Abstract: An inner deckle for a die includes a shaft-shaped deckle main body and a sheet- or film-shaped deckle auxiliary portion extending from the deckle main body. The inner deckle is arranged at each end of a die. The die includes a die piece and is formed with a manifold and a slit. The deckle main body includes a seal reinforcing portion. A liquid material is supplied into the manifold. The seal reinforcing portion includes at least one sealing member having two or more films. The films slide and are simultaneously elastically deformed against an inner wall of the manifold when a position of the inner deckle is moved with respect to the die. The films cooperate with each other and are closely attached to the inner wall by an elastic restoring force when the position of the inner deckle is fixed with respect to the die.

Abstract: A die-type coating device includes a supply roll, a die, a rewinding roll, web widthwise end position detection devices, and layer widthwise end position detection devices. The die includes a pair of inner deckles which adjust a coating width. The inner deckle is arranged at one of two end portions of the die and configured to be easily moved in the die in a longitudinal direction of the die. The die includes a drive device which drives and moves the inner deckles. The drive device is driven on a basis of information on both widthwise end positions of the web detected by the web widthwise end position detection devices and information on both widthwise end positions of the layer of the coating liquid or the coating layer detected by the layer widthwise end position detection devices so that respective positions of the inner deckles relative to the die are changed.
