Abstract

A machine for converting straightened wire into an elongated undulate comb-like product wherein hairpin-shaped prongs alternate with webs which extend in the longitudinal direction of the product has two carriers which are rotatable about parallel axes and have neighboring end faces defining a forming channel. Each carrier supports a group of equidistant tools which are reciprocable in parallelism with and are equidistant from the axis of the respective carrier. The carriers are alternately indexed in opposite directions, and the wire is fed into the channel by a pivotable portion of a wire feeding unit so that it is alternately engaged by successive tools of the one and the other carrier. The tools are shifted into the channel before they engage the wire, they remain in engagement with the wire while the respective carriers dwell between successive indexing movements, and they are thereupon retracted from the channel not later than when the respective carriers are indexed again whereby the tools are automatically separated from the wire. Levers are provided to urge the wire against the tools in the channel.
