3.1.5 Despool Brake Adjustment
The despool speed is controlled at the Despool Drive. At faster production speeds, the
despool speed needs to be decreased to avoid tangling of the backer material. If there is
too much tension which can occur if the despool drive is rotating too slowly, the backer
material will tear. If there is not enough tension which can occur when the despool drive
is allowed to run freely, the backer material can become tangled. The despool speed can
be adjusted by turning the Brake Adjustment Knob as shown in
Figure 3-5. A clockwise
rotation of the knob will decrease its speed while a counter-clockwise rotation will
increase speed.
