Abstract (en)
[origin: EP0768124A2] The rolling apparatus 1 comprises a first roller-couple 101a,101b and a second roller-couple 102a,102b which are arranged adjacently in a feeding direction of work material A1 and roll the work material A1 in different directions each other successively. Each of the first and second roller-couples comprises two rollers each of which has a groove for determining the cross sectional shape of the wire on the circumferential surface thereof. The width of the grooves are less than 7 mm for the first roller-couple 101a,101b and are less than 6 mm for the second roller-couple 102a,102b. The center distance between the first and second roller-couples 101a,101b and 102a,102b is less than 50 mm. <IMAGE>
