A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

The invention relates to a screw extruder (29) having a housing (30) comprising an intake housing (4), a degassing housing (5), and at least one housing bore (21, 22) running in the interior of the degassing housing (5) and implementing at least one internal wall segment (25; 26; 27; 28) of the degassing housing (5) and serving for receiving at least one auger shaft (7), and wherein the at least one wall segment (25; 26; 27; 28) of the at least one housing bore (21, 22) comprises at least one partition wall (13, 33) protruding into the at least one housing bore (21, 22) in the region of the degassing housing (5), and wherein at least one filter element (8) is disposed in the interior of the degassing housing (5) and at least partially encompasses the at least one auger shaft (7) and bears on the partition wall (13) in regions for implementing at least two spatial pressure regions (11, 12) sealed off from each other.

A device for processing thermoplastic plastic includes a storage container for receiving pieces of plastic particles or a conveying line for conveying the pieces of plastic particles, and a conveying screw following the storage container/the conveying line at a transfer opening. The device also includes an extruder following the conveying screw and an air outlet arranged opposite the transfer opening and directed at this opening. In a method for operating the device, an air stream is aligned with the transfer opening. The strength and/or the direction of the air stream is adjusted or controlled as a function of a load on the extruder.

An extruding system includes a melting unit configured to convey a polymeric material, a mixing unit configured to mix the polymeric material with a blowing agent to form a mixture, an injection unit configured to inject the mixture, a first flow control element disposed between the melting unit and the mixing unit, and a second flow control element disposed between the mixing unit and the injection unit. A method of extruding includes conveying a polymeric material from a melting unit to a mixing unit, conveying a blowing agent into the mixing unit, mixing the polymeric material with the blowing agent to form a mixture, conveying the mixture from the mixing unit to an injection unit, and discharging the mixture from the injection unit, wherein flow of the polymeric material is controlled by a first flow control element, and flow of the mixture is controlled by a second flow control element.

A device for producing a dyed plastic melt and an undyed plastic melt includes a multi-shaft screw extruder, a first metering installation, a second metering installation, and a control installation for selecting between a first operating mode for producing the dyed plastic melt and a second operating mode for producing the undyed plastic melt. The first metering installation serves for feeding an undyed plastic material through a first infeed opening into a housing of the multi-shaft screw extruder, and the second metering installation serves for feeding at least one dyeing agent through a second infeed opening into the housing. In order for the undyed plastic melt to be produced, the plastic material is fed exclusively via the first infeed opening such that residual dyeing agent which is still located in the second metering installation or in the region of the second infeed opening does not contaminate the undyed plastic melt.

An EVOH resin composition excellent in inorganic compound dispersibility and a method of producing an EVOH resin composition excellent in productivity and inorganic compound dispersibility are provided. The EVOH resin composition contains an EVOH resin (A) and an inorganic compound (B), and has a crystallinity of not lower than 36%. The EVOH resin composition is produced by: feeding an EVOH resin (A), an inorganic compound (B) and water (C) into a kneading apparatus including a screw-type side feeder (3); melt-kneading the resulting EVOH resin mixture while driving the screw-type side feeder (3); and expelling water vapor from the screw-type side feeder (3) to reduce the water content of the EVOH resin mixture to lower than 5 weight % while suppressing leakage of the EVOH resin kneaded body from the screw-type side feeder (3).
