific thickness and film thickness accuracy by casting a dope of a raw material solution in a die having a specific gap between a support and an opposed slit to form a web on the support, releasing the web, drying the web while conveying, and winding the web. SOLUTION: A dope of a casting band 2 is cast in a casting die 10 to form a web W of a uniform thickness. The web W is released from the circulating band 2, and fed from a drying box 4 to a drying box 5. The web W is completely dried in the boxes 4, 5 to a film F having a thickness of less than 85 μm, which is wound by a winding core 6 provided at an end of a manufacturing line to a wound film roll. A slit gap of the die 10 is set to 50 to 1,500 μm, and a flow-out state of the dope from the slit is stabilized without largely changing. Thus, the film having the thickness of less than 85 μm, high film thickness accuracy of high quality, no stripe, no coating and no foreign matter is obtained.
