Abstract

Method and device for detecting defects of the wire in thread wipers, in which the cross section of the wire is continuously felt by appropriate sensitive organs and transformed into a corresponding electrical signal, a procedure characterized in that together with the cross section and the length of the wire defect, its frequency or periodicity is also verified and it is made to contribute as a criterion so that when regular or irregular sequences of thick places appear, a signal is triggered and/or a indicator means is triggered as a warning of this defective thread.
