Feeding Technique; Side By Side Laminating - usi CRL 40 Instruction Manual

9.3 Feeding Techniques
Ensure the article to be laminated is flat and free of curl or creases (See Section 12.1, De-curling,
Page 24). Lay the article flat on the feed table and with your fingers slightly stretch it to the sides to
flatten out any creases or curl on the leading edge. Move the article towards the laminating nip at
approximately the same speed at which the film is passing over the heat shoes - not any faster.
Forcing the items into the laminator results in insufficient heat on the leading edge of the item and
may result in poor lamination of the front edge, especially the front corners (See Sections 14.4, Page
28).
Once the nip "catches" the item it will be drawn forward by the rollers. Retain a slight outward and
firm backward pressure on each edge of the item to avoid any creasing. Large lightweight posters
may require substantial pressure. Hold the item for as long as possible to prevent the trailing edge
from buckling.

CAUTION :
Always keep your fingers clear of the laminating nip, ensure that no loose clothing e.g. ties
come close to the laminating nip.
9.4 Side By Side Lamination
When wide lamfilm is loaded you may wish to laminate items side by side. Very useful for small
numbers of odd sized items. This is not a recommended practice as it is wasteful of expensive film.
The best utilisation of film will always be achieved by using narrower film and feeding items
accurately one up. One up feeding substantially reduces the time taken in trimming.
Should you choose to run two up it may often be difficult to achieve a satisfactory side seal between
the two items. Thicker items in particular will not seal in the middle area as the laminating rollers
are unable to exert sufficient down-pressure between the two items. The limitation of the machine
must be considered and it is sometimes necessary to change to a small film width and run the items
one across.
