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.
