Method for manufacturing a stator of a dynamo-electric machine, said method comprising the following steps: - forming coil members by bending an electric conductor externally coated with an outer insulation; wherein the bending is made at predetermined lengths from a reference position, and wherein each one of the coil members, when formed, comprises at least one head portion and leg portions (21") extending from said at least one head portion; - feeding the electric conductor to accomplish the bending; - cutting the electric conductor to detach a formed coil member from said electric conductor; - inserting the leg portions (21") of the coil members into slots of the stator, so that parts of said leg portions (21") extend from one end of the stator and the head portions extend from an opposite end of the stator; the method being characterized in that it comprises, furthermore, the step of: - arranging at least one laser beam (13'a, 13'b) to remove the insulation from predetermined areas (20a, 20b) of the electric conductor; - radiating the surface of the electric conductor with said at least one laser beam (13'a, 13'b) situated at a predetermined position (1P, 2P) with respect to the reference position along the length of the electric conductor being fed, and at a predetermined stage of the bending of a coil member; - radiating said at least one laser beam (13'a, 13'b) on multiple zones of the predetermined areas (20a, 20b) by moving said at least one laser beam (20a, 20b) with a predetermined movement; and - synchronizing the movement of said at least one laser beam (13'a, 13'b) with the movement of the feeding of the electric conductor; and in that the synchronization occurs by summing the speed of movement of at least one laser beam (13'a, 13'b) to the speed of the movement of the feeding of the electric conductor. - forming coil members by bending an electric conductor externally coated with an outer insulation; wherein the bending is made at predetermined lengths from a reference position, and wherein each one of the coil members, when formed, comprises at least one head portion and leg portions (21") extending from said at least one head portion; - feeding the electric conductor to accomplish the bending; - cutting the electric conductor to detach a formed coil member from said electric conductor; - inserting the leg portions (21") of the coil members into slots of the stator, so that parts of said leg portions (21") extend from one end of the stator and the head portions extend from an opposite end of the stator; - arranging at least one laser beam (13'a, 13'b) to remove the insulation from predetermined areas (20a, 20b) of the electric conductor; - radiating the surface of the electric conductor with said at least one laser beam (13'a, 13'b) situated at a predetermined position (1P, 2P) with respect to the reference position along the length of the electric conductor being fed, and at a predetermined stage of the bending of a coil member; - radiating said at least one laser beam (13'a, 13'b) on multiple zones of the predetermined areas (20a, 20b) by moving said at least one laser beam (20a, 20b) with a predetermined movement; and - synchronizing the movement of said at least one laser beam (13'a, 13'b) with the movement of the feeding of the electric conductor; and
