                Four-shaft Gear Concept

                An innovative gear concept ensures safe distribution of
                a most powerful driving torque. The novel solution re-
                duces the torque load on the individual pair of pinions
                to merely a quarter of the all driving torque.

argos extruders are designed for productivity on the basis of high output capacity and
unique processing latitude. The processing unit with an effective L/D ratio of 28:1 keeps
stress on the raw material at a minimum by efficient heat transfer guaranteed by an optimal
residence time spectrum and large internal surfaces.

argos extruders are designed for utmost mechanical reliability. An innovative four-shaft
concept is used for the distributor drive and enables to work with high torque at low screw
speed. Overheating is safely avoided so that top product quality is consistently ensured.
Additional safety is built in by the driver’s large centre distances.

                       With the high L/D ratio, more than tripling of the residence time in the pre-heating zones
                       is achieved - greatly improving the processing performance.

Drive and auxiliary Units

AC- or DC-motors are used to drive the argos extru-
ders. The motors are mounted alongside the distribu-
tion gearbox to save space.
The argos 72-28D has the main motor flange moun-
ted directly to the reduction gearbox.
All other extruder drives are mounted on the extruder
The degassing system and the optional external screw
temperature control system are positioned directly be-
low the barrel.

argos extruders use modular design concepts. De-
pending on the application, the machines feature an
L/D ration of 23:1, 26:1 or 28:1 and purpose-tailored
motor power corresponding with the particular reduc-
tion gear ratio and screw speed maximum.
The control cabinet with the rotating operating termi-
nal is mounted on the left side of the extruders. The
standard screw centre height is 1100 mm. Special
versions with non-standard extrusion height or stand-
alone control cabinet are offered upon request.          argos AC-drive units

Pipe (R), profile (P) and sheet (PL) versions of the argos extruders are available. Motor power,
screw speed and the electrics of the different types are tuned to the specific requirements of
the various product groups. High motor power is only used where actually required.

argos R for Pipe Extrusion

Pipe version with high motor power and screw speed.
Three-phase heating zones are provided for all custo-
mary pipe toolings. Main motor synchronised with
haul-off unit. Suited for automated production by ad-
dition of modules including gravimetric feed control,
wall thickness measurement, haul-off control and
automatic centering of the pipe.

argos PL for Sheet Extrusion

Special size 112 or 132 sheet versions with screw
speed and driving power corresponding to the pipe
versions. Heating and cooling of all barrel zones inclu-
sive of zone 1 is provided. Equipped with active oil cir-
culation screw core temperature control. Two-stage
vacuum pump with enhanced capacity. Stainless steel
screws with special mixing section guaranteeing com-
plete absence of flow lines. Pre-installed sheet die
electrics and synchronisation with downstream line.

argos P for Profile Extrusion

Profile versions with down-stepped screw speed des-
irable in particular for impact modified formulations.
While the motor power is lower for better economy of
operation, the screw torque of the pipe versions is
maintained. One-phase tooling heating zones bring
about additional energy savings. Excellent processing
capability for the most diverse formulations irrespec-
tive of variations in the raw material properties. Re-
placement of lead by calcium/zinc stabilisation pre-
sents no problems.

choose between a variety of feeding variants. Direct gate-controlled feeding from the full
hopper or a metering unit can be used. Additionally special vertical dosing units and
crammer feeders for poor flowing formulations are available.

      Tele Service

      Tele-servicing and tele-maintenance of EXcPRO-XP
      controls is possible via direct modem connections, ca-
      ble links (parallel or serial data communication), LAN
      networks or Internet connections. The modem nee-
      ded and the Internet account are shipped as standard
      with every CET-extruder featuring EXcPRO-XP con-
      trol. Tele-servicing permits not only data copying and
      display - it also provides genuine remote operation,
      including control/process diagnosis. Consequently,
      program modifications, such as activation or adapta-
      tion, can be made easily.

Tele-servicing via the Internet with the possibility of simultaneous access
by several engineers offers unique advantages.
For example, a process engineer may carry out a process diagnosis through the
remote control functions provided while a software specialist, who may even be
located in a different place, uses programming tools to diagnose and perhaps
modify the visualisation/PLC software directly.
