Techniques involve a machine system for producing or treating synthetic threads, comprising a plurality of machine components, having actuators and/or sensors, that are associated with a plurality of control components. The control components are connected by a machine network to a central machine control station. In order to remedy process disruptions as quickly as possible and to ensure uniform product quality, the control components are coupled in parallel to a central analysis station by an analysis network.

An installation for producing a polymer melt for a porous film, in particular for a membrane film, comprises a planetary roller extruder. Said extruder is used to produce a flowable polymer melt from thermoplastics. The planetary roller extruder has a filling opening and a discharge side for delivering the polymer melt. A melt pump is further provided. The discharge side of the planetary roller extruder is connected to a downstream inlet side of the melt pump for further conveying the polymer melt. The connection is in the form of a pressure channel shielded from the ambient atmosphere or a pressure line shielded from the ambient atmosphere. The planetary roller extruder and the melt pump are designed and/or can be driven in such a manner that the polymer melt is applied or can be transferred under pressure at the melt pump on the inlet side.

A method of recycling a PET-containing material comprises: (1) providing an MRS extruder having an MRS section comprising a plurality of satellite screws and an outlet; (2) providing a vacuum pump in communication with the MRS section; (3) providing a spinning machine comprising an inlet, wherein the inlet is directly coupled to the outlet of the MRS extruder; (4) heating a plurality of PET-containing flakes in the MRS extruder to form a PET-containing melt; (5) increasing a surface area of the PET-containing melt by distributing the PET-containing melt across the plurality of satellite screws in the MRS extruder; (6) drawing off vapors from the PET-containing melt by reducing the pressure in the MRS section with the vacuum pump; (7) collating the PET-containing melt in the MRS extruder; and (8) extruding the PET-containing melt through the outlet of the MRS extruder into the inlet of the spinning machine.
