Abstract
A main drive shaft of a power loom reaches the rated operating rpm of the loom by the time of the first beat-up of the reed, thus avoiding start-up faults in the fabric. A flywheel mass is accelerated to a start-up rpm that is higher than the rated operating rpm before it is coupled with the main drive shaft. The start-up rpm is determined automatically and iteratively, with ever-increasing accuracy in successive starts of the loom. When the main drive shaft is coupled to the flywheel mass, the flywheel mass rpm decreases simultaneously as the main drive shaft rpm increases from standstill to the operating rpm. The actual main drive shaft rpm is measured at least at the time of the first beat-up and any deviation from the rated operating rpm is evaluated by the loom control. After each start-up, a new data set is generated based on the measured values and is used to calculate an updated or modified flywheel start-up rpm in the next start-up operation so that the main drive shaft more accurately reaches at least the rated operating rpm by the time of the first beat-up of the reed.
