PROBLEM TO BE SOLVED: To make manual marking disk replacement unnecessary by providing a chained roller part wherein multiple marking disks are arranged in parallel where different marking grooves are formed on the circumferential surface. SOLUTION: The forefront marking disk 22a of a chained roller part 20a arranged in parallel, for instance, is selected by selecting a lateral changeover switch 157 and then switching a disk selection switch 157. And then when a roll movement switch 156 is turned on, the chained roller part 20a moves together with the second moving table 66a by a changeover driving mechanism 60a, the forefront marking disk 22a is placed on the electric wire feeding line 12 side. And then when an automatic operation mode is selected by operating an operation mode selector switch 152, the forefront marking disk 22a gets into a waiting state where it is disposed on electric wire feeding line 12 side. After that, when a electric wire 11 is fed, the operation state is resumed, a mark is added to the electric wire 11 fed by a marking groove in the circumferential surface of the disk 22a. |
