Claims

[Scope of utility model registration request]

A commercial power source, a variable frequency inverter, an induction type driving motor for driving a loom, a contact point of a starting relay interposed between this driving motor and the commercial power source, and a connection point between the driving motor and the inverter. A contact point of a relay for normal operation interposed therebetween, a comparison means for comparing the output frequency of the inverter and the rotation speed of the loom, and a rotation speed at which the rotation speed at the initial startup of the loom is the rotation speed at which the loom is operated at the output frequency of the inverter. A loom operating device characterized by comprising: switching means for setting the starting relay in the on state to the off state and switching the normal operation relay to the on state when the starting relay reaches the on state. .
