ABSTRACT:
There is disclosed a device for extracting the end portion of wire rod from a laying guide of an Edenborn coiler arranged downstream of a wire rod rolling mill. The device includes an extractor cylinder idly supported by the laying cone of the coiler so as to be substantially stationary during rotation of the coiler or to slightly rotate in a direction opposite to that of the coiler. The cylinder has a diameter slightly smaller than that of the formed coils and a length such as to comprise at least one turn of the deposited coils. When the end portion of the wire rod has leaved the rolling mill and is no more dragged by pinch rollers or the like at the output of the rolling mill, the speed thereof decreases due to friction against the walls of the output guide located between the rolling mill and the coiler. The diameter of the coils therefore also decreases and the wire rod winds around the extractor cylinder which has a relative speed with respect to the coiler, thus causing the end portion of the wire rod to be extracted from the continuously rotating laying guide of the coiler.
