3.3.1.2 Blow-Air System
The blow-air system performs s everal functions.
First, it separates the sheets so the effect of the
vacuum bleeding through the paper is less critical.
Also, with the second sheet separated from the
first sheet, it allows air to get in between the sheets
when the top sheet is removed from the stack. This
prevents the first sheet from sucking up the second
sheet. Another function of the blow--air is to lift the
top few sheets until the top sheet is up against the
sheet separator finger. This establishes a uniform
height for the top sheet so that it will be in the
proper position when the nozzles come down for
the pick--up.
The feeder is equipped with four blow nozzles.
Two of these blow in from the edges of the stack
and two blow in from the front of the stack.

3.3.1.3 Vacuum Nozzle Set--Up
It is necessary to use different quantities of
vacuum nozzles to run different types of
production. Vacuum nozzles may have to be
moved horizontally to accommodate different sheet
sizes.
Use two nozzles (one per block) for 4200
laminated and cut tabs per hour.
Note ! It is not possible to run 5,000 tab cut
and laminated sheets per hour.
