Abstract:
1. An inner deckle for a die, comprising: a shaft-shaped deckle main body having an outer surface shape corresponding to a shape of a manifold; and a sheet- or film-shaped deckle auxiliary portion which is extended from the deckle main body and has an outer surface shape corresponding to a shape of a slit, the inner deckle being arranged at each end of a die, the die including: a die piece formed by combining a pair of split die piece members, the die formed with: the manifold extending in a longitudinal direction of the die piece; and the slit extending from the manifold radially outward toward a direction of the die piece, wherein the deckle main body includes, in at least a part of a region where the deckle auxiliary portion is arranged, a seal reinforcing portion for reinforcing liquid-tight sealing of a liquid material for coating or extrusion, wherein the liquid material is supplied into the manifold, and the seal reinforcing portion includes at least one sealing member including two or more films; the films slide and are simultaneously elastically deformed in the form of a falling deformation thereof against an inner wall of the manifold when a position of the inner deckle is moved with respect to the die; and 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.
