摘要： A method for processing plastics material, in particular thermoplastic material, such as plastics recycling material and/or plastics waste, is disclosed comprising the following steps: supplying the plastics material into a screw-conveyor machine); supplying an additive for converting organic chlorides into inorganic chlorides into the screw-conveyor machine; plasticizing the supplied plastics material with the screw-conveyor machine to form a plastics melt, and mixing the plastics melt with the supplied additive with the screw-conveyor machine to form a mixture, wherein at least some of the organic chlorides contained in the plastics melt are converted into inorganic chlorides with the additive. A corresponding device for processing plastics material, in particular thermoplastic material, such as plastics recycling material and/or plastics waste, using a screw-conveyor machine is also disclosed.

摘要： The extrusion installation is configured for manufacturing a complex profiled-element strip, such as a tread, based on elastomer compounds by co-extrusion, and comprises multiple extruders feeding elastomer compounds to an extrusion head. The extrusion head receives a proportion of elastomer compound of between 2 and 25% of the total volumetric throughput of the installation from at least one Archimedean-screw extruder and the rest from positive-displacement extruders.

摘要： A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

摘要： The present invention is directed to an apparatus for forming a multi-layer web formed from at least two polymeric film tubes in intimate contact with each other but not bonded to each other. The apparatus includes the use of a blown film extrusion die that extrudes two separate blown film polymeric tubes via two separate annular die lips. A fluid cooling system applies cooling fluid across a plurality of surfaces of the two blown film tubes. One of the die lips may be at a different height from the other die lip. The frost line of one blown film tube may be at a different height from the other blown film tube.

摘要： A plastic melt machine includes a feed screw rotatably mounted in a barrel and driven in rotation about a longitudinal screw axis of the feed screw by a screw drive to plasticize material, and an apparatus for driving a device independently of the feed screw. The device can be any rotatable device associated with the feed screw wherein the device is rotatable about a drive axis and is in fluid communication with the barrel to receive the plasticized material. The drive axis is one of parallel to and offset from the screw axis and extending at an angle relative to the screw axis. A drive shaft couples the device to the device drive for rotating the device independently of the rotation of the feed screw by the screw drive.
