The unit works as
a WINDER Drive as per the set tension on TENSION SET POT.
First select NORMAL
Start only un-winder
- Un-wind some material & STOP.
Now only run the
WINDER at very low speed & start winding the loose material.
Run the winder till
the material film is stretched gently & then STOP immediately
(by Run / Stop switch). This is the READY
position required to start the winder in TENSION
Now keeping the MAINS
SWITCH 'ON' - set the SPEED pot on 20% or 30% - Set
pot initially to 20% & change the switch to TENSION mode
OFF the power. - Finally
put the switch in RUN & keep the winder ready.
Start the Un-winder
at slow speed - The WINDER also has to run as soon as the
gets loosened. If it does not start,
increase the % of TENSION a little more, till it
Once WIDER starts
- it stretches the film & starts winding as per the set
Check the TENSION on the film/layer
near the winder & adjust it further if required.
Now slowly increase
the Un-winder speed to the required point. The winder
increases its speed proportionally - keeping the same TENSION
The SPEED SET pot in this mode has
no effect now.
The system will now
take care of the uniform TENSION throughout the process by
reducing its own speed proportionally with
the diameter of the film/layer on the bobbin/core.
At the end, put off
the Un-winder first - Put the switch in STOP mode & then
cut the material.
The winder tends to go to full speed if the film/layer is
cut / broken in-between. In
put off the system & re-start with the same procedure as
