摘要： A polyamide resin is produced through polycondensation by melt-kneading a polyamide oligomer having a relative viscosity of from 1.1 to 1.3 and a water content of 3% by mass or less in a cylinder (S) of an extruder. The extruder includes open vents (OV1) and (OV2) and vacuum vents (V1) and (V2). The open vent (OV1) is arranged near a supply port (A3), e.g., above the supply port (A3), and a pressure-decreasing element (Y) is arranged on an upstream side with respect to positions of the vacuum vents (V1) and (V2). In addition, the open vent (OV2) is arranged in a preceding area (OA) and is brought into a pressurized state.

摘要： A method for forming a cylindrical rubber member includes bringing a die 11 close to a forming drum 2, forming a winding start portion S1 by extruding a rubber S and simultaneously starting to rotate the forming drum 2 to gradually increase an extruding amount to an amount Q1 and gradually increase a distance between the die 11 and the forming drum 2 to a distance D2 corresponding to a desired thickness of the cylindrical rubber member, winding the rubber S by maintaining the extruding amount at the amount Q1, and maintaining the distance between the die 11 and the forming drum 2 at the distance D2, and forming a winding end portion S2 on the winding start portion S1 by maintaining the distance between the die 11 and the forming drum 2 at the distance D2 and gradually reducing the extruding amount from the amount Q1.

摘要： The invention relates to mixing elements having an increased number of base geometry periods per longitudinal section and an improved dispersing effect for multi-shaft screw extruders comprising screw shafts that co-rotate in pairs. The mixing elements have clearances that are configured according to the method of spatial equidistants or according to the method of longitudinal equidistants. The invention further relates to the use of the mixing elements in multi-shaft screw extruders, a corresponding screw extruder comprising the mixing elements, and a method for extruding plastic masses.
