Abstract
A production line (200) for performing multi-pass mixing sequences of rubber mixtures has at least one first mixing line (200A) that produces a masterbatch and at least one second line (200B) that performs a final mixing process during a final pass of a multi-pass rubber mixing sequence. A mixing process produces a variety of rubber mixtures in a production line of the type disclosed.

-10. (canceled)
A rubber mixture production line (200) for performing multi-pass mixing sequences, the production line (200) comprising:
- at least a first mixing line (200A) comprising:
- at least one internal mixer (MI) that performs a masterbatch manufacturing process;
- a hot mixing line (202) disposed downstream of the internal mixer (MI) and comprising at least one twin-screw mixing machine (BXC) that performs a mixing process of the rubber mixture exiting the internal mixer (MI);
- a transfer belt installation (TT) disposed downstream of the hot mixing line (202) for controlling a temperature and an addition of water in a rubber mixture exiting the hot mixing line (202);
- a batch-off installation (BO) disposed downstream of the transfer belt installation (TT) for performing an anti-sticking and cooling process of the rubber mixture exiting the transfer belt installation (TT);
- and
- an end-of-line installation (FL) disposed downstream of the batch-off installation (BO) that performs one or more end-of-line processes on the rubber mixture;
- and
- at least one second mixing line (200B) comprising:
- a twin-screw mixing machine (B1) that performs a mixing process of the rubber mixture exiting the first line (200A);
- a transfer belt installation (TT′) disposed downstream of the twin-screw mixing machine (B1) for controlling a temperature and an addition of water in a rubber mixture exiting the twin-screw mixing machine (B1);
- a cold mixing line (204) disposed downstream of the transfer belt installation (TT′) and comprising at least one twin-screw mixing machine (BXF) that performs a mixing process of the rubber mixture exiting the transfer belt installation (TT′);
- a batch-off installation (BO′) disposed downstream of the cold mixing line (204) that performs an anti-sticking and cooling process of the rubber mixture leaving the cold mixing line;
- and
- an end-of-line installation (FL′) disposed downstream of the batch-off installation (BO) that performs one or more end-of-line processes of the rubber mixture,
- wherein the second line (200B) performs a final mixing process during a last pass of a multi-pass rubber mixing sequence.
