4.1 Setting of foldrollers
In order to achieve the required setting of
the foldrollers you should press the lever
3 at caliper setting element 2 and insert
a paper strip of the material to be
processed between the pressure plate 5
and pressure bar 6.
Thereafter, turn the handwheel of the
machine and, in doing so, check whether
the paper strip goes through the
foldrollers, then adjust the knurled screw
1 to achieve an even pressure of
foldrollers to paper strip at operators and
operators opposite side. When you turn
the knurled screw 1 clockwise, the
pressure on the foldrollers becomes less,
if you turn the knurled screw counter-
clockwise, the pressure on the foldrollers
has increased. After this basic setting
reset the adjusting ring 4 to
0-position, in order to enable a quick
readjustment of foldrollers into their
original position. A slight tightening of
locking screw 7 will secure it against
unintended twisting. For setting of slitter
shafts proceed in the same manner.
Depending on the kind of fold you may
now insert the paper strip to achieve the
desired paper gauge between the
pressure plate 5 and the pressure bar 6.
You will find instructions to set the most
commonly parallel folds on pages
D1 - D3.
A scheme of foldrollers 8 indicates which
elements belong to the individual pair of
foldrollers. This scheme is also fitted as
a diagram on the side frame of the
machine.
