Rollepaal

Twin Screw
Extruders

Rollepaal offers a wide range of high
capacity PVC extruders with screw
lengths from 28D up to 33D, depending
on application and output. The extruders
have a wide processing window for
reliable pipe production at a low reject
rate. The robust design and controls with
proprietary software gives operators the
opportunity to reach for higher
productivity at each stage of the pipe
extrusion process.

Benefits of our extruders:
Max. outputs from - kg h
Smooth pipe due to screw geometry for a
longer effective screw length
Direct Tor ue ontrol with a highly constant
screw rpm
Energy savings
Internal screw cooling based on heat pipe
system
Air-cooled barrel for a more gradual cooling
High efficient direct A drive with direct tor ue
control

The screw geometry is developed for a large
processing window and in combination with
the direct drive concept it provides a higher
quality homogeneous melt. The innovative and
technological features of the INAVEX extruders
result in energy savings.

Mastering the process is the best guarantee to
stay ahead of competition. INAVEX extruders
make it possible.

Multilayer
Die Heads

A revolutionary idea started the development
of the Rollepaal Multilayer Die heads (RMD).
The technology is based on the principle of
symmetrical branching of the melt to feed the
layers. Symmetry in melt feed guarantees the
best layer distribution, because all ow lines
have equal length.

The layer distribution is independent of melt Features of our RMD series:

Haul Offs

Rollepaal offers an excellent program of
state of the art haul offs, with state of the
art motor control technology from 12 mm
to 800 mm. The program is designed for
accuracy, socketing and ease of use during
start-up & production. The wide range of
Rollepaal haul offs offer you maximum
flexibility. The DHO is available in 2, 3, 4, 6 or
8 tracks.

Frame
The steel frame has a robust rectangular shape for high
rigidity and is completely closed-in for maximum safety.
All electrical equipment including the control panel is
located on the side panel of the frame. A pipe guide roller
is placed on the inlet side of the haul o . On the four
lower corners of the frame a height adjustment device is
mounted.
Tracks
The track is an endless roller of chain covered with
pro led, wear resistant, rubber blocks, giving maximum
grip without damaging the pipe. The lower tracks can
be adjusted to the pipe diameter by an electrical driven
height adjustment device. The upper tracks are being
pressed onto the pipe by pneumatic cylinders. A separate
pressure regulator can be placed on the in- and outlet
side of the pipe.

The DHO range is suitable for continuously pulling of
thermoplastic pipes with the help of haul-off tracks
controlled by separate AC motors. A very accurate and
constant hauling speed is obtained via the servo controller
thus maintaining a uniform speed for each track, important
to prevent pipe deformation.

Material is the largest cost component
(around 80%) in the manufacturing
of plastic pipe. This fact makes it
worthwhile to reduce overweight and/or

the pipe in the required speci cations.
Rollepaal o ers several types of cost

of the pipe during production. These
solutions are compatible with all
existing brands of equipment.
