The air blast of the air tube 27 may be
regulated through the chokes 28 and 29. In
order to achieve an exact sheet separation
it is necessary that the first 10-15 top sheets
of the shingled pile are properly ventilated.
In addition to the air tube 27 a side blower 30
may be used. The air support may be regulated
through the chokes 31. This side blower may
be adjusted in the longitudinal as well as in
the transversal direction of the feeder through
the element 32. The balance of the blower
should be adjusted through the weight 33 to
such an extent that the blower is slightly
touching the sheet. A dip of the blower may
be avoided after adjusting the knurled screw 34.
This will be achieved a even ventilation.
For a controlled move of the sheets to the
alignment table smoother use bars 65 and
two spring steel smoothers 66 beyond the
air tube and smoother bar 64 into the
direction of the feeder are used. These bars
also creates a suction effect for better sheet
control.
