To facilitate setting of a stationary angle in which load in ashedding driving motor is considered.

A torque detection circuit 19 constituting an shedding controller Cl calculates torque from electric current value fed from a driving circuit 18 to an shedding driving motor 12. A detection torque Fx detected by the torque detection circuit 19 is compared with a standard torque F0 stored in a standard torque storage circuit 17 in a comparison circuit 20. The stationary angle selection circuit 21 selects a stationary angle based on a comparative result in the comparative circuit 20. An shedding pattern-producing data 22 produces actual shedding pattern based on shedding pattern data (shedding pattern in which stationary angle is 0) which become a standard obtained from a loom control computer C2 and a stationary angle selected in the stationary angle selection circuit 21.
