Preventing Wrap Around - usi CRL 40 Instruction Manual

9.10 Preventing Wrap-Around
When laminating with massive imbalance in film tension or with thinner gauge films, there can be a
tendency for the finished laminate web to wind back up as it exits the rear pull rollers. This may
happen to the degree that it could curl over and back onto itself and wrap around the rear pull rollers.
To minimise the occurrence of wrap-around make sure the laminated web does not curl back on
itself, especially when tensioning newly loaded film.
If a wrap-around does occur, you can easily correct it by reversing the direction of the rubber
rollers, permitting the laminator to release the plastic from the rolls.
(a) Remove the feed tray.
(b) Cut the plastic web on the top and bottom just in front of the idler bars.
(c) Disengage the plastic from the heat shoes and grip the two loose ends firmly
together.
(d) Turn the motor control switch to reverse.
(e) Pull the plastic film firmly as it exits the nip rollers ensuring that it does not wrap-
around the front nip rollers.
CAUTION :
Never use a knife or other sharp object to cut the plastic film with a wrap around. Any damage to
the expensive silicone rubber rollers will leave a permanent impression on your lamination.
