摘要： An extrusion system and method uses an accumulator to control and use excess plastic melt. The accumulator is situated between an extruder and a gear pump. The accumulator includes an accumulator housing to store excess plastic melt from the extruder and an accumulator spring connected to an accumulator piston to subsequently send the excess plastic melt to the gear pump. In another embodiment, the accumulator includes an accumulator housing to store excess plastic melt from the extruder and a hydraulics system to send the excess plastic melt to the gear pump. The accumulator can be a first in first out (FIFO) device having a melt passage through the accumulator piston. The system and method are used particularly advantageously in Alternate Polymer extrusion installation in which gear pumps regularly increase and decrease their speed but in which the melt-supplying extruder cannot accommodate such rapid speed changes.

摘要： An alternate polymer extrusion method and system reduces “drool” effects that detract from precise control over the content of two or more materials in an extrudate along its length. In the system, two or more extruders direct melt to two or more gear pumps. Control of the speed of the gear pumps controls the amount of each material emergent from the pumps, proceeding to a convergence in the paths from the pumps and thence to a die. Melt in each path between each pump and the convergence tends to expand and drool into the convergence as its associated pump is slowed and stopped. To prevent this, in the die, a constriction in each path just upstream of the convergence greatly reduces drool past that point by requiring a much greater pressure to force the melt past the constriction. The increased pressure required increases compression and expansion of the melt between the pump and the construction as a pump starts or increases in speed, on one hand, and stop or decreases in speed, on the other hand. Compensatory pump speed changes are made to counter this effect.

摘要： An apparatus for processing thermoplastic synthetic plastic material to be recycled comprises a first receptacle (1) and a second receptacle (2) for the material to be processed. Within both receptacles (1, 2) tools (21) for mixing and heating the material circulate around a vertical axis each. The material reaches the second receptacle (2) which is connected to an evacuating means (9), from the first receptacle (1) through a connecting conduit (3). The first receptacle (1) has above it an intake opening (19) for the material to be processed, and the mouth of the connecting conduit (3) in the second receptacle (2) is disposed at a higher level than the tools (21) circulating in this receptacle (2). The material processed is carried off the second receptacle (2) through a discharge opening (49) by means of at least one screw (47), whereby this receptacle is vacuum-tightly closed. A sluice (6) is connected to the intake opening (19) of the first receptacle (1) that also is connected to an evacuating means (9). In both receptacles (1, 2) at least two tools (21) each circulate in different levels, disposed one upon the other, wherein the intake opening (19) in the first receptacle (1) is disposed higher than the uppermost tools (21) circulating in this receptacle (1). The discharge opening (49) of the second receptacle (2) is disposed at least substantially at the level of the lowermost tools (21) circulating in this receptacle (2). In each one of the two receptacles (1, 2) at least one temperature sensor (32) is provided for each plane of the circulating tools (21), which sensor is disposed higher than its associated plane.

摘要： The invention relates to an apparatus for extruding a polymer profile directly onto the surface of a glass plate and particularly along a peripheral edge thereof. The extruded polymer profile is provided with a sealing and centering lip located on and projecting over the circumferential peripheral surface of the glass plate. The extrusion die has at least one supply channel for the polymer to be extruded. One supply channel or portion thereof leads the polymer material substantially to the portion of the die orifice directed toward the center of the plate. The other supply channel essentially supplies the portion of the orifice directed toward the outside. The supply channel may be provided with a shutoff device which regulates the volume flow. The regulation of the shutoff device takes place as a function of the radius of curvature (R) of the path covered by the extrusion die.

摘要： A method for extruding, stretching and sintering polytetrafluoroethylene in a single pass operation to form tubular articles of low density, low matrix tensile strength, sintered polytetrafluoroethylene and articles such as electric cable having low density, low matrix tensile strength sintered polytetrafluoroethylene insulation applied about a conductor by such method. A high reduction ratio rating polytetrafluoroethylene powder with a lubricant is extruded by an extruder having a low reduction ratio, and the extrudate is heated to remove the lubricant and is stretched prior to sintering of the polytetrafluoroethylene tube which is held in its previously stretched state during sintering.
