Abstract

A method of forming wire or rod into circles comprises feeding the wire or rod around a circular path until its leading end encounters a fixed end stop, then urging the end of the wire or rod against the end stop so that the metal, circle tends to expand into engagement with a plurality of peripheral stops and cutting the wire or rod. Wire F is fed by rolls 1, 3, 5 to curve-forming means comprising rolls 7, 8 together with a wire-cutter 9 comprising two plates with aligned holes. The curved wire then passes inside a ring of six grooved vertical rolls 10 followed by four ungrooved vertical rolls 11, being also guided by horizontal rolls 12 arranged on a helical path adjacent the rolls 11. The end of the curved wire then abuts a stop 13 and the wire is consequently urged outwardly against the rolls 10, 11. The curved wire is cut by the cutter 9 and returns to its original radius of curvature and non-helical form with its ends overlapping or slightly parted.
