Abstract

Winding device (23) designed to form a rectangular tubular transverse coil (1) by alternately repeating a bending of a rectangular conductor (2) in a predetermined direction in a lateral manner and a feeding of the rectangular conductor (2), comprising the following: a bending device (31) arranged to be able to come into contact with an outer surface (2a) of the rectangular conductor (2), wherein the bending device (31) is designed to be driven in the predetermined direction and thereby bend the rectangular conductor (2) laterally; five tilt-prevention guides (50, 501, 502, 503, 504, 505) arranged at equal intervals around the same circumference to prevent the transverse coil (1) from losing its shape, wherein the five tilt-prevention guides (50, 501, 502, 503, 504, 505) are designed such that when the rectangular conductor (2) is bent laterally, the transverse coil (1) is guided between two adjacent guides of the five tilt-prevention guides (50, 501, 502, 503, 504, 505) in the predetermined direction; and a guide holding component (51) designed to hold the five tilt prevention guides (50, 501, 502, 503, 504, 505) and to be driven in a rotating manner in synchronization with the bending of the rectangular conductor (2) in the lateral manner and the feeding of the rectangular conductor (2).
