Apparatus for processing flowable materials

摘要

The output from a first extruder (1) is fed to a second extruder (2) placed below it through a transfer zone (28). The end of the barrel (12) of at least one extruder is closed by a removable end cap (38) that includes passages to form the transfer zone. The end cap (38) can slide along rails under the action of an actuator (47) and can be housed in the body of the first extruder or in an intermediate housing (29).
