A bending machine for elongated articles in which a rotatable bending platen supports bending tools, adjustable setting means control the rotation of the bending platen through predetermined principal bending angles, with an electrically operated control system continuining any bending operation through a predetermined supplementary angle after bending through the principal angle has been accomplished. An adjustable delay device is operably associated with each principal bending angle and is arranged to coact with a motor for driving the bending platen so that the motor remains activated for a further period of time after a given principal bending has been reached for effecting bending through the supplementary bending angle.
