Title:
APPARATUS FOR MAKING HOLLOW BODY BY ROTARY MELTING FROM FLUID DRIED THERMOPLASTIC SYNTHETIC RESIN
Document Type and Number:
Japanese Patent JP3761222
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for making dried fluid synthetic resin or particularly cellulose derivative by rotary melting.
SOLUTION: An inner chamber 1c and a hollow chamber 4 existing between flanges 3a and 3b at the front and rear of a mold 1 can be coupled to a negative pressure generator via a tube conduit 7 provided in the rotary shaft 6 of the mold via one tube conduit branches 7a, 7b, and can be coupled to a protective gas chamber for eliminating the negative pressure in the inner chamber of the mold. On the other hand, the hollow chamber existing between the flanges is stopped in the state that the chamber is coupled to the generator.
