Title:
PRODUCTION DEVICE AND PRODUCTION METHOD FOR EXTRA-LONG TOOL
Document Type and Number:
WIPO Patent Application WO/2006/019163
Kind Code:
A1
Abstract:
An extra-long tool producing device comprising a plating solution tank (401), a plating bath (402), a staring cathode (403), a terminating cathode (404), a starting anode (405), an intermediate anode (406), a terminating anode (407), and pulleys (115). An auxiliary movable electrode (501) is provided between pulleys (115, 115) in the device. The auxiliary movable electrode (501) assists in feeding a linear raw material (102) while supplying a cathode current to the linear raw material (102). The presence of the auxiliary movable electrode (501) shortens the distance between an anode and a cathode to ensure a current required for a plating process. Since the linear raw material (102) rotates, the abrasion of the auxiliary movable electrode (501) or a spark from it otherwise caused by abrasive grains electro-deposited on the linear raw material (102) can be prevented in the auxiliary movable electrode (501).
