Abstract: In order to increase the operational safety of an unreeling apparatus and an unreeling method at high working speed, an unreeling apparatus for unreeling a ring of wire along a pull-off direction, having at least two reel crowns, which can each be brought into a pull-off position and into a preparation position and/or loading position by way of a displacement device, includes a safety apparatus having an overload safety device and having a safety guide track, which has a directional component that faces in the pull-off direction and acts independently of the other reel crown, at least for the reel crown situated in the pull-off position, wherein the overload safety device holds the reel crown situated in the pull-off position in the pull-off position and, in the event of an overload, releases the reel crown situated in the pull-off position into the safety guide track.

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 at 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.
