流延装置、溶液製膜方法及び溶液製膜設備
Document Type and Number:
Japanese Patent JP5022270
Kind Code:
B2
Abstract:
A casting drum is rotated around a shaft. A peripheral surface of the casting drum moves in an X direction. A dope is discharged through a casting die onto the peripheral surface. A casting bead is formed so as to extend from a discharge port of the casting die to the peripheral surface. A decompression chamber decompresses an upstream side from the casting bead. Air flowing toward the casting bead is generated at the vicinity of the peripheral surface. A lateral labyrinth plate is disposed at a clearance between the decompression chamber and the peripheral surface. The lateral labyrinth plate is provided with a labyrinth groove extending along a width direction of the casting bead. An edge portion for forming the labyrinth groove has a cross section with an acute angle in a direction of air flowing between the decompression chamber and the support.
