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： Disclosed is a process for pelletizing high melt flow crystalline polymers to produce crystalline pellet products. The process includes feeding a polyolefin granular or pelleted polymer into a melting/mixing mechanism to provide a molten polymer material. The molten polymer material is optionally passed through a melt pump and through a die to form a plurality of molten polymer strands. The plurality of molten polymer strands then are passed through or along a water trough declined with respect to the direction of the horizontal arrays where they are sprayed with cool liquid a plurality of times in such a manner that the sprayed cool liquid creates turbulent flow and disturbs a thin film of hot water and/or steam that forms around each molten polymer strand as it is cooled without undesirable axial acceleration of the polymer strands. Subjecting the molten polymer strands to such a cooling procedure produces cooled polymer strands, which then are fed to a cutting mechanism and cut into pellets. The process produces ultra high melt flow crystalline polymer pellets which are uniformly compounded.

摘要： Apparatus and method for producing a hollow plastic section by extrusion through a die in a horizontal direction. The die has an inner mandrel which forms the cavity in the section. A first sealing plug and a second sealing plug, which sealing plugs are situated at a distance from one another downstream of the inner mandrel are attached to the inner mandrel. The sealing plugs are designed, during operation of the apparatus, to lie in the hollow section, such that they are sealed against the section, so that the sealing plugs and the section delimit a compartment in the cavity of the section. The compartment is filled with a liquid during operation of the apparatus. Vent means are located in the compartment for receiving and discharging gases or vapor which collects at the highest point of the compartment.

摘要： In a melt spinning apparatus, cooling system with a blower nozzle with slit-shaped outlet openings is used which is directed upon the yarns emerging from the spinning nozzle. The blower nozzle is provided with a bend immediately before its outlet opening through which the air stream is directed to the output of the yarns from the spinning nozzles. The bend is designed so that a rapid and effective cooling of all the extruded filaments takes place, even with a nozzle package with a large number of perforations, without having to provide several blower nozzles. A narrowing at a given distance before the outlet opening ensures even distribution of the flow profile produced over the entire outlet cross-section of the blower nozzle. Furthermore, the spinning nozzles are assigned an induction heating system in which induction coils are placed above the area over which the spinning nozzles extend.

摘要： A process for forming a rod of bioabsorbable polymeric material includes extruding the material at a temperature above its melting point at a controlled rate of between 0.4 to 20 feet per minute to form a continuous rod. The continuous rod is then cooled by passing the rod through a cooling bath to cause nucleation. The continuous rod is passed through a first puller running at least at the same speed as the extruder. A second puller is provided which is moving faster than the first puller so that the continuous rod is elongated at a ratio of between 2 and 12 times. During this elongation, the rod is heated to a temperature of between 55° C. and 140° C. in an oven located between the first and second pullers. The rod is annealed at a temperature of between 70° C. and 110° C. after being elongated but prior to exiting the second puller. Upon exiting the second puller, the tension in the rod is released and the continuous rod is then allowed to cool. A cutting station is then provided to cut the continuous rod into desired lengths.
