3 Theory of Operation

3-1 Control Knob

The Control Knob (see figure 1) is located on the right hand side of the laminator and is operated from the front of the machine.

The Control Knob can be operated by pushing it in approximately 6mm (1/4”) to the left. Once the knob has disengaged from the stop, it may be rotated forward or backward (clockwise or counter- clockwise, viewed from the right hand side of the unit).

Continue to rotate the knob until the desired nip setting corresponds with the indicator window at the base of the knob. Inside the window, the possible rotation directions are shown. Select the

value that corresponds to the thickness of the material you will be using with the machine. Releasing the knob so that it moves back to the right and clicks into place will set the rollers for use.

Select the next lower value in case there is no match for the thickness of the used substrate.

Internal functionality

See figure 2.

Inside the machine, a rod is mounted between the left- and right-hand framesheets. The knob is mounted on the rod; it allows axial movement, but no radial movement. The knob is provided with a pin (1), that falls in the indents (2) of a bracket (3). The same rod is provided with an eccentric (4) on either side of the machine. These eccentrics push or pull the arms (5), where the top roller is mounted in, upward or downward.

3-2 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 board being used. This is done so that anything passing between the rollers will receive the right amount of pressure and prevent damage to the rubber surface of the roller (and possibly the board).
