摘要： Buffer means 20Z consisting of an expansion conveyor 20a, inverted conveyor 20b and expansion conveyor 20c is interposed between the conveyors 24 and 25 of a conveying unit 20 so that when a trouble occurs in a receiving unit 30, the expansion conveyors 20a and 20c of the buffer means 20Z are expanded to extend the conveying line, and the extruder revolution R and the conveyor speed V are changed to reduce the conveying speed not to carry the extruded treads 1 to the receiving unit 30. When the above trouble is solved, the conveying line of the buffer means 20Z is made the shortest, and the extruder revolution R and the conveyor speed V are changed to increase the conveying speed so as to carry the buffered extruded treads to the receiving unit 30.

摘要： Presented is a process to purge film extrusion systems with at least one extruder (A, B, C, D) for the purpose of changing batches, wherein the speed is changed periodically in at least that part of the extruder, wherein the material is changed. By considering the mass flow rate of the film extrusion system, advantageous improvements of the process avoid the situation in which the film tears off. To this end, at least one selected guide extruder (A) is operated at a speed, which is increased as compared to the normal operation, and at least one selected downstream extruder (B, C, D) is operated at a speed that is decreased as compared to the normal operation. Furthermore, control and operating units (1) and extrusion systems to carry out the process, which include, among other things, means for an automated program run of the purging program and the optical display of the parameters of the same, are presented. The described purging processes result in the production of films having a specific cross section.

摘要： The method uses color to determine the wear of the screw and barrel of the molding machine. The method measures the color and/or color variation to determine the wear. A first material of a first color and a second material of a second color are fed into the machine to create a third material with a third color. The third material is either extruded to form a part or is injected into a mold to form a part. The color of the part is then measured with a measuring device, such as, spectrophotometer. The color will change as the screw and barrel wear. The color value would then be compared with previous color values to determine the amount of wear.

摘要： Improved melt spinning of friable, thermally sensitive organosilicon preceramic polymers is obtained by using externally-metered feed means for continuous feeding of the polymer to an extruder. Starve feeding by metering the feed at a rate less than that required to fill the feed screw flights prevents pulverizing and compaction of the friable polymer, leading to cross-linking of trapped polymer and solid plugging, which would cause the extruder to bind and cease to function. Metered feed can be obtained by either monitoring of screw loading or discharge pressure and adjustment of hopper feed rate or control based upon measured values of extruder speed or metering pump speed.

摘要： In a method of extruding a food product wherein starting products and water are fed to an extruder and mixed in a mixing zone and wherein the mixture is heated and plastified by the supply of shearing energy and, after passing through a nozzle, is foamed, in order to achieve a product quality which remains constant independently of alterations in the properties of the starting products and external disturbing factors, it is provided that, with a constant speed of rotation of the shaft or shafts of the extruder, the drive power (N) applied to the shaft or shafts by the drive motor is measured, that the bulk throughput (m) of the starting products supplied is measured, that the quotient (s) of these quantities (N,m) is formed in a computing device and that this specific energy (s) thus determined is fed, as a controlled quantity, to a controller which keeps it constant in accordance with a preset desired value (s.sub.Soll) in such a manner that the supply of water to the mixing zone of the extruder and/or a supply of steam are influenced as correcting variables by the controller.
