Latest Patents

One of Tetsuo Nasu's notable patents is the "Inner deckle for die and die." This invention features a shaft-shaped deckle main body and a sheet- or film-shaped deckle auxiliary portion that extends from the main body. The inner deckle is strategically positioned at each end of a die, which consists of a die piece formed with a manifold and a slit. The deckle main body includes a seal reinforcing portion that incorporates at least one sealing member with multiple films. These films are designed to slide and elastically deform against the inner wall of the manifold when the inner deckle's position is adjusted. When fixed, the films work together to create a tight seal against the inner wall, thanks to their elastic restoring force. This innovation is crucial for the effective supply of liquid materials into the manifold.
