- 1 - PIPE-BENDING APPARATUS ABSTRACT A pipe-bending apparatus comprises an elongate structure having a longitudinal work surface at, or adjacent to, opposite ends of which clamping means and a former are respectively mounted. The former is held fast on the work surface, and the clamping means is power-driven towards and away from it by a double-acting hydraulic ram. A series of formers are provided, each having, in plan, a semi-circular anvil mountable to face the clamping means. The anvils are each of concave vertical cross-section and-of different radius from one another, with peripheral walls to locate a pipe in position in the anvil during a bending operation. The ram is supplied from a tank containing a hydraulic fluid tank which - together with the necessary hydraulic pump and electric motor - is mounted beneath the work surface.
