Claims (8)

1. Многоэкструзионное устройство, отличающееся тем, что два вращающихся в одном направлении двухшнековых экструдера для смешивания экструдируемого материала и один вращающийся во встречном направлении двухшнековый экструдер в качестве органа создания давления соединены между собой по потоку.
2. Устройство по п.1, отличающееся тем, что два вращающихся в одном направлении двухшнековых экструдера и вращающийся во встречном направлении двухшнековый экструдер расположены друг за другом.
3. Устройство по п.1, отличающееся тем, что два вращающихся в одном направлении двухшнековых экструдера расположены параллельно друг другу, причем шнековые пары могут иметь одинаковые или встречные направления вращения, а за обоими вращающимися в одном направлении двухшнековыми экструдерами включен служащий для создания давления, вращающийся во встречном направлении двухшнековый экструдер.
4. Устройство по п.3, отличающееся тем, что соответственно один из имеющих разные направления вращения шнековых валов каждой шнековой пары удлинен и переходит в шнековый вал подключенного двухшнекового экструдера так, что его шнековые валы вращаются тогда во встречном направлении.
5. Устройство по п.4, отличающееся тем, что предусмотрен привод, содержащий четыре выходных вала, которые соединены со шнековыми валами вращающихся в одном направлении двухшнековых экструдеров.
6. Устройство по п.4, отличающееся тем, что предусмотрен привод с шестью выходными валами, так что шнековые валы могут приводиться порознь.
7. Устройство по п.3, отличающееся тем, что соответственно на конце шнековых валов расположены зубчатые колеса, которые находятся в зацеплении между собой таким образом, что шнековые валы вращающихся в одном направлении двухшнековых экструдеров приводят шнековые валы вращающегося во встречном направлении двухшнекового экструдера.
8. Устройство по п.7, отличающееся тем, что предусмотрено в общей сложности шесть зубчатых колес, которые находятся в зацеплении между собой таким образом, что соответственно зубчатые колеса одного двухшнекового экструдера находятся в зацеплении с зубчатым колесом на шнековом валу последующего, вращающегося во встречном направлении двухшнекового экструдера, и они находятся в зацеплении между собой.
