摘要： A screw used in an extruder and an extruder having such a screw, in particular a screw used in a multiple-screw extruder and a multiple-screw extruder uses an additional connecting element directly leading from one segment to the next in order to relieve the mandrel. The screw includes a mandrel and a plurality of segments borne by the mandrel and arranged axially with respect to one another, a segment border between a first segment and an axially adjacent second segment has a separate cylindrical connecting element adapted to transmit a torque over the segment border. The ratio of a length of the connecting element to the diameter of the connecting element is higher than 11.

摘要： A system according to various embodiments can include a source for supplying a material to be treated, an extruder, at least two screws, and a drive coupled to the screws for axially rotating the screws. The extruder includes an inlet for receiving the material, which is fed therein in a controlled manner. The screws are provided within the housing of the extruder. The screws have a plurality of compression and release stages that create mechanical heat which is directly applied to the material to change the mechanical properties of the material thereby facilitating a conversion of a physical state of the material from a non-compactable state to a compactable state as the screws rotate and move the material longitudinally along the screws to produce a final product, for example, a feed tub for use as an animal feed.

摘要： A screw includes a screw main body, a conveyance portion conveying a raw material, and a passage provided in the screw main body. The passage includes a first passage element, a second passage element, and a third passage element. The screw main body has a plurality of cylindrical bodies arranged in an axial direction of the rotating shaft. At least a portion of the conveyance portion is formed on outer peripheral surfaces of the cylindrical bodies adjacent to each other, and the passage is formed in the cylindrical body so as to cross over between the adjacent cylindrical bodies.

摘要： A screw for use in an extruder or in a twin screw extruder exhibits a mandrel and a number of segments held on the mandrel disposed axially to one another. Between the mandrel and a segment, a separate torque entrainer is disposed. The torque entrainer is in contact with the mandrel at a contact surface area of the mandrel, wherein the contact surface area is notch-free.To transmit the high occurring torque, the elements are connected to the mandrel in a positive-locking manner and also axially braced.

摘要： According to a process for producing a thermoplastic resin film according to one aspect of the present invention, a molten resin, while the molten resin is discharged from a die and thereafter lands onto a cooling roller, is uniformly heated in a direction of a flow by a heater. Thereby, a thermoplastic resin film having very slight thickness unevenness in a longitudinal direction can be formed. Moreover, according to the process for producing a thermoplastic resin film, heating by the heater can reduce a viscosity of the molten resin at the time of landing, and can suppress generation of retardation at the time of landing.
