ABSTRACT:
A pipe bending machine includes a horizontal pipe support platform defining a horizontal pipe feed channel. A first pipe engaging member is positioned on a first side of the pipe feed channel. A second pipe engaging member and a third pipe engaging member are arranged in spaced relation on a second side of the pipe feed channel. Either the first pipe engaging member or the second pipe engaging member and third pipe engaging member are movable into the pipe feed channel, thereby exerting a bending force upon a pipe positioned in the pipe feed channel.
