Abstract
A point tool assembly includes a vertical moving table disposed on a forming table and movable in a direction parallel to the forming table surface and perpendicular to the feed direction of a wire, and a longitudinal moving table disposed on the forming table and movable in a direction parallel to the forming table surface and the feed direction of the wire independently of the vertical moving table. A link arm moves a parallel slide table and first and second inclined slide tables the same distance upon longitudinal movement of the longitudinal moving table. A forming table includes first and second independent tool drive units for supporting first and second point tools in positions where the first and second point tools oppose the wire and moving the tools in a direction substantially parallel to the forming table surface and substantially perpendicular to the feed direction of the wire and in a direction parallel to the forming table surface and the feed direction of the wire. The first and second tool drive units are controlled independently of each other so that the end portions of the first and second point tools draw predetermined loci.
