PROBLEM TO BE SOLVED: To solve the occurrence of weaving bars that are caused by insufficient beating power on the start of weaving. SOLUTION: When a weaving machine is driven, the machine is allowed to start with the commercial power source at a larger rotation number than that of the steady rotation to effect the beating, then the weaving machine is reduced in its rotation with the output of the inverter toward the steady rotation. Thus, the beating power is increased at the start whereby the occurrence of weaving bars is inhibited. |
