Unwind Brakes; Roller Nip Settings; Image Guide Storage Place - SEAL 54 EL-1 Instruction Manual

4.2.3 Unwind brakes

Tighten the unwind brake so that it applies sufficient tension to laminate. Turning the knurled brake
collar in a counter-clockwise direction increases the breaking tension applied on the laminate. Turning
the collar clockwise decreases the tension. The best setting for the brake tension is determined by the
materials you are using and is learned through experience.

4.2.4 Roller nip settings

Whenever you mount onto a board, etc., it is important to adjust the rollers to create a gap nearly
equal to the thickness of the substrate being used. This is done so that anything passing between the
rollers will receive the right amount of pressure to prevent damage to the substrate being mounted
(and possibly the rollers).
Turning the Nip Hand Wheel counterclockwise (CCW) lowers the top roller, and clockwise (CW)
raises the top roller.
How to set the nip:
Determine the thickness of the substrate that you will use for mounting. Pre-set the nip height by
turning Nip Hand Wheel CW until the nip height indicator is above the board thickness.
Insert the front edge of the substrate into the nip by hand. Lower the top roller by turning the Nip Hand
Wheel CCW until top roller contacts the substrate with enough pressure that the substrate cannot be
moved side to side. Use reverse button to remove substrate from nip if needed.
To run films, rotate the nip hand wheel CCW until the nip is fully closed then continue until the Nip
Hand Wheel turns freely.

4.2.5 Image guide storage place

When not in use, the Image Guide can be stored on the upper cross brace or alternately on the lower
cross brace(figure 9). Note: Image Guide is optional on some models.
