New AutoGrip® Electro-Mechanical Clamp Starlinger rounds off portfolio with new
from Graham Engineering
raham Engineering Corporation has designed a
G New Auto Grip® Electro-Mechanical Clamp. The
new extrusion clamp with electro-mechanical
actuation is safer and simpler to operate than manual
devices and provides more repeatable clamping forces
also reducing the risks of manual changeover. The Auto
Grip® power clamp reduces downtime in installations
with frequent screw, breaker plate, or tooling changes.
It reduces the risk of injury or burns involved in
manually releasing and tightening clamps during
changeovers. The torque required in manual systems
to sufficiently seal the clamp assembly is particularly
dangerous with large extruder sizes. In addition, the
manual clamps are typically heated to temperatures of
greater than 400 °F (200 °C), increasing the risk of
injury with traditional manual systems. The Auto Grip
clamp is remotely controlled by a two-hand
pushbutton controller for user safety and convenience.
The drive motor and gear box are mounted above the
clamp, protecting them from melt residue and making
them easy to access for maintenance. “We have
engineered the Auto Grip system with simplicity and
safety in mind,” said Michael Duff, Vice President of
Sales and Service for Graham Engineering Corporation.
“While manual clamps are difficult to operate and
inherently dangerous, this new automatic system from
Graham Engineering speeds up changeovers and is easy
to maintain.” The Auto Grip power clamp is available
for extruder sizes of 3.5 in. (90 mm) through 6 in. (150
mm). In addition to applications involving new
extruders, it can be retrofitted on many existing
installations.

circular loom RX 8.1
tarlinger has introduced its new circular loom RX
S 8.1 The RX circular loom series is now extended
with the RX 8.1, a circular loom that is particularly
suited to the production of lightweight fabrics for 1-
loop FIBCs, tarpaulins as well as geo- and agrotextiles
made of PP, HDPE, and PET. In combination with the RX
6.0, RX 6.1, and RX 8.2, Starlinger Taicang now offers
the ideal circular loom for every fabric width. The new
Starlinger circular loom RX 8.1 produces fabric with a
width of 1,200 – 1,700 mm, which is an ideal match for
1-loop FIBCs, tarpaulin fabrics as well as geo- and
agrotextiles.
The model completes the RX series, which now covers
every working width between 300 and 2,250 mm. Like
all models of the RX series, the RX 8.1 is equipped with
numerous technological advantages. Due to its special
reed and shuttle design, the machine does not have
any sliding parts that would require lubrication, and
thus leaves no traces of oil on the fabric. This property
allows for the optimal adherence of the coating to the
fabric and eliminates concerns regarding the use of
the fabric in food applications. Moreover, the RX 8.1
produces fabric of highest quality at lowest
production cost per square meter, as the production
speed of 800 picks/minute is high while the number of
warp breaks is low. Other advantages are the
machine's user-friendliness, the energy-saving motors
as well as a low noise level.
