Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To effectively clean an electrifying wire and to prevent leak by holding the electrifying wire between each pair of cleaning pads when cleaning, and uncovering the electrifying wire when not cleaning. SOLUTION: After cleaning, first and second cleaning members 1 and 2 and a hold case 3 are moved near a home position which is near the end of the electrifying wire, a separation member 4 is forced between the pad holders 2-1 and moves the pads P-2 apart from each other to the right and left, thereby uncovering the electrifying wire.
