ABSTRACT:
A wire shear has a pair of vertically superposed cutter drums defining a nip and having at least one cutter blade. These drums have parallel axes defining a vertical plane. A swingable elongated guide tube has a downstream end closely juxtaposed with and directed into the nip. This tube is mounted at its upstream end for swinging about vertical and horizontal axes at the upstream end. A wire is fed into the upstream end at high speed. A cooling sleeve surrounding the guide tube has lateral openings through which a coolant is introduced into the interior of the sleeve to cool the tube and the wire in it. An upstream guide is engageable upstream of the plane with the downstream end and with the wire issuing therefrom and extends into the drum nip substantially to the plane. A downstream guide downstream of the plane is aligned with the upstream guide and has a floor plate extending upstream substantially to the plane and a guide wall extending upstream past the plane and past the downstream end. The upstream guide can be raised to lift the downstream end of the guide tube and feed the wire issuing therefrom into the nip of the cutter drums.
