Abstract

PURPOSE: To detect the abonomal shape of a running wire in the widthwise direction thereby to produce a warning by providing a pair of switches, which are arranged in the vicinity of the running wire at a spacing slightly larger than the width so that they are operated in response to the approach of the wire and by scanning the switches.
CONSTITUTION: Along a running wire 1, there are arranged a pair of switches 2 at a spacing L larger than the width l through a holder 3. The switches thus arranged are traversed widthwise of the wire 1 by a traverser 4 so that they may be scanned. When the wire 1 runs so that the paired switches 2 are scanned in the direction of arrow, one of the switches 2 is left inoperative while the other is operated. If a protrusion A exists at the corner of the wire 1, the paired switches 2 are simultaneously operated to generate a warning which informs that an abnormal shape takes place.
