The rewinder is fastened under the module rail
.
The dancer
1
pulls the paper web
4
from the
traction unit downwards. The winder mandrel
2
turns counterclockwise. The sprinf force of the
dancer is set with the dancer spring so that the force in the upper stop does not become too high.
With high labelling speed, the dancer roller must not impact the paper web. The direction of
action of the dancer
1
is the same as that of the spring force, i.e. if the dancer roller moves
downward, the motor must start to rotate. The direction of rotation of the motor is set with the
change-over switch
5
on the rear side of the rewinder cover.
For LEFTHAND MACHINES, the above information applies reversely!
ATTENTION:
The upper position of the dancer roller must be so that the paper web is
never fully stretched. Otherwise impacts on the traction unit may occur
which open the closure.
The angle of paper web around the dancer between winder mandrel and
traction unit must be an obtuse angle. See figure 6. In most cases a
stretched paper web will cause faults !
