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.
