Loading Film Onto Mandrels; Film Tension - Banner American ValueLam 4500 Operating Instructions Manual

Loading Film onto Mandrels:

When the film is loaded properly the core gripper blade will prevent the film from turning on the
supply mandrel. With the gripper spring away from you, pull the core gripper blade toward you
and place the roll of film onto the mandrel. Turn the roll on the mandrel to lock the core gripper
blade into the cardboard film core.
Supply Mandrel Orientation:
The supply mandrels must be placed on the machine in the proper orientation to achieve film
tension. (Note the position of the core grippers in the illustration as viewed from the right hand
end).
Top Roll, Poly (adhesive) In
: With the gripper spring away from you, pull the core gripper
blade toward you and place the roll of film onto the mandrel so that the film unwinds towards
you from the bottom of the roll. Turn the roll on the mandrel to lock the core gripper blade into
the cardboard film core.
Bottom Roll, Poly (adhesive) In
: With the gripper spring towards you, push the core
gripper blade away from you and place the roll of film onto the mandrel so that the film unwinds
away from you from the bottom of the roll. Turn the roll on the mandrel to lock the core gripper
blade into the cardboard film core.
The core gripper blades on the top and bottom mandrels spring back in opposite directions.
The blade should spring back in the direction that the core will rotate when laminating. When
the film is loaded properly the core gripper blade will prevent the film from turning on the
mandrel. When using poly-in rolls the top roll of film should unwind from the bottom of the roll
and the bottom of the roll should also unwind from the bottom of the roll. With Poly-out rolls the
top roll will unwind from the top and the bottom roll will also unwind from the top of the roll.
Once the film is properly loaded onto the mandrels, replace the mandrels onto the laminator.

Film Tension:

Film tension must be set correctly to ensure good lamination quality. At each end of the film
supply roll mandrels there is a split Delrin® brake bushing. When the supply mandrel is placed
into the holders, the split of the brake bushing must be up. To adjust film tension, turn the
