摘要： The invention relates to a method and an apparatus for making a plastic film, and to a plastic film. The invention comprises extruding a film (5) from plastic material (5a) by an extruder (1) and orientating the film after extrusion. Material is mixed into the plastic (5a) so that when the plastic film (5) is stretched, cavitation bubbles are formed in the material particles mixed into the plastic (5a). After orientation gas is arranged to act on the plastic film under high pressure so that the gas diffuses in the cavitation bubbles and causes overpressure in them. Thus it is possible to make a thin foamed film (5) with a foaming degree of over 70 %.

摘要： An extrusion method and an extrusion device, whereby at least two different flows of material are supplied from the extrusion device (1) to a nozzle (7). The nozzle (7) comprises at least two nozzle chambers (13, 14) such that the material flowing through the first nozzle chamber (13) forms an outer part (15a) of a product (15), and the material flowing through the second nozzle part (14) forms an inner part (15b) of the product (15). The capacity of the nozzle chambers (13, 14) is changed, whereby the relative proportion of the different parts (15a, 15b) of the product (15) can be varied. When the capacity of the nozzle chamber (13, 14) is decreased, the amount of material flowing therethrough increases at the outlet of the nozzle (7), and when the capacity of the nozzle chamber (13, 14) is increased, the amount of material flowing out therethrough decreases at the outlet of the nozzle (7).

摘要： The invention relates to a method and an apparatus for preparing an extrudable product, and an extruded product. An extruder according to the invention comprises at least two annular feed gaps (4) between which there is a stator (3), and a rotatable rotor (1) is provided outside the outermost feed gap (4). Inside the stator (3) there is at least one rotatable rotor (2). The product to be extruded can thus be provided with radial orientation without a separate orientation unit. By supplying continuous fibres (20) for example through the stator (3) it is possible to prepare a very strong product that is radially oriented and that comprises axial continuous fibres (20) as reinforcement.

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 film (5) is extruded from plastic material by means of an extruder. Material is mixed into the plastic (5a) of the plastic film (5) before the extrusion so that cavitation bubbles are formed in the material particles mixed into the plastic (5a) when the plastic film is stretched. The film (5) is orientated by stretching. After the extrusion the plastic film (5) is cooled slowly below the crystallization point of the plastic material before the orientation.

摘要： The present invention relates to a method and an apparatus for treating waste material, which apparatus comprises a conical rotatable rotor (3) placed between stators (1, 2). At least the stators (1, 2) have recesses (9) by means of which the material in the apparatus can be discharged therefrom when the rotor (3) is rotating. The rotor (3) has several openings (8a, 8b) in the axial direction of the apparatus through which openings at least some of the material is arranged to pass. The edges of the recesses (9) and the openings (8a, 8b) of the rotor (3) are sharp in such a manner that the waste material supplied to the apparatus is ground by means of the sharp edges when it passes through the openings (8a, 8b).
