(57) An automatic method for controlling the working speed of a weaving loom, for the
purpose of optimising the productivity thereof, comprises the steps of: starting the
loom at the speed Viniz equal to a standard working speed; detecting the overall number
of stops NF1 in a first period of time t1, and determining the value of BF1 and RM1
by the formulas:
in subsequent periods of time t2, t3, tn detecting in a similar way the overall number
of stops NF in any period, calculating the values of BF and RM of the different periods;
at the end of each period t after the first one, comparing the value RMn of period
tn with a reference value RM representative of the average productivity of the preceding
periods and, for the subsequent period, increasing/decreasing loom speed by a preset
value ΔV, depending on the fact whether RMn is greater or smaller than the reference
RM.
