Abstract

A wire (10) is bent into a zigzag shape by being clamped at two spaced-apart points while a hook (20) engages a point of the wire midway between the two points and pulls the wire against an abutment (31). One of the points is thereafter dis­ placed linearly towards the other point while the hook and the abutment (31) are being pivoted in a circular arc with the other point as centre of pivotment.
