When the belt is stopped following precautions are essential,
in order to obtain the maximum service life:
A.- The belt must be stopped with the operational temperature working.
B.- The belt tension must be reduced to the minimum needed
to engage the drive sprockets properly or adjunted according
to the manufacture´s documentation. This applies in particular
for high temperature ovens, which are equipped with a counterbalance
or air cylinders fot the belt take-up at the extreme unloading
end. The high counter tension conveys along the belt in such
a way that the tension in the heated area may be bigger than
where the belt carries the load.
C.- A high temperature belt must be maintained in motion,
if stopped it may weld to the support of the oven and cause
serious damage when restarted.
D.- Regular tests regarding the direction of the belt must
be carried out without load, as the changes of temperature
induce quite often to changes in the run.
In this chapter "BELT STOP", stop is understood without any load on the belt.
