Ledco HD-25, Инструкция по эксплуатации

Страница: 41 / 52

Make sure the film is threaded properly. The most frequent operator error is
threading the film under the bottom stabilizer bar instead of under the bottom
idler bar. The threaded film should not touch the bottom stabilizer bar. When
the bottom web of film is threaded around the stabilizer bar instead of the
idler bar the film will tend to wrinkle and often will not adhere. The top side of
the item will not be affected.
PROBLEM: Film gets wrapped around the pull rollers.
SOLUTION: While threading the film cold the loose ends of the unlaminated
web are particularly susceptible to “wrap-around”. To minimize this pull the
threading card after it emerges from the pull rollers until the film clears the
exit table. Use caution when first starting to laminate being careful that the
thin, unlaminated web does not get caught in pull rollers or laminating rollers.
If a “wrap-around” does occur while the laminator is cold you can easily
correct it by reversing the direction of the rubber rollers. This permits the
laminator to release the film from the rollers.
PROBLEM: Film gets wrapped around the laminating rollers while the
machine is hot.
SOLUTION : Leave the heat on so that the adhesive does not harden and
follow the following steps.
WARNING: Be very careful not to touch the heat shoes when the
machine is hot.
MISE EN GARDE: Ne pas toucher les sabots chauffants lorsque la
machine est chaude.
ADVERTENCIA: No toque las zapatas calefactoras cuando la máquina
está caliente

1. Remove the feed tray.
2. Carefully cut the film on the top and bottom just in front of the idler bars.
3. Loosen the film from the heat shoes and grip the two loose ends, holding
them together.
4. Turn the drive switch to the reverse position.
5. Turn on the drive at a very low speed and allow the laminator to back out
the film that is wrapped around the rolls. Pull the film off the roller.
WARNING: Keeping the machine in reverse may cause a reverse wrap-
around if the film is not getting pulled off the roller. You may need to
pull on the film with a lot of force while stopping and starting the drive.
