series EcoFlex/PowerFlex
automatic turret unwinders

The SML turret unwinder family consists of two different types of unwinders. The PowerFlex types are designed
for extra wide applications and high
speeds up to 600 m/min. Due to the
massive construction they can absorb
vibrations very effectively. The EcoFlex
unwinders give you a maximum of flexibility at a reasonable price level and
speeds up to 320 m/min.
Each unwinder has its own PLC-system with a touch screen operating
panel, which makes it easy to fit them
also into an existing production line.
Settings for different kind of materials
can be stored in recipes for quick and
unproblematic product changeovers.
Tension control is very sensitive due
to the speed control loop with an integrated ultra-light carbon fiber composite dancer roller.
The new bobbin has to be prepared
with double sided adhesive tape.

During the change over sequence the
new bobbin is synchronized to line
speed. The joining with the active web
and cross cutting will be done at production speed.
Chucking heads mounted on motorized moveable side frames make it
easy to work with different core widths.
The basic versions have one cutting
system for a roll change of a counter
clockwise rotating bobbin. Additionally
a second cutting system can be added
to give you the advantage of bi-directional unwinding.
The EcoFlex unwinders are built as a
modular construction system and due
to this they require a minimum of hall
space at a maximum of possible features. They can be equipped according
to your requirements.

A maximum unwinding diameter of
1500 mm helps you to enlarge roll
change sequences and to minimize roll
loading activities.
The optional constant gap unwinding roller gives you the advantage to
unwind aluminium foil at a minimum
thickness of down to 6,35µm.
If higher web tensions outside the unwinder are required, an additional take
off unit can be added at the outlet.
The motorized side frames in the turret
in combination with an optional edge
detecting support can be used as web
guiding unit.
For more simple applications SML can
also offer simple semi-automatic unwinders but SML can also offer specific
solutions especially developed for your
demands.
