4.4 ADJUSTING THE TENSION AND CENTRING OF THE CONVEYOR BELTS
To ensure the best performance and results, the tension of both conveyor belts must be properly regulated so
that the dough moves smoothly and uniformly as it passes through the various rolling stages. Even small
variations in the speed of one or both belts during the rolling process can subject the dough to abnormal stress
and cause it to tear. This decreases the quality of the dough sheet or can even make it impossible to produce it.
The thinner the sheet, the more evident this problem is.
The tension of the conveyor belts should be checked and adjusted whenever you notice that they move
unevenly.
With reference to Figure 32, using an open-end spanner, turn the nuts ref. 1 on each side of the bench in order
to move the roller ref. 2 forwards/backwards via the threaded rods ref. 3. Tension the conveyor belts as much as
necessary (or slightly more) so that their speed is uniform both when empty and unloaded. Excessive tension
would not provide any advantage but could cause rapid and abnormal wear.
Depending on the destination or the contractual agreements, the machine may be fitted with plates ref. 4
fastened with screws ref. 5. These have to be removed in order to carry out adjustments.
Once adjustments have been completed, replace the plates ref. 4 on both sides and fasten them using the
screws ref. 5.
The same devices are also used to adjust the centring of the belt on the bench. With respect to this, it should be
remembered that when in motion, a conveyor belt tends to move towards the side that is less taught. It is
therefore very important that the tension is the same on both sides of the belt.
The tension and/or centring of the belts has to be carried out while the machine is in operation. Only in this way
is it possible to see the effect of any adjustments.
WARNING! Do not place your hands in the zone in which the roller and belt converge to avoid the risk of
trapping and dragging. Also, hold the open-end spanner firmly. If it were to fall onto the belt while it is in
motion, it could cause serious damage to the machine.
