series 900 winders
turret winders for rigid film and sheet
For rigid film roll stock to be sold
off the line, SML recommends the
series 900 winders. Built for frequent
roll change, they are operated with a
central drive for gap winding mode and
can be used with both 3” and 6” pneumatic
winding shafts. Optionally, the
SML’s series 900 winders can be fitted
with friction shafts and dual direction
winding. SML‘s series 900 turret winders
work with an accumulator up front
to allow for manual start-up of the new
roll while the web is stopped.
This concept makes the series 900
winders easy and safe to operate. The
edge trimming and slitting station is
placed between the accumulator and
the winder. Guide rollers or mechanical
guides redirect the trims to the

edge trim granulator, situated next to
the extrusion line. The film enters the
winder through a take-off that includes
the cross-cutting device.
Once the required roll length or outside
diameter is reached and the new, prepared
core is in position, the cross cut
is actuated automatically, and the accumulator
takes in the film produced.
For sensitive films, the cross cut can
also be done manually by the operator.
From the take-off a set length of film is
released so the operator can manually
attach the film to the new core in place.
The shaft is then accelerated, and the
film, stored in the accumulator, is released.
At the same time, the photocell
controlled gap winding roller arrangement
is lowered to its working position,
and the winder is back in operation.

Depending on customer requirements,
different accumulators are available:
- The driven accumulator working
from bottom to top position, where
movement and web tension are generated
by a servomotor. This system
is suitable for gauges as low as
150 µm and line speeds up to
70 m/min.
- With gravity accumulator working
from top to bottom position where
web tension is generated by gravity.
This system is available with limited
width and winding speed.
