2.3 Transportation system - ventilation
The sheet transportation is controlled by
the feeler tongue 20 and a inductive switch 38.
If no sheets are at the tongue and if the end
of this tongue 39 is placed at the inductive
switch 38 the feeder will run approximately
2,0 m/min in rapid speed, if sheet infeed 6
is activated. If the feeler tongue 42 leaves the
sensor 38, caused by the sheets arrive], the
speed will reduce to ca. 0,3 m/min The sheet
transportation will stop if the distance between
the end of the feeler tongue and the sensor 43
is approximately 8 mm.
The feeler tongue 20 may be adjusted through
two buttons at feeder operator side in a horizontal
40 and vertical 41 position.
Button 40 sets the tongue forwards and
backwards. Button 41 sets the tongue
upwards and downwards.
Tongue 20 should be moved forwards if sheets
need to be more ventilated 44 but if a few
sheets should be ventilated 45, move the
tongue 20 backwards.
If the sheets tend to roll down you should set
the tongue downwards 46. If sheets tend to
roll up then you should set the tongue
upwards 47.
If the sheets tend to roll up you may affix
and additional smoother bar 48 beside the
suction Meet onto the tie-bar. The plate
spring 50 with the knurled screw 49 enables
you to smooth sheets which tend to push upwards.
Between the lower transportation tape 51 and
the feeler tongue 20 rests an infeed plate 52
