THREADING the LAMINATOR
Although this machine can be threaded cold, most operators feel it’s easier to thread while it is
warming up or already hot. The Professor 27 was designed to allow the operator to safely and
easily thread the laminator while it is hot
1.
Remove the supply roll mandrels. The supply roll mandrels are now ready to accept loading
of the film rolls, wound with the polyester (shiny) side out. The tension control knobs should
be positioned on the right
2.
Slide a roll of film onto the top supply roll mandrel. Make sure the dull side of the film is
facing up and the shiny side is facing the heat rollers during the threading.
3.
With the roll of laminate centered on the mandrel, place it in the top bracket. Place the left
side of the shaft in its slot first, then place the right side of the shaft in its slot, turning it as
needed to align the hexagon bushings with their respective slot(s).
5.
Review the threading diagram. Run the film from the top mandrel under the idler bar and
drape it across the top heat roller.
Remember, the shiny side of the film must always go
against the roller.
The dull (adhesive) side must face away from the roller. With the top
roll of film centered on the mandrel and the shiny side facing down and draped over the top
heat roller, you are now ready to load the bottom supply roll mandrel.
6.
Load the bottom roll of film onto the mandrel in the same manner as the top roll. Remember,
the shiny side of the film must always go against the roller. The dull (adhesive) side must
face away from the roller. Make sure the two rolls are aligned with each other before going
to the next step. Now drape the film from the bottom roll against the film from the top roll
on the top roller. If the laminator is hot, the exposed adhesive on the top web will hold the
bottom web and make it easy to stick the two webs together. If you are threading the
machine while it is cold, use tape to stick the bottom web against the top web.
7.
With both rolls threaded and installed in their respective brackets, unwind the top and bottom
supply rolls about a half-turn each. This will provide enough slack in the web to allow the
feed tray to close easily. Remember, the bottom idler bar is attached to the feed tray. If
there’s no slack in the web, the feed tray will be difficult to close.
8.
Swing the feed tray into it’s closed position.
9.
Swing the safety shield down into the laminating position. Lock the swing away top cover
into position using the lock lever located in the center of the cover .
The machine will not
operate without the safety shield ( and integral safety switch ) in the down and locked
position
. NOTE: the swing away feed tray is held in it’s closed position by the upper swing
away cover. The feed tray must be closed before the top cover or the laminator will not
function properly. Once the top cover is properly locked, close the laminating rollers with the
large knob on the right side of the unit. With the film draped over the two heat rollers, push
one edge of the threading card into the roller nip.
