Abstract: With conventional closed kneaders, the temperature of the kneaded material remains high at the end of primary kneading because insufficient cooling is made in the interior part of the kneaded material, making it necessary to either provide cooling time between the primary and secondary kneading or to transfer materials to another kneader after the end of primary kneading for the secondary kneading. This has constituted an obstruction to productivity. In view of such problems, a closed kneader is capable of controlling the kneaded material temperature at the end of primary kneading at a level no higher than the temperature that allows addition of a vulcanizing agent line, and can perform secondary kneading immediately after the end of primary kneading. In a closed kneader provided with a chamber for storing kneaded material and a pair of rotors installed in the chamber, the proportion of the radius of the rotor shaft to the radius on the inner face of the chamber is kept at no less than 0.65.

Abstract: The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation.
