Strip Speed
This parameter sets the speed at which the nozzle travels down the length of the fiber. A
faster strip speed will essentially strip faster if enough heat transfer is present. The heat
transfer is composed of temperature and time because flow is considered a fixed setting from
the factory. Exposure time is a function of the strip speed. Each small section of the fiber
receives some specific heating time depending on the speed of the nozzle. For example, the
same strip results of high strength and clean fiber could be achieved using either high speed
high temperature, or low speed low temperature. Both cases result in the same heat transfer
to the fiber. On the fixed nozzle version, the heat transfer is controlled by temperature and
time directly.
Ramp Time
This parameter is the time allowed for the heater to ramp to strip speed.
Air Post Delay
Just as the pre-delay is the time the heater waits to translate after the air flow starts, the post-
delay is the time the heater flow stays on after the translation has stopped. As with the pre-
delay, a longer post-delay will generate a sharper transition but strength degrades more with
time.
Vacuum Post Delay
The vacuum post delay is similar to the hot-air delay at the start of the stripping process. This
parameter controls when the vacuum is turned off after the heater flow has been turned off. A
negative value is not allowed. The common value is 1s to ensure that the harmful gases are
all removed and filtered using the vacuum.
