Abstract: A wire stripping apparatus with a mechanism which cuts lead wire to a specified length, and peels off the covering of both ends of the wire before wiring it; through the attachment of a supply finger which conveys the wire to a predetermined position on the printed circuit board or similar for fixing, and positions it there, the device can supply the wire thus obtained to the next process. An automatic wiring device which can automatically perform wire coiling and soldering in a process continuous with the construction of said wiring by combining the work of this wire stripper with an automatic coiling and soldering device.
