在拉丝机（1）与2中的恒定变化绘图滑架（5，35）操作时，所述夹爪的控制（6,7），其布置在由机器主体（2）的曲线（11）。 一个绘图托架abkragender夹紧杆（10）的移动曲线上并按压夹爪（6,7）上的导线（8）。 因此，该电线甚至不夹紧，当在其返回到曲线绘图滑架（11）通过，被形成在铰接在机体舌的曲线（16）或所述夹紧杆的拉伸滑架的返回路径（10）上 。在其上安装辊子（22）被推开。 舌是由抵靠止动件（18）的弹簧（14）按压，并且当在滑动高程的前死点的滚子（22）具有通过所述舌片（16）通过弹回。 在杆（10）和夹紧杆（38）之间的运动链为“软”按压夹持所述线的夹爪的扭杆（19）被提供。 在每个夹持滑架的牵引路径的端部设置的解锁装置（21）。

At a drawing machine (1) with two working in constant alternation drawing carriage (5, 35) controlling the clamping jaws (6, 7) of a machine body (2) arranged curve (11) is made. One of the drawing carriage abkragender clamping lever (10) moves over the curve and presses the clamping jaws (6, 7) on the wire (8). So that the wire is not even clamped, when the drawing carriage passes on its way back to the curve (11), the curve is formed on an articulated on the machine body tongue (16) or on the return path of the drawing carriage of the tensioning lever (10) . the mounted thereon roller (22) is pushed aside. The tongue is pressed by a spring (14) against a stop (18) and snaps back when the roller (22) has passed through the tongue (16) in the front dead center of the slide elevation. In the kinematic chain between the lever (10) and the clamping levers (38) is a torsion bar (19) for a "soft" pressing of the clamping jaws of the wire is provided. At the end of the pulling path of each clamping carriage an unlocking device (21) is provided.
