ABSTRACT:
An apparatus of the present invention for blowing a cable has a meandering detection section provided adjacent to a feeding rollers. The meandering detection section includes a straight passage for the cable passing therethrough, a recessed portion being arranged on a wall of the passage, and a detector detecting the cable meanderingly entering into the recessed portion. When there is no entering of the cable into the recessed portion, the cable is in the normal insertion condition. On the other hand, when the cable meanders at a short pitch entering deep into the recessed portion, the detector detects the abnormality of the insertion, and the feed speed is controlled to cancel the meandering of the cable.
