ABSTRACT OF THE DISCLOSURE The present invention provides a method of fastening parts securely in place by a band comprising the step of winding using a band winding device a band around each of tight-binding portions of a plurality of parts fitted over an article to which said parts are to be fastened and applying a laser beam emitted from a laser beam irradiation head to the overlapped portion of both ends of the band for welding thereof, including conveying the article successively to a plurality of working stations, each equipped with a band winding device, and performing at each of the working stations the band-winding for each of the predetermined tight-binding portions of the parts; and dividing a plurality of the band winding devices disposed at said working stations into at least two groups, one group comprising those in front along the conveying direction in which the article is conveyed and the other group comprising those in the rear, and moving a laser beam irradiation head, which is one of the irradiation heads provided one per group of the band winding devices, successively to a position at which it is aligned with each of the band winding devices belonging to the corresponding group so as to be prepared for welding the band, wherein said movement of one of the laser beam irradiation heads is alternate with that of the other one and, while said one laser beam irradiation head is being moved, a laser beam emitted from a common laser generator is led into the other laser beam irradiation head to carry out the welding. The present invention also provides an apparatus for using the method.
