Lacing method of stator

An object is to provide a lacing method for stators, which is capable of automatically effecting lacing with respect to the coil ends of stators different in diameter. Before lacing is effected with respect to the coil end of a stator, an eccentricity (A) between the movement axis (Z2) of a thread supply nozzle (5) and the rotation axes Z1a, (Z1) of the stators is calculated on the basis of the inner diameter of the stator and the nozzle length of the thread supply nozzle (5). When lacing is to be effected with respect to the coil end (2a) of a stator (1a) whose diameter differs from a reference diameter, the stator (1a) is moved in such a manner as to deviate the rotation axis (Z1a) of the stator (1a) by an amount corresponding to the eccentricity (A) from the movement axis (Z2) of the thread supply nozzle (5), so that lacing can be effected with respect to the coil end (2a) of the stator (1a) while the thread supply nozzle (5) is still used without changing the movement locus of a hook (4).
