Flying
Splicer

"Flying
Splice" - As the main feeding roll nears
its end, the roll stand is rotated to
bring the next full roll of paper into
running position. This is done with the
press running at full or operating speed.
Double-sided tape is applied to the leading
edge of the new roll. The new roll is
moved into contact with the running roll
of paper. The taped edge of the full roll
is pressed against and immediately adheres
to the running roll. Paper from the depleted
roll is cut off and the roll brought to
a stop. The old core is taken off and
a new roll is then place on the backstand.
As mentioned earlier, this type of splicing
system is usually used on wide offset
and gravure presses greater than "38."
Zero
Speed Splicer

"Zero
Speed Paster (Splicer)" - This splicer
differs from the splicer above in that
the old and new roll stop momentarily
during the splicing process while the
web press continues to run. To start the
splicing process a new roll is positioned
and taped. When the feeding roll nears
its end, the paster unit festoon draws
out considerable slack in the running
web which allows both the new and old
roll to stop momentarily. To make the
splice both the old web and new web make
contact momentarily and the tape is contacted
from the new roll to the old running roll.
The web is cut from the old roll an the
new roll allowed to come up to web speed.
These operations are performed before
the slack in the festoon is absorbed or
taken up.
