Abstract (en)

[origin: US4774824A] In an apparatus for feeding self-hardening hot rolled wires from supply reels to a consumer and for straightening the wires, in each feed path there is a rotor-type straightening device (3) with a straightening rotor (3b) deflecting the wire (1) radially between two fixed wire guides (3a) and rotating at high speed; the wire forms loops (12, 16), in front of and behind the rotor-type straightening device (3), the front loop (12) having assigned to it a sensing means (5, 8, 10) which switches off the rotor-type straightening device (3) when the length of this loop falls below a minimum value, while assigned to the rear loop (16) are two switches (18, 19) which, when a maximum or a minimum permitted length of this loop is reached, control the rotor-type straightening device (3) so as to correct the loop length.
