摘要： PURPOSE:To provide an enclosed kneader, which can be used both with equal rotational frequencies and with different rotational frequencies of two rotors. CONSTITUTION:In an enclosed kneader, in which two rotors connected with the two output shafts 1 and 2 of a speed reducer 18 are disposed in an array under their non-engaged state with each other in a tubular enclosed space having a crosssection consisting of two circles intersecting with each other, are rotated in directions different from each other, the two rotors are made to be used both with equal. rotational frequencies and with different rotational frequencies by changing over the rotational frequencies of the two output shafts of the speed reducer 18 from or to equal rotational frequencies to or from different rotational frequencies.

摘要： PURPOSE:To improve gripping and extruding capacity of a material in a feed part by a method wherein two screws which are flush with each other are arranged in parallel with each other, a hopper is arranged extending over feed parts of the screws each and a length of a compression part to the diameter of the screw is specified. CONSTITUTION:Two screws 2 which are flush with each other are arranged within a casing 1 in parallel with each other and turnably and a hopper 3 is arranged extending over feed parts 5 of the two screws each. Screw blade 7 is formed on the feed part 5 and a compression part 6 of the screw 2. A screw pitch of the blade 7 is an unequal pitch where its feed part 5 is long and compression part 6 is short and when size of the outside diameter and a length of the compression part 6 are D and L respectively, they are set up in a formula of L/D=0.3-0.6. The two screws 2 are in an engaged or nonengaged state and they are provided arrangeably by changing a phase by 0 deg. or 180 deg. (provided that this is of an angle formed by the screw blade 7 on the same section meeting at right angles with an axis) in accordance with contents of composition and characteristics of an extruded material.

摘要： PURPOSE:To prevent a floating weight from damaging by giving stabilized effect to the floating weight, by controlling a position of a piston in the inside of a cushion cylinder at the most suitable position always. CONSTITUTION:A cushion chamber 29 divided by a piston 28 is formed within a cushion cylinder 27 and a relief valve is provided so that the inside of the chamber 29 becomes constant pressure always. The cushion cylinder 27 is provided with a detecting device 48 detecting a relative position relation between the cushion cylinder 27 and the piston 28. The detecting device 48 detects a matter that on any of positions such as the upper and lower part positions and their middle part position of the cushion cylinder 27 does the piston 28 lie and controls the piston 28 in the chamber 29 through action of a motor 39. As a cushioning allowance of the cushion chamber can always be made more than a predetermined quantity, equipment can be made compact.
