Extrude undried P ET with Low I.V. loss.Vacuum-vented twin-screw twin-screw adj. Nautical Having two propellers, one on either side of the keel, that usually revolve in opposite directions. extrusion of undried PET can produce sheet with I.V. similar to that obtained with predried PET on a single-screw extruder. So says Battenfeld Extrusionstechnik in Germany Germany (jûr`mənē), Ger. Deutschland, officially Federal Republic of Germany, republic (2005 est. pop. 82,431,000), 137,699 sq mi (356,733 sq km). (represented here by American Maplan). Two twin-screw sheet lines are running undried PET at Faerch Plast A/S, a packaging firm in Holstebro. Denmark. The first line was installed in 2001 to produce up to 3300 lb/hr. The second arrived this year with capacity for 4400 lb/hr. These lines use 119-mm and 70-mm ZSK ZSK Zoological Society of Korea MegaCompounder Plus corotating Twin-screws from Coperion Werner & Pfleiderer (U.S. offices in Ramsey, N.J.). Faerch was the beta test A test of new or revised hardware or software that is performed by users at their facilities under normal operating conditions. Beta testing follows alpha testing. Vendors of packaged software often offer their customers the opportunity of beta testing new releases or versions, and the site for the Plus models, which were introduced commercially last year. They have extra-high torque and a special screw screw, simple machine consisting essentially of a solid cylinder, usually of metal, around which an inclined plane winds spirally, either clockwise or counterclockwise. design, both of which are said to be essential to maintaining very high I.V. Higher torque allows the line to run more slowly with the same output, increasing residence time under vacuum by about 20%.
