摘要： An extruder according to the invention comprises at least two annular conical feed gaps (9) one within the other, formed between a rotatable rotor (1) and a stator (4, 5). At lest some of the material to be extruded is subjected in the different feed gaps (9) of the extruder alternately to a higher pressure and then to a lower pressure. The rotor (1) or stator (4, 5) between the feed gaps (9) can then be balanced such that the pressure effect provides a hydrodynamic bearing, whereby, when the extruder is used, even at worst a very small force is exerted on the other bearings of the rotor (1) or stator (4, 5). By the method of the invention, a product can also be produced which contains cross-linked and at least partly oriented polyethylene.

摘要： The invention relates to a method and an arrangement for cooling an extruded hollow product. According to the invention, the extruder (1) is provided with means for sucking air through the pipe (2). The air to be sucked is thus in contact with the inner surface of the pipe (2), cooling the pipe from the inside. Therefore the cooling of the pipe (2) can be realized in an efficient and simple manner. By arranging the sucking to occur from the middle of the conical extruder (1), no weld line will be formed in the extruded product, and the extruder (1) can be cooled effectively from the inside. According to the invention, the heat contained by the air that has been sucked through the pipe (2) can also be utilized.

摘要： A method for making a product to be extruded and an extruder. The extruder has at least two conical stators and at least one conical rotor placed rotatably between the stators. The extruder further has supply conduits for feeding the material to be extruded separately into the exterior and interior of the rotor. Each supply conduit is provided with a separately adjustable feeding device by means of which the amount of material flow to be supplied can be adjusted. The degree to which the space between the rotor and the stator is filled and the amount of the heat generated by friction can be regulated. Further, the ratio of the material flows in the different supply conduits determines the ratio of the thickness of the layers obtained. The method and extruder according to the invention make it possible to regulate the properties of a final product easily and in several different ways.

摘要： A method for extruding an extrudable material to form an extruded product, the method including the steps of (a) providing an extruder having a periphery and at least a first stator, an outer rotor and an inner rotor, the first stator being disposed between the outer rotor and the inner rotor to define at least two annular feed gaps disposed one within the other in a radial direction within the periphery of the extruder, a first of the at least two annular feed gaps being defined by the outer rotor and the first stator and being disposed outside of the first stator between the first stator and the outer rotor with the outer rotor being closer to the periphery than the first stator, the first feed gap being the outermost feed gap in the extruder, the extruder including a supply conduit for supplying the material to the first feed gap through the first stator; and (b) supplying the material to the at least two annular feed gaps, with at least a part of the material being supplied through the first stator to the first feed gap, to cause the material to be extruded.
