Method For Tacking New Film to Pre-existing Film
The following describes a method for loading film whereby the pre-existing
film present on the heat rollers may be used in place of the threading card to
draw the new film through the laminator. The adhesive of the pre-existing
film must be tacky or liquefied. Leading edges of the new film will be
overlapped onto pre-existing film. The tacky adhesive of the old film will
adhere to the leading edges of the new film. The pre-existing film and the
new film will be simultaneously drawn through the laminator.
1. Position the ON/STANDBY switch to the "Standby" setting. Remove feed
table.
2. Cut remaining top and bottom film webs between supply rolls and heat
rollers.
3. Raise shield to full upright position.
4. Do not allow adhesive side of pre-existing film to contact heat or pull
rollers. Liquefied or tacky adhesive deposited on heat or pull rollers will
require the rollers to be cleaned per the section entitled Caring for the
GBC4250 Laminator.
5. Remove feed table and bottom film guide (see figure 6).
6. Remove bottom supply roll from laminator and remove film roll core from
supply roll shaft. Observe that both core clips are still located on the supply
roll shaft. Check removed core if either core clip is missing.
7. Slide new film roll onto supply roll shaft. Compare film roll orientation of
newly installed roll with threading diagram (figure 4) or threading label
located on laminator.
