Application No. 08/266,558
Kalisiak discloses a system and method for pressure
sealing business forms to provide for maximum utilization of
floor space and ease of control by an operator. As shown in
Figure 1, first and second pressure sealing devices 11, 12,
each having upper and lower sets of rollers forming nips for
sealing business forms only along strips of pressure sensitive
adhesive, are mounted one above the other. A common drive is
provided for the drive rollers of each set, for each sealing
device. Tape conveyors
assist in conveying the forms through the first sealer, around
a horizontal axis large diameter drum, and from the large
diameter drum through the second sealer, the forms moving in
the opposite
direction to the one they moved in through the first sealer
when going through the second sealer. A rotator 14 is
provided between the drum and the second sealer for changing
the orientation of the forms about 90°. The forms are fed to
the first sealer by an infeed conveyor/deshingler 15, and are
removed from the second sealer by an outfeed conveyor/stacker
16.
