Abstract

PURPOSE:To enable adjustment of a lap amount, by a method wherein, in a taping device by which taping is conducted on a slender conductor for use in a rotary electric machine, a driving motor rotates a taping ring and moves a moving body, and a variable speed motor delays movement. CONSTITUTION:A conductor (a) being a work is inserted through a taping ring 9, and an insulating tape (b) in a feed reel 10 is pasted to the starting part. Thereafter, with a driving motor 11 of a moving body 6 driven, the worm 16 of a first worm device 12 is rotated through a chain 14, and a tape (b) is wound through rotation of a large gear 8 of a taping ring 9 via a small gear. Simultaneously, the moving body 6 is moved via a transmission chain 25 through rotation of a worm wheel 17 to perform 1/2 lap taping. In which case, with a reversible speed motor 29 driven, the transmission chain 25 is driven through a second worm device 26 to relatively delay the moving speed of the moving body 6, and for example, 1/3 lap taping takes place. This enables free adjustment of a lap amount.
