摘要： A process to purge film extrusion systems with at least one extruder for the purpose of changing batches, wherein the speed is changed periodically in at least that part of the extruder in which 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 is operated at a speed which is increased as compared to the normal operation, and at least one selected downstream extruder is operated at a speed that is decreased as compared to the normal operation.Also included are control and operating units and extrusion systems to carry out the process, which include, among other things, the elements necessary for an automated program run of the purging program and the optical display of the parameters of the same.

摘要： A method for producing powder mixtures capable of inducing an even more intimate, microhomogeneous intermixing in a heterogeneous powder composed of at least two types of powders. The method is effective even for the mixing of an aggregable powder and a nonaggregable powder. According to the method, a heterogeneous powder composed of at least two type of powders that have been preliminarily mixed by stirring is introduced into an inlet while a rotating axle is turning and is axially transported within a cylinder by a screw. As the heterogeneous powder passes between rotating disks and fixed disks, it is subjected to a highly efficient mixing by compression and shear forces due to a sliding-shear action exerted between depressions and elevations installed on the opposing surfaces of the rotating disks and fixed disks. The mixture passes in sequence through multiple stages of the rotating and fixed disks. A powder mixture, which has been microhomogeneously interdispersed, is discharged from the outlet.

摘要： A lubricating layer is fixed on the wall of the discharge orifice of a continuous internal mixer of the kind wherein the internal pressure of the material being mixed in controlled by the choking effect of this orifice on the material discharged therethrough whenever new material us fed into the mixer. This provides a smoother restraint of the discharging material and therefore more uniform control of the pressure on the material while it is in the mixer.

摘要： The invention relates to a process for the production of articles, exemplarily a plastic article, by means of an extruder (1) to which a first plastic composition of a first main component and at least one associated minor component is supplied from a first group of dosing stations (21, 24). According to the invention, during the production time of a first production order there is prepared a second group of dosing stations (31, 33) at the extruder for a second production order for which a second plastic composition of a second main component and at least one associated minor component that is different from the first plastic composition has to be supplied to the extruder. After completion of the first production order it is reset to the second production order by terminating the supply of the first plastic composition by closing a first shut-off device (8) and starting the supply of the second plastic composition by opening a second shut-off device (8′).
