A device for cropping and deflecting a wire-rod strand moving at high speed, comprising two rotating cutter heads, each having a cutter and arranged one on top of the other, one cutter being a leading cutter and the other cutter being a trailing cutter, and a switch tube arranged between the two cutter heads, for forcibly guiding wire-rod strand between the two cutter heads to separate a head piece of the wire-rod strand not conforming to the quality requirements from the strand. There is an outlet having guide channels separated from each other for receiving the head piece of the wire-rod strand and the wire-rod strand. There is a fin arranged on each of the cutter heads, a leading fin directly in front of the leading cutter in the direction of rotation of the corresponding cutter head, and a trailing fin directly behind the trailing cutter in the direction of rotation of the corresponding cutter head. The axes of rotation of the cutter heads are inclined in a horizontal plane by an angle of inclination toward the rolling direction such that before, during and after separation of the head piece, an end of the head piece is deflected by the leading fin to one side and an end of the strand is deflected before, during and after separation by the trailing fin to the opposite side by forced guidance. The deflection takes place sequentially over time.

Device for cropping and deflecting a wire-rod strand

A device is described for straightening a curved steel strand cast continuously by means of a casting wheel machine or a curved mold continuously casting machine. The strand is passed between straightening points with rolls, such as straightening, bending, guide, counter rolls and/or corresponding roll pairs, in accordance with a certain physical law, whereby at least two roll pairs applying bending moments to the strand are provided. The first roll pair is at the same time the roll pair located in the direction of travel of the strand directly downstream of the point of emergence of the strand from the casting machine or is formed by the casting wheel (of the curved mold) itself and a corresponding straightening roll. The second roll pair determines transition of the strand from a finite radius or curvature to a straight line (infinite radius of curvature) at the end of the bending zone. Between these two roll pairs other rolls can be located exclusively along the outside of the strand.
