Abstract: A caterpillar-traction drawing machine and a method for drawing of elongated workpieces can be provided with at least one drawing tool fastened pivotally on a tool holder and/or with at least two identical drawing recesses, which can be brought selectively into a drawing position, so that the influence of any fatigue phenomena that may exist is minimized. For the same reason, a caterpillar-traction drawing machine is advantageous in which the two chains of the caterpillar-traction unit are block chains and are respectively braced via an idler roller chain including idler rollers on respectively one pressing beam.
