Abstract

A wire or strip bending machine has bending tools (1,2), each of which can act as an active tool or mandrel, mounted on an arm (3) which is slidable in a slot (11) in a rotatable disc (10). The disc is rotatable via gearing (13,14) to rotate one of the tools about the other, to bend material between the tools.
