A pipe bending machine has a slider connected to a piston for actuating a drawing roller movable during an working pass between a rest position and a bending position. A flow control means is provided for adjusting the pressure in both piston chambers allowing the drawing roller to precisely reach the bending position at the end of a bending stroke, and the rest position at the end of the return stroke. Accurate control of the slider motion during one working pass is obtained without adjusting the roller speed. Elongated pipes can be round shaped along curvatures with differing radiuses without leaving marks on the pipe surface while avoiding mechanical stoppers or costly roller speed adjusters.
