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.
