<p>The device for the formation of skeined sections on thin metallic wires is of the type in which the wire to be skeined extends from an inlet point (9) to an anchor point (15) and is placed under traction by a wire tightening device (2). A branch of said wire emerging from said anchor point is sent to a wire tightening device (8) controlled by an electronic control system which controls the skeining operation. The wire tightener being present the following parts: a pulley (28) connected to an electromagnetic brake (29) with electromagnetic hysteresis; a second pulley (27) located above the first pulley (28) sensitive to the load bearing and sending a signal signifying the load to the control system which regulates the braking action of the brake. The wire descends on a first side of the above mentioned second pulley (27) and then winds on the first pulley (28) and returns to the second side of the second pulley (27) on which it winds for 180 and then again descends on the first side towards a wire winding machine (5) located downstream.</p> |
