for calendering lines
Series W400 / W500 jumbo roll winders can produce
rolls with diameters of up to 2,000mm, which minimises
the downtimes caused by roll changes in inhouse
thermoforming applications.
Each winder consists of two A-frame winding trolleys
with 3- or 6-inch pneumatic winding shafts. The
twin-trolley principle means that while one trolley is
in active operation, the other is on stand-by for a
roll change.

the control panel and the winding speed accelerated
thus releasing the lm stored in the accumulator.
Series W600 cantilever winders operate according to
the same principles as mentioned above, although xed
winding stations with cantilever shafts are used instead
of A-frame winding trolleys. This allows simple roll removal
using a manually operated forklift, which again eases the
burden on the machine operators.
Series W400 winders

In the case of inline, part-bobbin slitting, a maximum
of three webs can be produced. The winders are
arranged in sequence and combined with one
upstream accumulator. This is activated during
bobbin changes and takes up the lm, while all the
subsequent take-off units and winders are stopped.
As a result of their design, the winders are easy and
safe to operate. Pneumatically actuated cross cutting
stations are located above each of the winders and
these cut and remove the web automatically in
accordance with the pre-set length. The operator
merely has to attach the sheet onto a new core and
then presses a foot pedal so that a few layers of sheet
are wound on. The winder can then be restarted from
